Odom v. Microsoft: Using Your Own Patents as Prior Art

[UPDATED August 18, 2011 to Reflect the Fact that the Christopher Brown mentioned here is not Christopher Brown, CTO of OPSCODE]

Odom v. Microsoft (Fed. Cir. 2011)

By Dennis Crouch

I previously wrote about the Federal Circuit affirmation of the lower court’s summary judgment ruling that Odom’s claims are obvious when judged against a single prior art patent.  

The prior art patent in this case is Patent No. 6,057,836 and is owned by the defendant, Microsoft. The inventors on Microsoft’s ‘836 patent include Jude Kavalam (now CTO at Spoken Communications), Christopher Brown (now CTO at Opscode) and Jeff Bogdon (named inventor on 25+ patents).  The ‘836 patent provides a mechanism for users to re-size toolbar groups and has a number of similarities to the invention that Odom claimed in his patent and the appellate panel identified the advances offered by Odom as “insignificant.” Odom has now petitioned the Federal Circuit for a rehearing.

An interesting aspect of this set-up is the way that Microsoft used its patent as a priority document to help establish its freedom to operate rather than as intellectual property per se.  Microsoft could have achieved the same results by simply publishing its prior invention. Likewise, in the US, Microsoft could have relied on its prior-inventor rights under 35 U.S.C. 102(g).  However, the patent-as-prior-art approach has a number of advantages over these alternatives. Of course, alternative approaches are not mutually exclusive and instead can each be part of a layered strategy of protection.

Creating Prior Art – Patent versus Publish: Under 35 U.S.C. 102(a) & (b), any prior publication has the same weight as a prior patent or published patent application. An issued patent additionally offers intellectual property rights. However, even apart from those IP rights, there are several reasons why a company may choose to file for patent rights when attempting to create prior art to forestall infringement litigation.  First, because a patent application will be considered prior art as of the date of filing (once published or patented) under 35 U.S.C. 102(e), the company can establish a prior art priority date without actually publicly disclosing the invention for at least 18 months. This delay in publication will often be seen as valuable.  The patent approach also comes with a guarantee that the document will qualify as prior art as of a specific, known date — as opposed to a non-patent publication that will be judged and timed according to the sufficiency of distribution or indexing. In addition, the patent rules force a more complete disclosure and therefore may result in better documentation of the invention and a broader scope of disclosure than what would have been otherwise published.  Finally, a patent may well provide a sense of authority and an equitable claim-to-right that would not accompany a mere publication.

Creating Prior Art – Patent versus Prior Inventor Rights: In the US, a prior inventor can also invalidate a patent by proving prior invention under 35 U.S.C. 102(g).  However, that approach is fraught with potential doctrinal difficulties and a patent disclosure offers a much cleaner mechanism.  These difficulties may well have arisen in this case. For instance, Odom presented evidence of Microsoft’s recognition that the Kavalam project was unable to achieve the the results claimed by Odom. And, several years later (well after Odom’s priority date), Microsoft finally filed for patent protection on what is arguably Odom’s invention — arguably recognizing that Odom’s invention is distinct when compared with Kavalam.  These facts suggest that perhaps Microsoft would not fare well in a 35 U.S.C. 102(g) argument.  Adding to this difficulty is the extensive paper trail requirement for proving 35 U.S.C. 102(g). 

Four Corners of the Prior Art?: The district and appellate court decisions considered the Kavalam patent on its face and did not bite on any of Odom’s arguments regarding Microsoft’s actual activities and admissions that could have limited the interpretation of the disclosure.  This approach simplifies the analysis, but it is probably wrong once the case steps into the question of obviousness — especially when the alleged prior art was created by one of the parties to the lawsuit.  In KSR v. Teleflex, the Supreme Court ordered that courts apply a flexible, common sense approach obviousness. Here, that guidance seems to mean that a court should consider extrinsic facts that tend to expand or limit the interpretation of the prior art reference. 

Notes:

  • Odom’s patent issued from a continuation application. Odom cited the Kavalam patent in the parent case, but did not re-submit the patent in the child case (examined by the same examiner) and the Kavalam patent is not listed on the face of the asserted patent.  The Federal Circuit opinion implicitly suggests that this prior art was not considered by the examiner. Those who disagree may want to support the rehearing request.

    Gone are the days of “local novelty”, when patent rights were handed out to people who brought back to the homeland useful inventions spotted in faraway lands and still unknown in the homeland.

    These days, inventions are made by inventor employees each sitting at a PC in a different part of the world, and working together as a team. Would you not agree then Ned, anything other than absolute novelty is, these days, ridiculous.

  2. 179

    Max, you may be right at least prospectively. It was one of the main objectives of the drafters to have one prior art for any US patent regardless of origin. This helps explain why the choice of universal public use as opposed to limiting even that to the United States.

  3. 178

    ….and if the Bill passes into law, the Hilmer Doctrine then passes into history, right Ned?

  4. 177

    I assume you do know that you can file provisionals in any language and get a US filing date that is good even for prior art purposes.

    Filing PCT is not filing in US to the extent that a patent is pending in the USPTO that can issue but for US patent office delays. That requirement was the essence of why the US Supreme Court required US patent applications to have a prior art (deemed published) effect as of their US filing dates.

    I hope you can see, the essential requirement for prior art effect is pendency of an application in the USPTO. Priority is an entirely different matter.

    Now, as to PCTs. The US specifically reserved the right to treat the prior art effect of PCT applications according to its own law. The US is not violating either the Paris convention or the PCT Treaty in according priority only effect to PCT or foreign patent applications.

  5. 176

    Yeah, sure. Asking someone to write in a foreign language when the other can use its mothertongue —> treating both of them alike.

    American exceptionalism much?

  6. 172

    But, if you subsequently file PCT and then file US or enter the national stage, whether that provisional’s filing date is the effective prior art date is open to question.

    No. It is not open to question.

  7. 171

    Thanks Ned. I agree with you, that one’s 103(e) date “should not depend” on these things.

  8. 170

    That’s not the point at all. It has to do with whether the effective prior art date is the date of the earlier US application to which a PCT claims priority. I know you folks in Europe have said that filing a provisional in the US is your preferred Hilmer dodge on prior art (it can be filed in German, for example). But, if you subsequently file PCT and then file US or enter the national stage, whether that provisional’s filing date is the effective prior art date is open to question. The answer should not depend upon whether the PCT was published in English or not, or whether the US stage is entered directly or indirectly through a continuation.

  9. 169

    Thank you Ned. Your summary, together with Cy’s last reply (“Yawn”) to my similar summary, finger the significance of Hilmer.

    As to the PCT point, I will look again at the Apple thread, but I had thought the national v. continuation point had been appreciated for very many years already.

  10. 168

    Max, if both parties get out of the PTO unscathed, it is my experience that neither will sue each other for infringement or for an interference. The public as well has to pay/license both because they too do not know who invented first. The PTO has no way of revoking one against the other without an interference.

    So, Hilmer does cause a problem, but it is not the same problem you expected. It allows two apparently valid patents on an invention that can only be resolved by an interference that neither party will provoke.

    Also, check the Apple thread for something on the prior art effect of patents claiming from or through a PCT to an earlier-filed US application or provisional.

  11. 166

    Well that’s a comfort for A, I must say. An invitation to bankroll top drawer outside counsel 20 years long (Cooper/Goldfarb) to play Russian Roulette with your head? No wonder interferences are so rare.

    Meanwhile, what recourse does every other person in the world have, faced with two established players both in possession of enforceable patents on the same invention? For some reason, the words “patent thicket” spring to mind.

    But now I think we really are through with this issue, don’t you?

  12. 165

    …what we have now is the second to invent exactly the same invention holding a patent on that invention which is just as valid and enforceable as the patent issued to the quicker-thinking and more nimble rival who was first to invent and first to file (but just not within the USA).

    Except that it’s not “just as valid and enforceable.” Your quick-thinking and nimble foreigner still has recourse to an interference proceeding under 35 USC 291.

  13. 164

    Cy, you write about B, who conceived later, reduced to practice later and filed later, but was earlier into the USPTO, that:

    “I don’t believe there are any rejections available to the examiner in B’s case”.

    In my scenario, A and B were both German, and B jumped the queue in the USPTO. But what I really had in mind was a situation in which A and B are competitive and successful world-wide rivals, A invents in a Paris Member State other than the USA, while B does his inventing within the USA. Each is diligent, and each is equally quick from conception to constructive reduction to practice.

    Corporations these days need a pile of issued patents to have “something to trade”. So, best if Johnny Foreigner gets no US patent at all but, if America can’t find any reason not duly to issue him with one, then the next best thing for America is duly to issue his slower US competitor with one to match.

    You also write: “The good news is that the present situation, in which most potential interferences aren’t even noticed, gets us to about the same place.”

    in which, I suppose, the key word is “about” in that an interference leaves a winner and a loser, whereas what we have now is the second to invent exactly the same invention holding a patent on that invention which is just as valid and enforceable as the patent issued to the quicker-thinking and more nimble rival who was first to invent and first to file (but just not within the USA).

    My admiration of the thinking behind the Hilmer Doctrine grows by the minute.

  14. 163

    Give me a sample rejection in B’s application. Keep in mind, Hilmer II.

    Ned, with all due respect, I’m happy to learn from a conversation, but please don’t quiz me like I’m your student.

    As I said earlier, I’m no expert on interference practice. But, I don’t believe there are any rejections available to the examiner in B’s case, in this situation. He or she can, I believe, require the addition of an interfering claim under 37 CFR 41.202(c), but I expect that this is entirely discretionary. I understand that you find that to be a huge problem. It doesn’t concern me very much, for reasons I’ve given elsewhere in this thread.

    Max was right. We’ve thrashed this one to death.

  15. 162

    I much enjoyed your assessment that “In an ideal world” every one of these priority contest situations would go to interference proceedings.

    You’ve misunderstood me – I can’t tell whether it’s intentional or not.

    I said that in the ideal world, each potential interference issue would get raised. In that same ideal world, in the vast majority of incidents the junior party would assess the situation, realize that a full-blown priority contest is fruitless, and concede the claims. 37 CFR 41.202 already accounts for that.

    The good news is that the present situation, in which most potential interferences aren’t even noticed, gets us to about the same place.

  16. 160

    Very helpful Cy. Thanks again. Do I see it right? In practice, the PTO will be issuing both A and B with a patent on the same invention? Would you call that a win-win?

    Incidentally, I much enjoyed your assessment that “In an ideal world” every one of these priority contest situations would go to interference proceedings. Bravo.

  17. 159

    Huh?

    From link to chicagoiplitigation.com

    Schultz v. iGPS Co. LLC, No. 10 C 71, Slip. Op. (N.D. Ill. Jan. 3, 2011) (Hibbler, Sen. J.)
    Judge Hibbler granted in part defendant’s Fed. R. Civ. P. 15 motion to amend its affirmative defenses. The doctrine of assignor estoppel did not ban defendant’s invalidity and inequitable conduct defenses. An assignor is estopped from challenging the validity and enforceability of its assigned patent, but that estoppel is personal to the assignee. Because plaintiff was not the assignee, he had no right to assert estoppel. Furthermore, to determine whether defendants were in privity with the assignor would require facts beyond the complaint and was, therefore, not resolvable in a motion to dismiss.”

    Personal? Sounds like the DC treated legal estoppel as equitable estoppel.

  18. 158

    Cy: “B’s application gets flagged.”

    There’s the problem in a nutshell.

    Give me a sample rejection in B’s application. Keep in mind, Hilmer II.

  19. 157

    Cy, yes I know the PTO usually lets the parties fight it out outside the PTO as IF it really did not matter to the public that two rival entities have obtained a patent on the same subject matter.

    But it does matter.

    There is a well known recent case where two major computer companies independently patented the same invention that became widely used as the preferred compression technique. Both companies licensed their respective patents. Many companies paid royalties to one company even though they already held a license under the other company’s patent.

    The problem existed during the entire life of both patents, yet neither patentee chose to resolve the situation through an interference. They were content to hold the royalties below the threshold level of pain that would justify a DJ action. But, if the only defense is that the patented invention was invented first by a third party, how is an accused infringer supposed to know the answer to that question in advance so that they could even properly allege it in a pleading?

    I would argue that such cavalier disregard of the public interest has to be condemned.

  20. 156

    What indeed should the Examiner do, who is examining A’s PTO filing, finds himself looking at B’s earlier USPTO filing on the same invention, thinks about a 102(e) novelty objection, but then notices that A has the earlier priority filing date, on the same invention.

    My opinion? Once he’s established the validity of A’s priority, he should probably do nothing, other than issuing a notice of allowance. In an ideal world, B’s application gets flagged so that the examiner in that case requires a new claim to provoke an interference (under 37 CFR 41.202) and/or demands evidence of priority to beat A’s already established priority date. If B wants to fight it out and comply, then we have an interference. If B knows he’s going to lose, he can concede and all this messiness is avoided.

  21. 155

    As noted below, I doubt Ping is Patent Hawk.

    It would “bring the chuckles” though if Ping’s absence is because Patent Hawk has retained Ping…

  22. 154

    Mine at 4:50 was posted without seeing Cy’s at 5:05.

    I think I see now. The PTO ought not to give A a patent without first finding out if B invented first.

    Given that interferences are almost as rare as hens’ teeth, I think I now see the teeth in Ned’s earlier question to Cy. What indeed should the Examiner do, who is examining A’s PTO filing, finds himself looking at B’s earlier USPTO filing on the same invention, thinks about a 102(e) novelty objection, but then notices that A has the earlier priority filing date, on the same invention.

    Come to think of it, when did 6 last check in? And is Malcolm Mooney interested enough to chip in?

  23. 153

    Ned, Cy, please help me here because I’m still confused.

    With my scenario, I had tried to shut out all extraneous complications like “diligence”. Thus, the stimulus for the act of conception comes from a Paper read at a conference just a few days before A and B file their respective enabling disclosures on substantially the SAME INVENTION. This is NOT, by the way, a rare event.

    Perhaps I should have included an extra fact, that the respective filings of both Herr Dr A and Frau Dr B at the USPTO contain nothing additional to the technical and legal content of the respective German national priority filings.

    Now, Ned, at 4:19pm, you tell me that the PTO cannot issue Herr A with a patent, even though he was first to conceive, diligent, first to reduce to practice and first, under Paris, to file. Why is that then?

    Cy, your advice was, I had thought, precisely the opposite from what Ned advises. Are you standing by that advice, or do you now want to recant?

    And where, BTW, is anonymous in all of this?

  24. 152

    I am not paid to know US patent law. Learning about it on this blog is a hobby of mine.

    I would suggest a more rigorous learning experience. Learning from a blog such as this, you are bound to learn the wrong things more often than not. You will then have to unlearn positions you should not have learned in the first place.

    Even for a hobby – if this is related to your vocation, you deserve better.

  25. 151

    …the PTO cannot issue him the patent, can it?

    Ned, I think you sometimes get “cannot” and “preferably should not” confused. I’ve certainly seen the PTO issue multiple patents covering the same essential subject matter. This issue doesn’t arise only in the case where foreign priorities are involved.

    Of course, the chances of two applicants submitting identical claims are pretty slim, unless something very unusual is going on. I appreciate that PTO examiners can provoke an interference where claims are very similar. But it’s clearly impractical to expect the PTO to seek out potential interference contests. It’s an infrequent enough occurence that it’s just not worth it. Besides, there’s not much harm to the public, is there? If the applicants don’t notice while the patents are pending, then let them fight it out later in court, if either still cares.

  26. 150

    Cy, if A is overcoming art that is not disclosing and claiming the same invention, the assertion of his priority date should be sufficient for him to get the patent without further ado.

    But if he is claiming the same invention both disclosed and claimed in the reference, the PTO cannot issue him the patent, can it?

  27. 148

    Sorry, Ned, I really thought you were changing the scenario. You’re more than a bit difficult to keep up with, at times.

  28. 147

    No offense meant, Ned. A rejection under 102(e) simply wouldn’t be appropriate, given the priority claims. I don’t pretend to be an expert on interference practice, but I believe there are circumstances under which an examiner can provoke an interference, but that gets you way out of the realm of 102(e). I believe the examiner can also require an applicant to prove that he has a priority date earlier than his priority filing, but that applies only when somebody else’s apparent date for constructive reduction-to-practice is earlier than the application at issue. That wouldn’t apply to A.

    As far as I can tell, A should have no problems here, having the apparent earliest priority, until and unless an interference is provoked from the B application. Right? Wrong?

  29. 146

    Max, the problem is that both applications are disclosing and claiming the same invention and neither is a statutory bar to the other. Under any scenario, these two applications will have to be thrown into an interference where the party having the earlier filing date is, on motion, granted senior party status.

    But that does not end it. Both parties have the right to prove prior invention dates. Here, A wins as well everything else being equal, as he was the first to conceive and I presume, given the facts, was diligent to filing an application in Germany.

    But that depends upon proof of earlier conception and diligence, which is not a piece of cake. So, solely based on the facts disclosed here, the answer is not determinable.

  30. 144

    Cy, w t f are “you” talking about then?

    The facts are that in the A application the examiner rejects over B. You said, that A can overcome the rejection by relying on his priority date.

    I simply pointed out that he cannot given all the other facts here in that the two patent applications are disclosing and claiming the same invention.

  31. 142

    I don’t know what you’re talking about, Ned. I thought we agreed that in Max’s scenario, there is no rejection. Are you changing the story so that A does not claim priority to his German application? If so, then I’ll take your word for it.

  32. 141

    I thought it all so simple, and reassuring. Presented with the priority date claimed by A, earlier than B’s 102 (e) date, PTO Examiner immediately issues A with a patent, for being the First to Invent. But Ned says not. Yet again, I don’t understand. Help.

  33. 140

    He cannot accept the proffer in either case, lest he allow a second patent on the same invention. He must deny the request, and suggest an interference where the issue of support in the priority document will be the first issued decided. If there is support, A is accorded senior party status.

    In either case, the party who wins normally is the senior party. But, given the facts here, either A or B might win. It depends upon who can prove prior conception.

  34. 139

    Sorry, Ned, but I find your “Socratic” method to be tiresome. If you’ve got something intelligent to say, then out with it.

  35. 138

    Ned, I read Cy and thought “That settles it. I am all wet. Many thanks Cy.”. But then you posed your question, Ned, and it surprised me. What’s the answer Cy (or Ned)?

  36. 137

    Max, one of the problems the new statute is trying to fix is the Hilmer “problem” for non US inventions. Harmonization, after all, is all about giving equal rights to non US inventions. Smoothes international business, and all that. Removes roadblocks caused by two patents on the same invention held by two different entities in two different countries. Real problem for international businesses.

  37. 136

    I am not paid to know US patent law. Learning about it on this blog is a hobby of mine. Generally, I find it effective to be provocative (as in this thread).

    As for tools, they are reckoned to be useful things. I like to think that my US corporate clients find me a useful tool, when it comes to unlocking issues in Europe. I am convinced that the experience I am gaining on this blog makes me ever more effective. And you? Are you a tool too?

  38. 135

    Cy,

    1) Assume A relies on his prior invention by referencing his priority application, what is the examiner supposed to do next in the A prosecution?

    2) Clue, assume A files a Rule 1.131 affidavit, relying on his disclosure in his prior application as a constructive reduction to practice and with his earlier conception in Germany?

    Should what the examiner does be different?

  39. 133

    I tried “Hilmer Doctrine” in Wikipedia. Null result. So then I Googled it and found Kate Murashige’s 1993 John Marshall Law Review paper.

    Only now you are actually researching the “Hilmer Doctrine”, after all your “wet noodle” proclamations?

    What a tool.

  40. 132

    A’s application is finally rejected under 35USC102(e) and duly lapses.

    I don’t think that’s right, Max, assuming A properly claimed priority to the German application. The 102(e) date for B’s published application is it’s actual filing date in the U.S., which is well after the priority date for A’s application.

    Look very carefully at the language of 102(e)(1). It compares the filing date, in the U.S., of the reference document, to the date of invention for the application at issue. Herr Dr. A gets full credit for his Paris date here – indeed, he could even get an earlier date if he could show reduction to practice before the German filing.

    Unless I’m missing something, if this is the basis of your complaint about 102(e), then you’re all wet.

  41. 131

    Stung by “anonymous” in the “Responding…” thread, I tried “Hilmer Doctrine” in Wikipedia. Null result. So then I Googled it and found Kate Murashige’s 1993 John Marshall Law Review paper.

    Consider two inventors in Germany, Herr Dr. A and Frau Dr. B. They both attend a key presentation at an intermational medical devices conference. While listening, A conceives an invention.

    A week later, Frau B is explaining to a colleague what she heard at the conference the previous week. That prompts her to conceive the same invention as A conceived, a week earlier.

    Independently of each other, both write an enabling disclosure, which is then professionally and competently polished by their respective patent attorneys. Each files, independently of the other, at the German Patent Office, in German, exactly two weeks after their respective acts of conception.

    Near the end of the Paris priority year, B’s patent attorney is going on a long vacation (as German patent attorneys do, don’t you know). This is to the great good fortune of B, because her patent attorney acts in advance, and gets her order letter away much earlier than A does, to the patent firm in the USA who will file at the USPTO. Under 102(e), B’s early US filing denies A any patent rights in the USA, even though A was first to invent and first to file. A’s application is finally rejected under 35USC102(e) and duly lapses.

    Can B (second to invent, and second to file) still get a patent in the USA? What stands in the way?

    I understand that in any enactment of the Senate version of 102, Hilmer becomes moot. But when? At least twenty more years of the Hilmer Doctrine, I suppose.

    I am A. Under the Paris Convention, by virtue of my “first filing in a Paris Convention country” I enjoy a “right of priority”, also in the USA. In other words, I am entitled to deference. 35USC102(e) deprives me of the deference that is my right. I was prior to B in conception, reduction to practice and filing at a Paris Convention patent office. But nevertheless, I get no patent in the USA. If anybody does, it is B, who invented later than me, reduced to practice later than me, and filed her first application for patent protection later than me. No wonder Jones Day characterizes the Hilmer Doctrine as “infamous”.

  42. 130

    Ned, there is no dispute that your 102(e) date depends on where you file the application that gives you the 102(e) date that your USPTO publication exhibits. So far so good.

    Now you and others say that the prior art effect of a publication by the USPTO is not governed by the Paris Convention. OK, I see the point but think (for the following reason) it is irrelevant.

    You ask: “Explain to me, Max, how this is in any way different from the way it works in Europe where the first filed application cannot be used for inventive step purposes against second filed applications?” I will explain.

    Article 54(3) EPC is the tool for deciding, between rival Applicants at the EPO for the very same invention, who gets the European patent ie a priority contest. You have to have two rival cases both at the EPO before you have a contest. But, in any such contest, the country each contestant comes from is not a factor.

    So too, nowadays, with interference contests in your country (but you are old enough to remember when that was not the case, and inventor logbooks from ROW were of no effect).

    You (thinking all the time of 103 issues) categorize 102(e) as prior art and decide priority on a First to Invent basis. I (looking through my 102 spectacles) see it as a tool for deciding in a First to File jurisdiction…wait for it… priority.

    So, Ned, summing up, I expect, once the USA moves to First Inventor to FILE (as opposed to INVENT), there will be fresh impetus to bring Hilmer doctrine come up for scrutiny at the WTC.

    Thanks to you and everybody else who has been trying so hard to educate me.

  43. 129

    Many thanks Ned for “It is high time we Americans stopped apologizing for Hilmer”.

    Methinks some people in the thread above are like the lady in Shakespeare that “doth protest too much” but that’s just my wishful thinking.

    Let’s “move on”, shall we?

  44. 128

    The sense of Paris is that a filing in one country shall have the same priority effect as the filing of the same disclosure at the Patent Office of any other Convention country

    No it does not.

    You never answered my earlier post, So I reprint it here:

    “Patrick Henry said in reply to MaxDrei…
    too…?

    The rights are what exactly in each country? Or do you think it possible for a country to give rights in that country that are not actually available?

    Do you know what sovereignty means?
    Reply May 15, 2011 at 05:19 PM ”

    A country cannot give rights within its borders that it does not have.

    Simply impossible.

    Your sense of “Universalism” betrays your lack of understanding of sovereignty.

    You are chasing an issue that does not exist.

  45. 127

    Max, what I find utterly remarkable in your thinking is this:

    That the meaning and effect of priority changes depending upon country of claimed benefit.

    Anybody landing on this planet for the first time would sincerely question the whole concept that the meaning of the term would vary by country of effect.

    Priority is priority. It has a well understood meaning. It has nothing to do with prior art. Nothing. Nada. Nil. It has nothing to do with inventive step. It has nothing to do with obviousness. It merely gives a right of priority to a claimed invention to the first filer of a patent application.

    Now the right of priority also does not tell anyone that the disclosure of a patent application must be given effect regardless of national requirements of utility, of written description, of enablement, of best mode, of the presence or claims, etc. The right of priority does not require mininum or maximum treatment of these issues. The right of priority says nothing about them.

    The right of priority additionally says nothing about whether the patent application can defeat subsequent filings by others of different inventions. Nothing at all. But that is the very right you guys in Europe are claiming by asserting that patents have prior art effect as of their foreign priority dates.

    This is all just a bit much, Max. You think we discriminate when we do not. Your accusations are wrong and have been wrong since the days of Hilmer. It is high time we Americans stopped apologizing for Hilmer and stopped trying to fix it with “reform” legislation. There is nothing wrong with Hilmer at all.

    Even wise folk note that if we go to FTF, we need to limit the effect of patent applications to novelty only effects. But that is the effect we give patents today as of their foreign priority dates. The real problem, if anything, is the use of any patents to be effective from their filing dates for Section 103 purposes. That, my kind friends, was a serious mistake. If we fix anything, let’s fix that.

  46. 126

    Cy writes of the Paris Convention “It doesn’t say anything about the effect of your priority filings on other applicants. ”

    Hooray. Now we are on point. swords and shields, as I said earlier. I say that Paris Art 4 establishes ” right of priority” simpliciter. Cy then “cabins and confines” (to use an expression beloved of another frequent contributer) that priority right, to neuter the priority effect under 102(e), when the priority filing is at any other than the US PTO.

    The sense of Paris is that a filing in one country shall have the same priority effect as the filing of the same disclosure at the Patent Office of any other Convention country. Hilmer denies that priority right.

    Hilmer has been debated for decades, using the swords and shields argument now acknowledged by CyNical. I was just curious to see what contributers here had to say on the issue. I know that now.

  47. 124

    I am a bit too subtle for this crowd.

    The root word you’re looking for is “wave,” not “waive.”

    No, that would miss my pun on “waive”, as in:

    1. to refrain from claiming or insisting on; give up; forgo: to waive one’s right; to waive one’s rank; to waive honors.

    2. Law . to relinquish (a known right, interest, etc.) intentionally.

    MaxDrei has intentionally not answered my argument and insists on going around in circles, only too happy to note that he is going around in circles.

    Perhaps on the third go-around we will see an answer from MaxDrei.

  48. 122

    Max, what they understand is that one needs to

    1) Publish the foreign application on filing.
    2) File PCT, but publish in English.
    3) File a US provisional.

    to obtain full prior art effect. Now that is an entirely difference kettle of fish entire than whether the US is in violation of the Paris Convention.

  49. 121

    Max, 102(e) is the prior art date of a reference. As such, the reference itself is combinable with other references under Section 102.

    However, and I have attempted to patiently explain to you the difference, the priority date prevents others from obtaining a patent on the same invention if their own priority date (including invention dates) is later. All priority dates are treated the same regardless of origin. There is no discrimination. The Paris Convention does not require that patent applications be treated for full inventive step purposes against other patents as of their priority dates, now does it? The US is in full compliance with the Paris Convention.

  50. 119

    Brilliant answer Cy. I laughed out loud. As to the rest, I’m bored. The Hilmer 102(e) issue has troubled for years those who file their priority application in a language other than English and then enter the USPTO (and the JPO and the EPO and the China) at the end of the Paris year. Those US patent law firms who routinely act for alien applicants understand the issue, even if some here don’t.

  51. 118

    Paris did not set out to make everybody file on their first prio date in every language under the sun. Or did it Minds?

    Paris also did not set out to define the scope of the prior art. This is precisely where you’re off track with the Paris argument. Paris defines

      your

    right of priority, with respect to getting the claims that you ask for in your various national applications, in the face of your own later acts or acts by others. It doesn’t say anything about the effect of your priority filings on other applicants. There is no symmetry requirement in Paris.

  52. 117

    Either “hand-waiving” or “handwaiving,” please stop and address the substance of Article 2.

    Uh, I think you might have missed Max’s point. The root word you’re looking for is “wave,” not “waive.” Hand-waiving is what you’re doing when you steal something very valuable in certain very strict, fundamentalist communities.

  53. 116

    Talk about being pedantic:

    Either “hand-waiving” or “handwaiving,” please stop and address the substance of Article 2.

  54. 115

    Ned, you write: “They should never allow the patent having the earlier US filing date to issue in the face of another application disclosing the same invention that has an earlier foreign priority date”. I agree. But what is the 102(e) date if that foreign filing date comes into the USPTO as the national phase of a PCT filed in a language other than English? You think it is the foreign prio date and I think it is the date of arrival of the English language text in the USPTO.

    Henry Ford, and Henry Hilmer: any language you like, as long as it’s Chinese, oops, English.

    Paris did not set out to make everybody file on their first prio date in every language under the sun. Or did it Minds?

    BTW, does everybody in the USA spell “hand-waving” as “handwaiving”? or is it only ping and Minds?

  55. 113

    Usually when there’s complaining about “discrimination” in the context of Paris, the issue is Article 2, which is of course about national treatment. I see elsewhere in the thread that you’re not talking about Article 2. If that’s the case, then I suggest that “discrimination” is a poor way to describe your complaint – other than the Article 2 and 3 requirements with regard to national treatment, I don’t think Paris prohibits discrimination between differently situated persons or applications.

  56. 112

    Article 4, section B, spells out precisely what the “right of priority” means. Which aspect of Article 4 does 102(e) violate?

  57. 111

    MaxDrei,

    It was I that introduced Art 2.

    You are handwaiving that Article away and merely proclaiming that it is not relevant. This is your critical error, and this is precisly why we are “repeating ourselves endlessly.” We do not need anyone else – we need you to stop handwaiving something away merely because it does not fit your argument. It is as simple as that. Perhaps you can show your reasoning for dismissing the part of the Paris Convention and we can make some progress in our discussion rather than repeat ourselves.

    Once again as I said above: the ball is in your court.

  58. 110

    Max, there is no discrimination regardless of how much you attempt to create an issue. Paris Convention requires priority be accorded and it requires there be no discrimination. There is none.

    Events taking place solely in the US are another matter and are of domestic concern only. The statutes lay them out. Knowledge, on sale, use, invention all have to be in the US. These are the elements of prior art.

    A US patent is prior art as of its filing date in the US. This is consistent with domestic prior art law, not inconsistent.

    On the other hand, the first to file will and should obtain the patent. To the extent that the PTO does not search foreign applications for same invention type “prior art,” they are derelict in their duties, IMHO. They should never allow two patents to issue on the same invention. They should never allow the patent having the earlier US filing date to issue in the face of another application disclosing the same invention that has an earlier foreign priority date.

    The problem is not with the US laws, but with the PTO.

  59. 109

    It it Paris Article 4, the positive “right of priority” I am constantly citing. I think Paris means here what it says here. Somebody else above introduced Art 2 of Paris, I think it is not relevant. Of course you must file a translation of the priority document. In Europe we know all about different languages for different countries.

  60. 108

    Thanks Cy. Much appreciated. But it was news to me that Paris is all about nationality. Where do you derive that from then?

    As you say, few if any within the USA see Hilmer as violating Paris. But wait till another country implements Hilmer. Then see how much the USA likes being done by as it does to others.

    The Golden Rule used to be “Do as you would be done by” but in its more modern form it goes “Don’t do to others what you would not like them to do to you”.

  61. 107

    People outside the USA think that the Hilmer interpretation of 35 USC 102(e) discriminates against everybody who creates priority dates at Patent Offices other than the USPTO. What if every other country behaved like the USA? It defeats the purpose of the Paris Convention.

    Even if everything in your comment is correct, I still don’t see any actual violation of the Paris Convention. Article 2 doesn’t prohibit discrimination based on how or where the priority document was filed. It prohibits discrimation against foreign nationals. Because the German applicant is treated just like a US applicant with respect to 102(e), there is no violation.

    If you’ve got a problem with Hilmer, you’re not going to fix it via Paris.

  62. 106

    Max, you’re going to have to understand that even Americans do not fully agree that a patent should be “prior art” as of its filing date. As you, and others perhaps, have pointed out, even Europe does not consider patents to have a full prior art effect as of their filing dates.

    The theory that the United States patent application is prior art as of its filing date is that, but for the delays of the patent office, they could have issued in the United States on the day they were filed. Obviously, this cannot be true until one actually files a patent application in the United States Patent Office. Therefore the very theory upon which patent applications are prior art does not exist for foreign applications.

    On the other hand, for its entire history the filing of US patent application has given the owner of the patent application “priority.” This priority helps determine which of two rival applicants to the same invention should be accorded the patent.

    Because United States gives foreign-filed patent applications priority effective to the same extent priority is effective for a United States patent application, there is no discrimination. The first-to-file gets the patent to the invention, absent proof of prior invention by the second applicant.

    What you have why seem to misunderstand is that your priority reserves for the non-US application the right to obtain a patent to the disclosed and claimed invention over earlier-filed United States patent applications. From my understanding of European law, this is exactly what the European law also gives the first-filer in Europe.

    If you want more, if you want your patent application to be prior art in the United States, published it on the date it is filed in Europe. Perhaps you folks could develop something as strenuous as a checkmark on a form that would waive all privacy on a European patent application allowing it to be considered laid open the day it was filed. This would make the European patent application prior art in the United States on the day it was filed in Europe regardless of the language.

    And as you note, you can always file that European application in the United States as a provisional if you want later §102(e) effect.

  63. 105

    Minds, you and I are repeating ourselves endlessly. We need help from another, perhaps IANAE. It is well-known that a 102(e) blocking effect on the later filings of your competitor at the USPTO can arise from your own earlier filings at the USPTO but NOT if you arive in the USPTO at the end of the Paris year declaring priority, and your earlier filing event (earlier than the other fellow) is in another language at another Patent Office.

    People outside the USA think that the Hilmer interpretation of 35 USC 102(e) discriminates against everybody who creates priority dates at Patent Offices other than the USPTO. What if every other country behaved like the USA? It defeats the purpose of the Paris Convention.

    Ned Heller says “What are you whingeing about. You can set up an interference”. Doesn’t cure the discrimination though, does it Ned?

  64. 104

    MaxDrei,

    I have already replied to your point, and further asked you to provide some specificity to your claim that the Hilmer doctrine violates the participation of the US in the Paris Union.

    The ball is in your court to do more than merely say that it violates.

    I believe that my Article 2 comment quashes your generic Article 4 comment. The club of Paris only means that you have to play by each members’ home rules. Everyone has to play by the Hilmer doctrine – no exceptions. I just do not see the wrong you claim. Please help.

  65. 103

    Would Ned Heller or Enquiring Minds care to reply to my point, that the USA (by the Hilmer Doctrine) is in breach of the provisions of the Paris Convention? I am curious to have a reasoned reconciliation of Hilmer and membership of the Paris Union.

  66. 102

    Fly and I are going on about what 102(e) date one gets, to block the progress that one’s later-filing competitors are making, through the USPTO, to issue. Hilmer says, it depends where you file your priority filing, what 102(e) date you get.

    It is the swords and shields point, Ned. Fly and I say Paris applies to both, but Hilmer says it only works for swords. Why that then?

  67. 101

    But if you sign up to Paris you agree to give to a German filing in Germany the same rights as if he had filed instead at the USPTO, in English.

    That’s not at all what Article 2 says. Article 2 says that US law has to treat a German national at least as well as it treats US nationals. Interestingly, it is allowed to give German nationals more favorable treatment, but not less.

    Your identified “discrimination agains those who rely on a priority date not at the USPTO” is not based on the nationality of the applicant, even if it tends to impact foreigners more than US nationals. You might note that inventors in the US aren’t allowed to file a priority document abroad without first getting a foreign filing license. Unfair? Maybe, but life isn’t fair.

  68. 100

    Oh I agree – “slinging” is something the Hawk enjoys (still).

    But to be pedantic, I did say “wrestle,” not sling.

  69. 99

    Max, there is no discrimination in the law. To the extent that the USPTO would not recognize the earlier priority claim of a later filed US application and actually issue a first filed US application to the same invention is, to me, fundamentally wrong and a violation of the treaty.

    If the commissioner thinks his hands are tied, I think he needs to simply rely on the earlier priority date and reject the later-filed US case on Section 101 grounds, since he cannot rely on 102(g).

  70. 98

    Max, your assumptions remain incorrect. The first filer regardless of jurisdiction still gets the claims to the invention because he has priority. This does not depend upon the first filer’s application being “prior art” for Section 103 purposes.

    Explain to me, Max, how this is in any way different from the way it works in Europe where the first filed application cannot be used for inventive step purposes against second filed applications?

  71. 96

    My point is that when you claim priority from a filing at the USPTO you get that priority date for the prior art effect your app has on that of the other fellow. But if you declare priority from a filing at any other PTO, you don’t.

    So if you are, say, Ericsson and you need an early 102(e) date, to block later Motorola applications at the USPTO, on the same subject matter, better create Ericsson Inc and file your priority documents in English at the USPTO (rather than in Swedish at the home Patent Office). Why should every foreign corporation have to do that?

    Hilmer offends Paris. But, hey. So what. Who cares?

  72. 95

    Patent Hawk sure didn’t have any problem with slinging mud at prosecutors and litigators. He’s not as clean as he likes to pretend he is.

  73. 94

    Yes, of course one has to play by the rules that apply on the playing field on which you play. But if you sign up to Paris you agree to give to a German filing in Germany the same rights as if he had filed instead at the USPTO, in English.

    Ned, did the Hilmer court justify its discrimination against those who rely on a priority date not at the USPTO? Language? Art 2 Paris? I think not.

  74. 93

    He’s probably busy writing amicus briefs on behalf of all the citizens of the United States of America.

  75. 92

    I would verily doubt that Ping and Patent Hawk are the same. Patent Hawk could not stand to wrestle in the mud – Ping lives for it.

  76. 91

    Max, What I am saying is quite a bit difference and has nothing to do with provisional applications.

    Let’s take it step by step.

    A resident of Germany files in German in German. Within the year, he files Paris Convention in the US.

    Before his US filing date, an American files in the US, disclosing and claiming the same invention.

    The German’s patent application/patent is not prior art under Hilmer I or II. Even so, the US first filer still cannot obtain a patent on the same invention being claimed by the German because the German has priority if the German requests an interference. When the US application reaches the allowance stage, the examiner conducts an interference search. It is there the priority German patent/application is revealed. The examiner then offers the US applicant, the German applicant, or both of them the opportunity to request an interference.

    If neither agrees however, the PTO is in a bind. They should not issue the patent to the American filer who is second in priority, but that is probably what they will do in practice. The problem is of course, caused by Hilmer II.

    Now, once the patent has issued to the American, the German can still request an interference and be accorded senior party status due to his foreign priority date. But, one might argue that having been given the chance to request an interference earlier, he might be estopped to do so now.

  77. 90

    MaxDrei,

    What part of “translations in due course” did you miss from Roufousse T. Fairfly’s comments above?

    All that I am saying – and for some reason you do not want to grasp this – is that I fail to see where the problem is. You have to play by the home country’s rules. As does everyone else. If language is one of those rules, then this seems to be entirely fair.

    Does my suggestion that Article 2 not provide for this? Can you explain this part of the letter (and spirit) of Paris? I eagerly await your tutelage.

  78. 89

    Ned, Minds, you seem to be saying that a USPTO publication can have a 102(e) effect as of its priority date under the Paris Convention, but only if the priority filing in the Patent Office of, say, Germany, Japan or China, is filed in the English language. Are you filing your US provisionals in German, Japanese and Chinese as well as in English? Is that what you advise your clients do do (the counterpart to the advice European patent attorneys feel compelled to give their clients: file their priority document simultaneously in English at the USPTO) if they want a full and fair 102(e) effect in those countries. See Fairfly way up above.

    Is that right? Is that the spirit of Paris? Do I understand you right? Are you serious?

  79. 88

    Malcolm, you equate ping’s lack of positing with being the Patent Hawk? Or do you know it to be the case from other info?

  80. 87

    I know.

    The PC requires that priority be given. It is. What more can one ask?

    If a later applicant files for the same invention, they cannot claim the same subject matter unless they wish to be thrown into an interference with the foreign priority application being senior party. In effect, the priority prevents others from later disclosing and patenting the same invention.

    Now how is this different from the EPC?

    The problem I see that a member of the public has no right to demand the PTO to declare an interference between two patents on the same invention. So if the PTO does in fact issue two such patents, the public has no recourse except to pay both a royalty. I think that wrong.

  81. 85

    I guess ping Patent Hawk is too busy to comment here in the wake of the invalidation of his patent.

  82. 84

    My faux pas – but now back on track.

    Wouldn’t Article 2 be on point though in regards to language requirements?

    “Consequently, they shall have the same protection as the latter, and the same legal remedy against any infringement of their rights, provided that the conditions and formalities imposed upon nationals are complied with.”

    As Ned Heller indicates – requiring English is merely playing by the national country’s (here US) rules. It applies to everyone, so I am still not seeing the source of complaint. It is not as if you follow the home rule syou do not get priority if you are not a US citizen – you just have to follow the rules. No different than anyone else.

    Or am I still missing something?

  83. 83

    PCT = Patent Cooperation Treaty, dating from 1978

    The Paris Convention dates from the 1880’s. You do not need to add “Treaty” to “Convention”. You can have the Rome Treaty, that set up the EU. You can have the European Patent Convention, that set up the EPO, but you can’t have the Paris Convention Treaty. Got it now?

    Ned I’m talking about what Fairfly is on about, namely, Paris and Hilmer. OK?

  84. 81

    All, the problem we have with Hilmer II is that it is assumed the PTO will catch interfering patent applications before they issue and declare an interference. After they issue, it is not clear that the second filed patent claiming the same invention is invalid. One could cite the first filed patent in a reexamination, but what could the PTO do? It cannot declare an interference. Ditto in the upcoming new opposition procedures.

    What we need is for the patent owner to be able to request an interference before the second patent on the same invention actually issues. This is a gaping hole in our laws and rules.

  85. 80

    Max, I explained this to you some time ago. The foreign filed document has patent defeating effect as of its filing date for that which it discloses and claims.

    That is the effect you give patent applications in Europe, so where is the discrimination?

  86. 76

    Fairfly, really?

    The non US or non English language PCT will still have a priority date that guarantees that no later filed patent can claim the same invention.

    Now, isn’t this the same as in Europe, not different?

    Europe does not offer patent applications inventive step effect from their filing dates. We do not offer that as well to them. Where is the discrimination.

    What we offer is that all American patent applications will be treated as having inventive step effect while all non American patent application will be offered the full benefit of their priority dates. Is more required?

    Where is the discrimination?

  87. 74

    In haste, Minds, check on the text of Article 4 of the Paris Convention “shall enjoy, for the purpose of filing in other countries, a right of priority”.

    But I get “a right of priority” in the USA only if I file at the USPTO.

    It is this which bugs our friend Roufousse Fairfly.

  88. 72

    Well, Minds, I think it is Article 4(c). Whatever, it is the one that says what i wrote above, that you get a priority right (against other Applicants) which is as effective when the priority filing is in the Paris country of first filing as when it is in the country where the priority contest is taking place.

    Are you going to give me the Hilmer stuff about swords and shields? if so, please tell me what basis there is for it, outside the US court that handed down the Hilmer ruling.

    Thuis is why Roufousse Fairfly mentions the spirit of Paris as well as its letter. I never did understand the Hilmer logic. I’m enquiring now. Will you help me?

  89. 71

    either adhere to club rules

    Which club rules were broken?

    Which club rules would Hilmer not be in accord with?

    What rights (per Patrick Henry) are not being followed/created when they do not exist?

  90. 70

    I think so. And I also think if a country joins a club it should either adhere to club rules or leave the club. These days though, membership of the WTC affords a route to resolve a dispute, whether the USA is following Paris rules. There has long been an open question whether Hilmer is in accordance with Paris rules.

  91. 69

    too…?

    The rights are what exactly in each country? Or do you think it possible for a country to give rights in that country that are not actually available?

    Do you know what sovereignty means?

  92. 68

    The spirit of the Paris Convention is reciprocal rights, whereby each can first file in his or her home country and, provided foreigns are filed within the specified period thereafter, get rights in those foreign countries just as if he (or she) had filed simultaneously all over the world.

    Or have I got that wrong too, Mr Henry?

  93. 67

    All that is not really necessary, and defeats the spirit of the Paris Union, if not the letter.

    But does it?

    Is the spirit of the Paris Union an acquiesence of individual State sovereignty?

    I think not.

  94. 66

    Thanks Babble but I was thinking about 103 after A publication of a 102(e) document. Subject matter it fails to enable might still provide an effective 103 attack on a claim that was filed after the 103 reference (but not under the EPC).

    Sorry if we are talking across each other. It is Sunday today.

  95. 65

    Fly, well said. I can recommend the book “Invisible Gold in Asia” by the distinguished IPR jurist Llewelyn. See the warning on page 40, that the USA is an exceptional jurisdiction, unlike any other. Imagine the outcry in the USA, if any other country were to adopt the old Henry Form maxim “You can have any color you like, as long as it’s black” and say to the Applicant from the USA “To get your priority effect here, you can file in any Paris Convention country you like, just as long as it’s ours”.

  96. 64

    Not sure I’m seeing the train wreck, Max.

    Anything filed under FtF — provisional or non-provisional — in US that does not meet 112 requirements does not afford any priority to the guy who fell all over himself to get to the patent office. But even so, if published, it would be valid prior art against others for what it does teach. So what’s new?

    Note it is a publication that triggers 102(e). An application that is not published is not 102(e)-compliant unless it issues as a patent and is then published. So there is always this 18 month period of “secrecy” between the inventor and the patent office. Isn’t that true for EPO?

    And the application must be filed by another. If you file your own inadequate application, it cannot be used as 102(e) PA against your later filed applications, but it can be used against anyone else even if it is not sufficient disclosure to get issued.

    The “self-collision” you refer to would be as a result of 102(b), not 102(e).

    And I don’t see how FtF would change any of this in the US.

    My guess is that 90% of inventors are relying on constructive reduction to practice and so they are rushing to the PTO anyway without fully formed ideas thereby deceiving themselves — or being deceived by their lawyers — that they are filing a priority document.

  97. 62

    First, because a patent application will be considered prior art as of the date of filing (once published or patented) under 35 U.S.C. 102(e), the company can establish a prior art priority date without actually publicly disclosing the invention for at least 18 months.

    Dennis, a mention the Hilmer doctrine and language requirements should be made, which in practice force foreign applicants to file early in the English language in the US if they want to obtain recognition under 102(e).

    Sure, you can resort to the trick of simultaneously filing a US provisional in the foreign language, file a PCT in English one year later, and eventually provide a translation of the prio document . All that is not really necessary, and defeats the spirit of the Paris Union, if not the letter.

    I won’t don a Mao suit and wave the little blue book, but I must state that this question is addressed differently abroad, and not only in EPC-land.

  98. 61

    Again and again this blog attracts sockpuppets who can’t articulate themselves out of a wet paper bag.

    the MPEP specifically states “[t]he examiner of the continuing application will consider information which has been considered by the Office in the parent application.” See MPEP 609.02.

    Sxck it, Yoda.

  99. 60

    Parse, we do seem to agree that what MS did later in filing its own patent application on the same invention seem well tangential wrt any obviousness issue.

    I’m not so sure that Dennis may not have been influence in the wrong direction by Odom. I’d actually have to read the upper and lower court materials to get a real sense of what happened in this case.

    Back to the estoppel issue, you are right that I know of no case directly on point save potentially this case. It would be interesting to see whether the issue was properly raised by Odom and whether the district court addressed the issue at all.

  100. 59

    This fits perfectly with the definition I’ve been using. But this is besides the point.

    The question is whether or not estoppel applies in this case (estoppel is not automatic). So far the case law I’ve seen are for fact patterns that are materially different from the one we have here. And, I have yet to see a persuasive argument (since we don’t have a direct case on point) for why it should apply in the fact pattern I laid out.

    To the extent that my fact pattern matches the fact pattern in the MS case, and to the extent Odom tried to make an argument as to why estoppel should apply, I think the court got it right. You, on the other hand, think otherwise.

    Dennis’s point was that if the issue was obviousness, things might have been different, and specifically because of KSR. And I have not seen a persuasive argument to that effect.

  101. 58

    And you know that the Examiner didn’t consider the references in the parent because …

    Immaterial, your question is. Matter not it does.

    Again and again – look to the rule that must be followed in order to apply the references from the parent (to the child):

    Again and again – ask yourself, was the rule followed here?

    Answer again – rule was not.

    No presumption earned (to the child).

    Actually, I meant in this sense:

    ESTOPPEL, pleading. An estoppel is a preclusion, in law, which prevents a man from alleging or denying a fact, in consequence o his own previous act, allegation or denial of a contrary tenor. Steph. Pl. 239. Lord Coke says, “an estoppel is, when a man is concluded by his own act or acceptance, to say the truth.” Co. Litt. 352, a. And Blackstone defines “an estoppel to be a special plea in bar, which happens where a man has done some act, or executed some deed, which estops or precludes him from averring any thing to the contrary. 3 Cora. 308. Estoppels are odious in law; 1 Serg. & R. 444; they are not admitted in equity against the truth. Id. 442. Nor can jurors be estopped from saying the truth, because they are sworn to do so, although they are estopped from finding against the admission of the parties in their pleadings. 2 Rep. 4; Salk. 276; B. N. P. 298; 2 Barn. & Ald. 662; Angel on Water Courses, 228-9. See Co. Litt. 352, a, b, 351, a. notes.
    2. An estoppel may, arise either from matter of record; from the deed of the party; or from matter in Pays; that is, matter of fact.
    3. Thus, any confession or admission made in pleading, in a court of record, whether it be express, or implied from pleading over without a traverse, will forever preclude the party from afterwards contesting the same fact in any subsequent suit with his adversary. Com. Dig. Estoppel, A 1. This is an estoppel by matter of record.

    Assuming the facts are as I’ve read in the post and comments (because I’m too lazy to ready the case), maybe MS should have been estopped, Ned. Or alternatively, maybe that just means MS’s later patent should be invalid for IQ. MS might rather have the latter (so it doesn’t have to pay out $$).

  104. 55

    Parse, equitable estoppel relates to false statements.

    Statements don’t have to be false for equitable estoppel to apply.

    Legal estoppel prevents you from changing your position at all.

    The whole point of any kind of estoppel is to prevent a party from changing its position.

    If you are using the phrase “legal estoppel” as a term of art, then I believe it only applies to the assignor-assignee situation as I mentioned earlier.

    See link to en.wikipedia.org.

  105. 54

    Parse, equitable estoppel relates to false statements. Legal estoppel prevents you from changing your position at all.

    The real question here is whether there is an estoppel and its scope. That would depend upon what was said in the prosecution of the Kavalam application, and whether the later MS patent application disclosed and claimed (at least on filing) the same invention patented by Odom. If it was different, perhaps the differences were material, perhaps they were not.

    But those are the issues that normally need to be resolved in litigation.

    What apparently happened here is that both the DC and the Feds refused even to consider the arguments. I don’t know why, as I haven’t actually read the opinions of the DC or the Fed. Cir., and am only relying on Dennis’s summary, but it strikes me that the decisions should have come out the other way based on my understanding of the law.

  106. 53

    Dennis, I disagree with your contention that the Federal Circuit ruling implies a presumption that the reference wasn’t considered. They didn’t address the issue because they didn’t have to.

    The Federal Circuit’s decision here affirms summary judgment of obviousness. Viewing all evidence in light most favorable to Odom, they still found that the claims were obvious. Does that not satisfy “clear and convincing”?

    Unless the Supreme Court does the unthinkable and suggests an even more stringent burden of proof for invalidity, Microsoft v. i4i will have no impact on this case. Odom’s claims were already found obvious even under the Federal Circuit’s “clear and convincing” standard, so any adjustment that SCOTUS might make would only further cement the finding in this case.

  107. 52

    Thanks for pointing out the nuance in MS’s position.

    It seems to me that we will never be able to tell what the examiner actually considered, so, in the end, MS’s position must devolve into the position of the PTO in determining the issue of “substantial new question of patentability” during reexamination. If the “issue” was litigated and decided in a prior examination, the Office will not reconsider its decision absent substantial new evidence. This seems right on its face.

    By extension, an enhanced presumption of validity should attach to issues actually addressed in prosecution. The courts and juries should not overturn the considered judgment of the PTO unless they have substantial new evidence.

    So, what do we do about references before the examiner but not discussed? I think they should be given some weight, but obviously, not as much. But they should be in the bin labelled “considered.”

    In my own practice, if I have a reference, of record, that I think more material on the issues under consideration that the reference being used by the examiner, I actually bring it up with the examiner just to avoid what apparently happened to Odom in this case.

  108. 51

    I will look at the case you cited, but I seriously doubt that the fact pattern of that case is going to be close enough to the fact pattern I mentioned above sot that a legal estoppel would be a likely outcome.

  109. 50

    While it is true that legal estoppel is not limited to assignor estoppel, but doctrine is eventually an equitable doctrine. As I see it, legal estoppel doesn’t automatically apply. There has to be an equity-based argument for it to apply. In the above fact pattern, I don’t see the inequity that is going to be caused on O if MS is allowed to argue that claim C is invalid in view of patent P1.

  110. 47

    Really? It is amazing just how MS can take a fact situtation that favors the other side and switch it around to favor their own side.

    Hats off to their litigators.

    Reminds me of the i4i litigation where it seemed to me that they argued enjoining Word would harm the public, thereby putting their monopoly to work for them. The public policy of the US seems to be the opposite, that monopolies are not good in principle, especially if they are obtained or maintained unfairly.

  111. 46

    Parse, I have been around the block, litigating, prosecuting, licensing, both inside and out. I still do all of the above to a greater or lessor degree.

    What do you do?

  112. 45

    Parse, legal estoppel prevents one from taking a contrary position and it is not limited to assignor estoppel.

    Look at the Milgo cases. There the patent owner had won a prior case on a theory that the patented devices had feature X. It turned out that they had marked products that had feature x and some, many actually, that did not.

    The court after reviewing all the facts, concluded that the argument concerning feature X not only was inconsistent with their marking regime, but a lie. The court then held the patents unenforceable for fraud on the court.

    Based on this holding, the losing defendants in the prior case reopened the final judgment and had it reversed.

    Looking back in hindsight, I think the only way Milgo could have “won” is to bring the marking issue up itself and explain why certain products were incorrectly marked. Absent that, they could not take a position in court contrary to the prior position they took in marking.

  113. 44

    Deja Yoda,

    The MPEP provides that you must to submit an IDS that complies with 37 CFR 1.98(a)(1) if you want the references listed on the resulting patent. So its not a full IDS, just a listing of references.

    DC is also correct in that the MPEP specifically states “[t]he examiner of the continuing application will consider information which has been considered by the Office in the parent application.” See MPEP 609.02.

  114. 43

    Ned – One problem with the Microsoft proposal that I discuss above is that no one has been able to articulate a justiciable dividing line between arguments considered by the examiner and those not considered.

  115. 42

    Dennis, now just how can a court handle this? The MPEP commands that the examiner consider the references. This creates a presumption that they have been considered. MS seems to operate on some counter presumption that unless the examiner discusses a reference it has to be presumed that the has not considered the reference.

  116. 41

    Again and again – ask yourself, was the rule followed here?

    Answer again – rule was not.

    And you know that the Examiner didn’t consider the references in the parent because …

  117. 40

    given that the USPTO’s rules require that an Examiner consider such references?

    Again and again – ask yourself, was the rule followed here?

    Answer again – rule was not.

    No presumption earned.

  118. 39

    The issue of consideration and “evidence of consider versus supposed to have consider” is also nonsensical. There is no such thing as supposed to have considered.

    Is there such a thing as a presumption that a reference considered in a parent has been considered in the child application given that the USPTO’s rules require that an Examiner consider such references?

  119. 38

    That estoppel argument (i.e., the defendant is estopped from even arguing invalidity) works if there was an assignor-assignee relationship. That won’t work here.

  120. 37

    DC,

    The MPEP explicitly provides” – only in the case where a proper IDS is filed in the continuation listing the parent – not the case here. See below.

  121. 36

    CAFC could obliquely suggest that Odom had not been forthcoming during prosecution

    There is no such suggestion – oblique or otherwise.

    The issue of consideration and “evidence of consider versus supposed to have consider” is also nonsensical. There is no such thing as supposed to have considered.

    Is. Or is not. That is all.

    Odom – IDS filed in continuation, did not. Blame to Odom, is.

  122. 35

    In an interference proceeding, I think the main issues are: date of conception, date of reduction to practice, and diligence. I believe arguing invalidity in an interference proceeding is akin to shooting yourself in the head.

    What exactly is your line of work Ned? Don’t take this the wrong way. It is obvious that you are very interested in patent law. But every now and then you say stuff that makes me wonder about a few things such as your line of work… so what do you do?

  123. 34

    ” I don’t think the court will want to be in a position where they say a claim is both obvious and non-obvious.”

    But that is the beauty of estoppel. The court never has to say the claim is non-obvious because the defendant can’t even raise the issue in his defense. A court could sua sponte raise the issue itself I suppose…

  124. 33

    Isn’t this just a good example of a defensive disclosure? A patent is a better defensive disclosure than an article, because (1) it is quicker and cheaper to prove it up in court (judicial notice applies) and (2) it makes your defendant look he is contributing and advancing the art, rather than just stealing IP.

  125. 32

    I think I now understand fact pattern you are talking about.

    O asserts claim C against MS. MS owns patents P1 and P2. P2 was filed after P1. P1 is being used as a prior art reference to invalidate C. Let’s also assume that an allowed claim A of P2 is very similar to C. O’s argues as follows: because (1) MS implicitly or explicitly took the position that claim A was not obvious over P1, and (2) claim A is very similar to claim C, therefore, now MS is estopped from arguing that C is obvious in view of P1.

    I’m pretty sure the above argument will not work for the following simple reason. Tomorrow if O asserts claim C against another company, say X, then X will be able to argue that C is obvious in view of P1. I don’t think the court will want to be in a position where they say a claim is both obvious and non-obvious.

    Using your own patent as a prior art reference has its drawbacks. For example, if at a later point MS tries to assert claim A, then I think the defendant in that case would obviously have a strong invalidity argument based on MS’s prior statements.

  126. 31

    In-house, you are correct. The MPEP explicitly provides that the Examiner will review citations from the parent case, and there is no need to cite them again unless you want them to show up on the face of the patent. Is the Federal Circuit unfamiliar with this day-to-day facet of patent prosecution?

  127. 30

    This relates to the pending microsoft v. i4i case. Microsoft and many of its supporters in that case have argued that a patent challenger should face a higher burden of proof when asserting “arguments actually considered by the examiner” than when asserting arguments not considered by the examiner.
    Microsoft would argue that the question whether an argument was considered by the examiner is separate and distinct from the question of whether the patentee satisfied the duty of disclosure or whether the examiner was “supposed to” consider certain prior art on obviousness grounds. Rather, in this case, Microsoft would argue that there is no evidence that the Kavalam patent was actually considered by the examiner on obviousness grounds and therefore a challenger should be able to more easily invalidate the patent.

  128. 29

    This alone justifies a reversal it would seem if this issue was material to the decision, and apparently, it was

    Does the decision say that their conclusion hinged on whether the reference had been considered by the Examiner or not?

    Seemed to me the issue was raised only so that the CAFC could obliquely suggest that Odom had not been forthcoming during prosecution.

  129. 27

    in-house, no, you are not missing something here. The DC and the Feds both held that the reference had not been considered when by law it is presumed to have been considered. This alone justifies a reversal it would seem if this issue was material to the decision, and apparently, it was.

  130. 26

    “The Federal Circuit opinion implicitly suggests that this prior art was not considered by the examiner. Those who disagree may want to support the rehearing request.”

    Isn’t there an MPEP section that says the art cited in the parent is assumed to be considered? That only if the applicant wants the art to be listed on the face of the CON does the applicant need to submit it in an IDS. I am missing something?

  131. 25

    Babble Boy, perhaps I recognized the issue here quickly is because I do lititgate and have argued estoppels and their scope quite a bit.

  132. 24

    Parse, my main point on estoppel was not in interpreting the prior art, but in later filing a patent application on the same invention. That filing include an affidavit of a MS inventor stating that he believe that he first invented the disclosed invention. MS would have been required to identify its own Kavalam reference, and include claim that not only were not anticipated by Kavalam, but were, in their view, not obvious over Kavalam.

    They cannot take a contrary position in court.

    Imagine if you were in an interference and the opponent argued that his own claims were non obvious over a reference and your identical claims to the same invention were not.

    I suspect that not only you, but the board would be nonplussed.

  133. 23

    Babble Boy, no doubt the result here was highly related to the disparity in legal resources. If Odom did not raise and argue the right issues, he cannot complain. But I did get a sense from Dennis’s post that he did raise the issues, but somehow still lost where both the law and the facts appeared to be on his side.

  134. 21

    Facts are not Ned’s strong suit. Running around shrieking “The sky is falling!!! The sky is falling!!!” is more his bag.

  135. 20

    Dennis, this is an excellent post of yours on the defensive benefits of filing patent applications. Especially, filing patent applications on the details of planned new products before they are launched or published to create 102(e) and 102(g) benefit dates as of the filing dates.

  136. 19

    Ned: “Without even looking into the facts in detail, there seems here to be a significant miscarriage of justice.”

    This attitude is precisely why you should never represent anyone in litigation. Not even yourself. Not even for a traffic violation.

    Calm down. Take a deep breath. Look at the facts. Do a timeline. Things are never what they seem.

  137. 18

    I know what estoppel is, but I don’t follow your comment. Dennis’s article specifically talked about the interpretation of a prior art reference in the context of obviousness after KSR.

    But, since you brought it up, let’s talk about estoppel. How does estoppel affect the interpretation of a prior art reference? Note that we are talking about things that are outside the four corners of the patent. To the best of my knowledge, I have never seen the actions of an applicant of a prior art reference affect the interpretation of the prior art reference. Wasn’t that Dennis’s point?

    All I’m asking for is one case. Even if it is from a hopelessly confused district court judge. Just one case.

  138. 17

    Based on his email he sent me the other day he is not kicking himself at all. He’s as hard headed as they come. Although iirc he tried to get an attorney but the court only gave him 2 mo after his other one left.

  139. 15

    First, if I recall correctly, estoppel requires not only that the estopped party asserted an inconsistent argument in a related case, but that they actually prevailed with that argument. Did the second MS application issue as a patent?

    Second, MS would not have needed to argue non-obviousness over Kavalem in the second application. Based on 103(c)(1), the Kavalem patent would not have been prior art for obviousness purposes against the second MS application, but would have been against Odom.

  140. 12

    Parse, I think the issue is estoppel, not obviuosness. I agree with you that MS’s filings on Odom’s invention are irrelevant to the issue of obviousness, but they are directly relevant to the issue of estoppel.

  141. 11

    Dennis, I think the issue of estoppel is here. Fraud would arise if Odom asked MS for MS own patents and applications on the Odom invention and whether MS intentionally concealed the very one that was the smoking gun.

    MS own filings are not otherwise relevant to the issue of obviousness. But they are directly relevant to the issue of estoppel.

  142. 10

    Aqua, thanks. I assumed Dennis had it right.

    About the “seemingly” contradictory filings, perhaps there is a reason we have double patenting, mandatory cross referencing of related patents, etc.

    The only real question is whether the invention indentified and described in the “later” MS patent was the same or substantially the same as that of Odom’s. If so, at a minimum, MS should be estopped as a company to come into court and declare that Odom’s patent on the same invention is obvious.

    The fraud issue will involve whether MS was ever asked whether it sought to patent the same or substantially the same invention as patented by Odom, and how it answered that question.

    Now, if the court suggested that such post grant filings are not relevant to the issue of obviousness, I would agree. But that hardly the issue here is it?

  143. 9

    Agent Gillette,

    Your blade is dull. If you read the material, you would notice that Kavalam is not the referenced patent application that is the point of Ned Heller’s post. There is no question that Kavalam was a prior art reference. There is a second reference that is post Odom’s application that purports (per Mr. Odom – take that for what it’s worth) to be the same invention as Mr. Odom’s.

    In other words, and per Mr. Odom, Microsoft itself realized that Kavalam could not cover Mr. Odom’s invention because Microsoft filed a second patent application after BOTH Kavalam and Odom.

    The question to be answered is why would Microsoft swear that they were the rightful inventors of features supposedly invented after BOTH Kavalam and Odom, and then be able to ignore their own submission to the Office.

    But brace yourself for an easy answer: Microsoft has legions of attorneys and near countless applications, and even though they are one company, their filings often overlap and contradict. I am quite certain that this is not the only instance of seemingly contradictory filings.

  144. 8

    The 102(e) point is interesting for me. Holding a claim bad for obviousness on the basis of some document that, at the date of the claim, was a secret shared by just MS and the PTO strikes me as a rum do for all who were not the first to file something speculative at the PTO.

    I know: that is the law, in the USA, and one must accept it. But all the same, I can’t help wondering what sort of train wreck is coming, when 102(e) docs are available for obviousness attacks under First Inventor to File. I have in mind that the heaviest criticism of ROW First to File is that the “Race to the Patent Office” forces inventors to file prematurely, while their conceptions are still only speculations.

    For completeness, I should add that premature filing is the worst option in Europe. A non-enabling disclosure will itself fail, and will not stop the later filer of an enabling disclosure but it will foul your own later-filed applications. We call it “self-collision”. In Europe, 102(e) art is not available for obviousness attacks. I think Odom in Europe would have, more or less without dispute, got a full measure of protection.

    Is that one more reason why Big Corp do not want the EPC in the USA? I mean, Big Corp thinks it will always file ahead of the little guy, and so wants a much more aggressive “Winner Take All” law than EPC First to File is capable of delivering.

  145. 7

    Ladies and gentlemen, the winner of The Most Civil Comment of the Year goes to …

  146. 6

    Do I understand this correctly, Microsoft itself filed a patent application on the very same invention that Odom patented, indicating at the time it filed that Microsoft not only thought that (Odom’s) invention was patentable over a prior Microsoft patent to Kavalam, but swore to it in writing and under oath, but was still allowed in litigation against Odom to assert the contrary?

    No, you do not. Kavalam is the Microsoft patent.

  147. 5

    To clarify my second point. My understanding of KSR is that the “flexible” approach to obviousness relates to broadening the scope of the combined teachings of multiple references.

    As far as I know, there is nothing in KSR that allows you to limit the scope of a prior art reference. If that is what you meant, I think you are dead wrong (with all due respect, of course).

  148. 3

    Agree completely Ned.

    If the courts wanted to rule against Mr. Odom because they didn’t like him personally and/or his approach to trying to win a case; which is frankly not even close; they should have just said so.

    Miscarriage of justice doesn’t even begin to address what’s been done to Mr. Odom.

  149. 2

    In addition, the patent rules force a more complete disclosure and therefore may result in better documentation of the invention and a broader scope of disclosure than what would have been otherwise published.

    The patent rules do not force a more complete disclosure and often do do not result in a better documentation of the invention. In the EE/CS arts, a research paper (in the case of univ.) or a whitepaper (in the case of a company) typically documents the invention much better than a corresponding patent which usually only provides as much details as necessary to support the claims.

    However, I agree that a patent is a better prior art reference because the patent is broader and shallower, and both of those qualities make it a better prior art reference. And that is a direct result of the patent law.

    Here, that guidance seems to mean that a court should consider extrinsic facts that tend to expand or limit the interpretation of the prior art reference.

    Can you provide a specific example? Extrinsic actions by Microsoft should not have any bearing on the interpretation of the prior art. What is the legal basis for this?

    A prior art reference is to be interpreted from the view of a PHOSITA. I don’t see how Microsoft’s actions can have any effect on that interpretation. Actually, I don’t even think it is practical to use the prosecution history of a prior art reference to limit the scope of the prior art reference. Has anyone used that strategy successfully?

  150. 1

    Do I understand this correctly, Microsoft itself filed a patent application on the very same invention that Odom patented, indicating at the time it filed that Microsoft not only thought that (Odom’s) invention was patentable over a prior Microsoft patent to Kavalam, but swore to it in writing and under oath, but was still allowed in litigation against Odom to assert the contrary?

    Not only do I think that Microsoft has a lot a gaul, but I think there is something very very wrong in this case from an ethics point of view. What Microsoft is done here smacks of inequitable conduct and fraud on the court.

    And do I further understand correctly that even though the patent rules require the examiner to consider the art considered in the parent, the listing of that art on the face of the patent being a mere formality, that both the District Court and the circuit court held, contrary to the patent office rules that require the examiner to consider that art, that the art was not so considered?

    Freaking travesty!

    Without even looking into the facts in detail, there seems here to be a significant miscarriage of justice.
