Cornell wins $184 Million in Damages for Past Infringement by HP

Damages, District Court, Inventors, Patent, Patent Cases 2008, ,

Federal Circuit Judge Randall Rader has been sitting by designation as a district court judge in the Northern District of New York.  His case is an epic patent battle between Cornell University and Hewlett-Packard (HP), and the jury trial recently concluded with an $184 million calculated as 0.8% of HP’s $23 Billion in sales.

The patent — No. 4,807,115 — issued in 1989 and expired during the seven years of litigation. It is directed toward an internal computer messaging mechanism that boosts the function of multi-processor computers.

Interestingly, Cornell and HP had discussed a licensing agreement as early as 1988 (even before the patent issued). In 1997, Intel licensed the ‘115 patent for use in its Pentium Pro chips.

Unpublished Thesis: In a pre-trial decision, Judge Rader denied Cornell’s motion in limine and allowed HP to show the jury an unpublished masters degree thesis as 102(b) prior art.  The court found the thesis publicly accessible because the thesis had been cited in a later article that was in the same area of technology as the issued patent (analogous art.).

“After weighing all the circumstances of accessibility, this court views as vitally important the citation of this scholarly work in the Tjaden-Flynn article.”

Inventor Rewards: Unlike most companies, universities generally offer a percentage royalty cut for its employee-inventors. Professor Torng, the inventor of the ‘115 patent, will reportedly receive 25% of the award (if it is ever paid). Torng has announced that he’ll only keep a few million and donate the rest (perhaps over $30 million) to charity.

The post-trial decisions and eventual appeal should be interesting.

  • Sitting by Designation: The CAFC has continued to offer district court judges from across the country the opportunity to sit on the appellate bench for a day. On June 3, 2008, Judge Ward from the Eastern District of Texas filled out a panel with Judges Newman and Gajarsa. They will be deciding three patent cases: Hyatt v. Dudas (waiver of arguments before the BPAI); Atlanta Pharma v. Teva (appeal from denial of preliminary injunction to stop teva from selling a generic version of the ulcer med Protonix); and D Beam v. Roller Derby.
  • New USPTO Fees: They are going up, but you can put in your two cents by July 3. [New Fees][Contact Walter.Schlueter@uspto.gov. Include RIN number RIN 0651–AC21 in the subject line.]
  • FTC Commissioner Rosch recently spoke about patents and antitrust. He believes that the FTC Act, the Clayton Act and the Sherman Act all create “viable enforcement tools” against companies that create “patent walls” — especially when they acquire those patents from third parties. The FTC is currently going after N-Data in a case where the patent covers an ethernet standard. [N-Data][Zura’s Comments] Three important cases on this issue:
    • US v. Singer Mfg (Antitrust violation to charge competitors with patent infringement after U.S. company obtained patent from Swiss company)
    • Kobe v. Dempsey Pump (obtaining and using “every important patent” in the field in order to exclude competition, together with other anticompetitive activity, constitutes an antitrust violation)
    • Case of Xerox Corp (settlement consent decree where FTC challenged Xerox’s purchase of additional plain paper copier patents).
  • Pre-Purchase Review: There is some room to debate here on the question of organic-patenting (patents on inventions via the company’s own R&D) versus acquisitional-patenting (buying up patents invented by others). At the firm level, acquisitional growth is typically reviewed much more harshly for potential antitrust violations than is organic growth. Is the FTC/DOJ headed toward a system of pre-purchase review of major patent acquisitions in the same way that the agencies conduct pre-merger reviews?

A First Look at Who Files Provisional Patent Applications

Academic Studies, Accelerated Examination, Articles and Publications, Patent, Provisional Patent Application, Transnational,

Patent.Law083As part of the 1995 patent law overhaul, the USPTO began allowing patent applicants to file provisional patent applications.  Over a decade later, these lower-cost provisional filings have taken hold.  According to PTO annual reports, over 132,000 provisional patent applications were filed in fiscal year 2007. In perspective, that number is over 30% of the number of the 439,000 non-provisional utility patents filed during the same period. This proportion has been slowly rising since 2002 when the provisional applications filing rate was about 27% of the non-provisional rate.[1] That year (2002), the PTO recorded just under 90,000 provisional applications and 332,000 non-provisional patent applications.

Interestingly, in my study of recently issued patents, only 21% reference a provisional application as a parent. (In the study, I look at approximately 15,000 utility patents issued in April and May 2008.) [2] 

Patent.Law085National Tool: Over half of the recently issued patents that listed an assignee indicated that the assignee was a foreign (non-U.S.) corporation or agency.[4]  Although foreign entities are not prohibited from filing provisional applications, the provisional tool was designed to benefit U.S. entities. Thus, it is not a surprise that only 5% of the patents assigned to international applicants were associated with a provisional application while 30% of the patents assigned to a U.S. applicant were associated with a provisional application.  Two countries – Israel and Canada – stood out as filing the highest proportion of provisional parent claims. Both of these countries are known for having patent attorneys with a high level of familiarity with U.S. laws.  Only 2% of the Japanese & Korean patents included provisional parent claims. [Updated June 03 with Corrected Figure]

The provisional application provides a potential extra year of patent eligibility at the end of the term.  Thus, it is also not surprising that new drug inventions – where a potential year at the end of the term is most valuable – have the highest rate of association with a provisional application.[5]  Likewise, patents on electrical and electronic applications had the lowest rate of provisional filing even after excluding the international applications.

The provisional filings appeared to have almost no impact on the pendency time of a patent application as measured by the number of days from filing the nonprovisional to issuance.  This makes sense as no examination takes place until the nonprovisional application is filed.

The following table also provides some interesting comparisons of patent strategy.[6]

USPTO Examiner Guidance on Business “Processes”

Patent, Patentable Subject Matter

Patent Attorney Jeff Spangler recently attended the PTO’s business method partnership where he received a copy of the written clarification given to examiners to help them determine when a claimed business method is eligible for patent protection as a statutory process under 35 USC 101.  According to the memo:

“Based on Supreme Court precedent and recent Federal Circuit decisions, the Offic’s guidance to examiners is that a Section 101 process must (1) be tied to another statutory class (such as a particular apparatus) or (2) transform underlying subject matter (such as an article or material) to adifferent thing. If neither of these requirements is met by the claim, the method is not a patent eligible process under Section 101 and should be rejected as being directed to non-statutory subject matter.

An example of a method claim that would not qualify as a statutory process would be a claim that recited purely mental steps. Thus, to qualify as a Section 101 statutory process, the claim should positively recite the other statutory class (the thing or product) to which it is tied, for example, by identifying the apparatus that accomplishes the method steps, or positively recite the subject matter being transformed, for example by identifying the material that is being changed to a different state.

The Multi-Factor Test for Declaratory Judgment Jurisdiction in Patent Cases

Declaratory Judgment, Patent, Patent Cases 2008

PatentLawPic324Cat Tech LLC v. TubeMaster, Inc. (Fed. Cir. 2008)

Cat sued TubeMaster — alleging infringement of its patent covering a method of using a catalyst loading devices to simultaneously load thousands of tube reactors.  Cat’s infringement allegations were focused on one particular TubeMaster commercial configuration. During the litigation, TubeMaster filed a counterclaim for declaratory relief that its other three configurations did not infringe. On appeal, the CAFC first looked to see whether the district court had proper jurisdiction over the declaratory relief counterclaims.

In MedImmune, the Supreme Court rejected the Federal Circuit’s “rigid” two prong test for DJ jurisdiction that required that the DJ plaintiff (1) have a reasonable apprehension that the patentee will file suit and (2) conduct “meaningful preparation” to conduct potentially infringing activity.  The MedImmune decision eliminated the first prong — finding the that the “reasonable apprehension” test excluded at least some actual “cases and controversies” under Article III of the U.S. Constitution. 

New Multi-Factor Test for Declaratory Judgment Jurisdiction: In Cat Tech, the Federal Circuit found that the second prong of “meaningful preparation” is still intact — at least as a factor working to determine whether a dispute is immedate and real.

“[T]he issue of whether there has been meaningful preparation to conduct potentially infringing activity remains an important element in the totality of circumstances which must be considered in determining whether a declaratory judgment is appropriate. . . . If a declaratory judgment plaintiff has not taken significant, concrete steps to conduct infringing activity, the dispute is neither ‘immediate’ nor ‘real’ and the requirements for justiciability have not been met.”

From this decision by Judge Mayer, it appears that the new test for DJ jurisdiction has moved from two prongs to a broader “totality of the circumstances” under the umbrella of a “fundamental inquiry” of “whether the facts alleged, under all the circumstances, show that there is a substantial controversy, between parties having adverse legal interests, of sufficient immediacy and reality to warrant the issuance of a declaratory judgment.”  (quoting MedImmune). Meaningful preparation toward potential infringing activity is important (but perhaps not a required element) in this fundamental inquiry because actual steps taken toward infringement are indicators of both “immediacy and reality.”

On the facts of this case, the CAFC found “meaningful preparation” toward each product was sufficiently shown by “AutoCAD drawings for each of its four configurations”; successful manufacture of one of the configurations; being ready to deliver products under any configuration “within a normal delivery schedule” after receiving an order; and because the company “does not expect to make substantial modifications to its loading device designs once production begins.”

Finally, although also a factor in the analysis, the fact that TubeMaster had not created any sales literature or begun advertising its alternate configurations did not negate the immediacy and reality of the controversy.

Affirmed.

Federal Circuit Contract Interpretation

License, Patent, Patent Cases 2008, ,

PatentLawPic308Lawler Mfg. v. Bradley Corp. (Fed. Cir. 2008)(nonprecedential)

In 2001, Lawler and Bradley settled a patent infringement lawsuit and entered into a contractual license agreement. Bradley was given the right to practice Lawler’s plumbing valve patents in exchange for a 10% royalty.  The license included a combination royalty provision. The royalty licensed parts sold in combination would be charged at a separate (likely lower) royalty rate. 

The dispute on appeal was whether a set of example combinations included in the contract limited the “combination” royalty rate to only a limited set. The particular contract provision read as follows:

“If a Licensed Unit is invoiced or shipped in combination in another product such as an emergency shower or eyewash, [then the combination rate applies.]”

De Novo Construction: Looking much like a claim construction opinion, the CAFC reviewed the contract language de novo (following Indiana law) and reversed the lower court interpretation. In particular, the court found that the “such as” language of the contract limited the combination royalty to only a limited set of combinations. The CAFC found its interpretation necessary to give meaning to the such as clause. As with Federal Circuit claim construction law, Indiana contract law has a preference for giving meaning and effect to all written terms.

“The question before us is whether that term, read in the context of the agreement, is restrictive, as Lawler urges, or merely explanatory, as the court found. We find that it is restrictive. “Such as” refers to items similar to what are recited rather than indicating that the recited items are just examples of what is covered by that provision. . . . The parties’ inclusion of the “such as” phrase … must either have been intended to provide some guidance as to the limited types of combinations that the parties contemplated … or to provide meaningless surplusage. Indiana law constrains us from finding the latter.”

Reversed and remanded.

In dissent, Judge Mayer saw the “such as” language as merely providing examples in much the same way that embodiments provide example implementations of an invention. “[E]mergency eyewashes and showers are examples of combination products, but they are not the only combination products covered by section 3.1 of the licensing agreement.”

First Sale Doctrine: Copyright & Patent

District Court, First Sale / Exhaustion, Patent, Patent Cases 2008, ,

PatentLawPic307In some ways, the Supreme Court case of Quanta v. LGE is a symbol of the ongoing struggle between property law and contract law.  With concepts like the first sale doctrine (and the rule against perpetuities), property law has typically operated to limit dead hand and downstream control over property rights.  These limiting doctrines are largely ignored in a freedom of contract regime.

Vernor v. Autodesk (W.D. WA 2008)

A federal copyright case last week landed on the side of property & the first sale doctrine.  The court denied summary judgment to Autodesk — finding instead that Vernor may well have a legitimate right to re-sell his copies of AutoCAD. Autodesk argues that he only holds a contractual license to use the software (via shrink-wrap license) and does not actually hold full property interests in the programs.

“[T]he transfer of AutoCAD packages from Autodesk to CTA was a sale with contractual restrictions on use and transfer of the software. Mr. Vernor may thus invoke the first sale doctrine, and his resale of the AutoCAD packages is not a copyright violation.”

In copyright law, the first sale doctrine is codified in statute — allowing the owner of a particular copy to resell that copy even if the owner had contractually agreed not to do so. 

“[T]he owner of a particular copy or phonorecord lawfully made under this title … is entitled, without the authority of the copyright owner, to sell or otherwise dispose of the possession of that copy or phonorecord.” 17 USC 109.

In patent law, the first sale doctrine – also known as patent exhaustion – has no statutory support. Rather, like the doctrine of equivalents, patent exhaustion is grounded in common law principles.  The Quanta case is fairly technical and could result in a narrow low-impact opinion. However, it is also quite possible that the Supreme Court will re-solidify the property concepts.  Expect a decision within the next few weeks.

Notes:

  • Patry and InternetCases have more details on the Autodesk case.
  • More on Quanta v. LGE.
  • Comment on Chain of Title: M. Slonecker: “For the sake of factual accuracy, AutoDesk “sold” the software to CTA. At a later date CTA auctioned off its assets, and Mr. Vernor was the winning bidder for the software program discs. With copies in hand, Mr. Vernor placed the discs he purchased at the auction on sale at eBay. Apparently AutoDesk is not pleased with this state of affairs and has been engaged in a running battle with Mr. Vernor about his eBay activities.”

… and See What Sticks: Claim Construction Appeals

Claim Construction, Patent, Patent Cases 2008,

Rattler Tools v. Bilco Tools (Fed. Cir. 2008) (nonprecedential)

Rattler sued Bilco in the Eastern District of Louisiana — alleging that Bilco’s magnetic scrapper (used to clean out oil wells) infringed several patents. After a bench trial, the district court found the patents completely non-infringed. In particular,the district court held that the “accused products and methods did not meet any of the thirteen limitations ofthe ten asserted claims.”

Rattler appealed — asking for a new claim construction for each of those thirteen limitations.  Without any detail analysis, the CAFC politely showed Rattler the door.  “We have considered all of Rattler’s arguments. Having done so, we see no reason to disturb the careful and thorough post-trial decision of the district court.”

This case is unremarkable in its short analysis, but does serve as a reminder of the current state of patent appeals.  The conventional wisdom that the CAFC re-writes a large percentage of claim construction decisions leads most losing parties to appeal on claim construction.  At the same time, appellants are also including more claim construction arguments in each appeal. 

CAFC: Failing to Submit Invention Inspiration OK; Failing to Submit Product Code of Preferred Input Not OK.

Best Mode, CAFC, Patent, Patent Cases 2008, , , ,

PatentLawPic305TALtech v. Esquel Apparel (Fed. Cir. 2008) (nonprecedential)


Summary: (1) An applicant need not disclose its own prior work or inspiration for invention if merely cumulative of other references cited; (2) Failing to identify the brand of adhesive tape used in the invention was a best mode violation — resulting in claim invalidation; (3) There is no presumptive order of the steps in a process claim – unless the claim language “requires an ordering of steps” either implicitly or explicitly.

One of TAL’s employees – John Wong – was inspired by TAL’s use of heat-fusible adhesive tape in manufacture raincoats. Over a long process of trial and error, Wong figured out how to use a particular variety of adhesive tape to create a dress shirt that does not pucker after washing. 

After receiving a US utility patent, TAL became embroiled an patent litigation with another Hong-Kong based manufacturer – Esquel Apparel. In that litigation, the district court found TAL’s patent unenforceable due to inequitable conduct during prosecution and invalid for failing to submit fulfill the “best mode” requirement of 35 U.S.C. 112 (inter alia).  Based on the inequitable conduct, the court also awarded attorney fees to Esquel.

Inequitable Conduct: “In this case, the district court found TAL liable for inequitable conduct because inventor John Wong had not disclosed the raincoat seam that inspired his invention to the PTO.” On appeal, the CAFC first dispelled any notion that a patent applicant is required to disclose the inspiration for the invention. Although not stated by the court, 35 U.S.C. 103(a) arguably indicates that the inspiration is not relevant to the patentability inquiry: “Patentability shall not be negatived by the manner in which the invention was made.”

Here, the CAFC noted that TAL’s raincoat may well have been “merely cumulative” to a German patent application that was submitted during prosecution. “If the undisclosed raincoat seam was merely cumulative to [the German application], then no inequitable conduct lies in its nondisclosure.”

Best Mode: At the time of filing, Wong had settled upon a particular type of adhesive tape – known as Vilene SL33 – as the best way to form the seams.  The patent application did not, however, disclose Vilene SL33.  A patent may be invalidated for failing to submit a “best mode” if (1) the inventor possessed a best mode at the time of filing; and (2) the written description fails to disclose the best mode in a way to allow one reasonably skilled in the art to practice that mode.


Possession of the Best Mode: The evidence clearly showed that Wong “experimented with many adhesives but settled on a preference for one.” Thus, the court agreed that the first prong was met — the inventor did possess a best mode at the time of filing – i.e., Vilene SL33.

On the second prong the CAFC disregarded the applicant’s argument that the PTO “prefers the use of generic names of products” and that there is no evidence that the Vilene brand products are actually better quality than other brands.  Instead, the court honed-in on the result of the first prong – that Vilene SL33 was the best mode known to the inventor – and agreed that the best mode had not been disclosed. “TAL has not explained how the written description teaches one having reasonable skill in the art the way to practice the best mode as found in the analysis of the first prong – the use of Vilene SL33.”

Process Order: “Generally, there is no presumption of order, and so a claim with many steps can be infringed by an accused process performing the claimed steps in any order. However, we will find that the claim requires an ordering of steps when the claim language, as a matter of logic or grammar, requires that the steps be performed in the order written, or the specification directly or implicitly requires such a narrow construction.”

In this case, the claimed process implicitly requires a particular ordering. In particular, the bonding adhesive must be presented before a folding step because the folding step requires that the garment abut the bonding element.

Conclusion: The asserted claims were found invalid and not infringed. The remand appears only necessary to determine inequitable conduct and consequently potential attorney fees.

USPTOExaminers.com

Patent,

According to the website, USPTO Examiners (www.usptoexaminers.com) “is a website designed for professionals to anonymously review, rank, and learn about a patent examiner or a trademark examining attorney who works at the United States Patent and Trademark Office (USPTO).” Law Firms are also reviewed.  The site’s motto is “We Examine the Examiners.”

The owners of the site are anonymous. In addition, the comments are anonymous, but pointed. As an example, the following comment was recently published about a particular examiner (named on the site):  

“The work I have reviewed from him plainly indicates his incompetence. I have had to appeal every case where he was the examiner. And I got him reversed at the Board every time. I think he falls into some kind of job protected category. That is the only reason I can think of why he has not been fired.”

You can also find positive comments about particular examiners, such as the following:

“I have called Primary Examiner Truong several times regarding my searches. Primary Examiner Truong is helpful and knowledgeable about the topic and the classification system. If you are trying to do a search, I recommend calling Primary Examiner Truong. If Primary Examiner Truong is not available I recommend calling Primary Examiner Mendoza in the same Group Art Unit.”

Although the owners of the site have not revealed their names, I sat down the other day and had a virtual conversation with UE.

Patently-O: I understand that you want to remain anonymous. However, can you give readers some clue as to who you are? [a patent attorney; group of attorneys; law students; patent examiners; PTO Director]

UE: I am an intellectual property practitioner. 

Patently-O: Why did you start the USPTO Examiners site and what is its purpose?

UE: I have always believed in providing high quality work to my clients without their incurrence of unnecessary costs.  When I first started practicing intellectual property law, in my personal opinion, patent examiners and the patent practitioners (e.g., patent attorneys and patent agents) were working towards accomplishing the goal of promoting technological advancement.  To that end, there was a mutual exchange of ideas in a collegial environment.

However, over the past few years, at least in my opinion, it appears as though some of the patent examiners are less interested in learning the patent rules, applying the patent rules appropriately when examining a patent application, and/or the consequence of their decision.  Moreover, some of the patent examiners have developed an “us (examiners) against them (patent practitioners) attitude.”

As a result of some of the patent examiners’ actions and mentality, the cost of prosecuting a patent application has increased.  One option to potentially prevent making costly arguments that fall on deaf ears would be to know what successful strategies other patent practitioners used when working with a particular patent examiner.  Another option would include increased training for examiners so that the patent practitioners do not spend their clients’ money teaching the patent examiners the law and the application of the law to the specific facts of a case.  As such, I created a vehicle in which patent and trademark practitioners can post information about their individual experiences, as well as their opinions (their concerns and their satisfaction) about patent examiners and trademark examining attorneys with whom they have worked.

I believe that the experiences and the opinions of patent and trademark practitioners can potentially serve four purposes.  First, if an individual who reads the information posted on my website is a patent or trademark practitioner, that individual may factor in the posted experiences and opinions of other patent and trademark practitioners when determining the competency and responsiveness of a particular patent examiner or trademark examining attorney to better serve their clients.  Second, if an individual who reads the information posted on my website is in charge of training patent examiners or trademark examining attorneys, that individual may decide that it is necessary to investigate whether an examiner or a trademark examining attorney needs additional training in particular areas.  Third, the positive comments will encourage and praise the competent patent examiners and trademark examining attorneys to continue doing the great job that they have been doing.  Finally, the non-positive comments will hopefully encourage the affected patent examiners and trademark examining attorneys to improve their work product or their mentality.

It is likely that some of the patent examiners in the same technology Group Art Unit and some of the trademark examining attorneys in the same Law Office discuss the strengths and weaknesses of a particular patent or trademark practitioner to better strategize their Office Action.  I am not doing anything different with this website.  I have simply created a forum that allows patent and trademark practitioners to anonymously discuss their opinions about a particular patent examiner or trademark examining attorney to better strategize their responses to Office Actions.  For example, one post mentioned that the patent practitioner had an appointment to meet with an examiner.  However, the examiner was not in his office at the designated time and even after arriving at his office a couple of hours later, he still ignored the patent practitioner who was waiting at the security desk.  When a patent practitioner reads a comment like the one above, he or she can better determine whether meeting this particular examiner for an interview would or would not be a good use of the clients’ money. 

It is important for everyone to realize that there is no way to check the accuracy of an anonymous posted comment.  Therefore, each posted comment should be taken for what it is, and the individuals who read the website should not base their entire strategy on a posted comment.

Patently-O: Do you expect that these reviews will improve the examination process?

UE: I believe that patent examiners and trademark examining attorneys have a difficult and stressful job.  I hope that my website will make a small contribution in improving the examination process by improving the work product and knowledge of the examiners as discussed above.  Furthermore, I hope the patent and trademark practitioners can use the information to save time and their clients’ money. 

Patently-O: Why are you remaining anonymous? Do you expect that you’ll be ‘outed’ at some point?

UE: As some of the comments made on some of the IP blogs indicate, this website appears to be somewhat controversial.  I have gone out of my way to program the website so that the identity of the individuals who post their opinions remain anonymous.  This is to ensure that those individuals may post their opinions without the fear of reprisal from a patent examiner or a trademark examining attorney.  For the same reason, I would like to remain anonymous.

With respect to being outed, it is likely that I will be outed at some point.  I hope that by that time, this website is well respected, is seen as a source for improving the patent process system, and is used as a factor to better strategize prosecuting a patent or trademark application. 

Patently-O: Users have already posed what appear to be defamatory comments on the site. Are you planning to monitor the site and take any action to stop such activity?

UE: I do not continuously monitor the messages.  However, I do review my e-mail at contact@usptoexaminers.com once a day.  As stated on the top portion of the message board, “USPTO Examiners’ message board is provided simply as an informational resource. Information is provided as is; no guarantees, warranties or representations are made as to its accuracy or completeness. The posted messages are simply opinions of the message drafters and do not represent opinions of USPTO Examiners, its affiliates, officers, directors, employees, consultants, contractors, and agents.

If you find an offensive, defamatory, or inappropriate message or comment, please report it to us at contact@usptoexaminers.com.”  Furthermore, the legal notice provides the terms and conditions for using the website.  Most of the users of this website are professionals who, I would hope, would use their common sense as to what is or what is not an appropriate comment. 

Patently-O: Any suggestion on folks I could talk with about the site who would go on record?

UE: Not at this time.

Patently-O: Gracias

Theory of Dependent Claims: Survey Results

Academic Studies, Articles and Publications, Claim Drafting Tips, Patent, , , , ,

Patent claims define the scope of an invention much like metes and bounds define real property boundaries or a statute delineates the difference between criminal and non-criminal activity.  Often, patent applicants submit a series of claims all directed toward the same invention. Various independent claims allow an applicant to focus on various aspects of the invention. These broad aspects may be directed to various nodes of a larger system or regions of a compound, processes for creating or using various elements, etc.  Dependent claims by definition add additional limitations. Thus, for instance disputed claim 1 and 2 from the recent Lovanex dispute reads as follows:

1. A heterogeneous intimate admixture of sulfated heparinic polysaccharides … consisting essentially of

from 9% to 20% of polysaccharide chains having a molecular weight less than 2,000 daltons
from 5% to 20% of polysaccharide chains having a molecular weight greater than 8,000 daltons, and
from 60-86% of polysaccharide chains having a molecular weight of between 2,000 and 8,000 daltons ….

2. The heterogeneous polysaccharide admixture as defined by claim 1, comprising less than 2% of dermatan sulfate.

Claim 2 is interpreted to include all the limitations of claim 1 with the additional limitation of “less than 2% of dermatan sulfate.” See 37 CFR 1.71(c).

Earlier this week, I polled Patently-O readers on why they file dependent claims and received just over 1000 responses. (Listed below).

Responses were also allowed to add additional reasons in the comment section. I have compiled a few of those individual responses below.

  • Drafting Process: A few responses commented on the iterative process of drafting a patent. For some, drafting the dependent claims helps refocus and redefine potentially problematic terms from the independent claims. For many, the dependent claims also serve as a guide for fully drafting the specification.
  • Prosecution Process: Some responses proposed that the dependent claims are helpful during prosecution for several reasons. First, there is a perception amongst patent practitioners that examiners read and consider the claim-set before looking at the actual specification. For that reason, the claims should be considered as a way to teach the examiner about the features and purpose of the invention.  For some, obvious limitations in a dependent claim are useful in that regard to show the examiner an intended use (practical embodiment) of the invention.  For those who see patent prosecution as a negotiation, a series of narrowing dependent claims speed up the the process — the applicant and examiner need only agree upon how narrow the claims need be.  Some propose at least some dependent claims being “super narrow” to serve as a “foot in the door” to increase the likelihood that there is at least some patentable subject matter.  Once you have agreed that a patent will issue, it may be easier to debate the scope of the eventual claims. On a practical note, the existence of dependent claims means that an applicant can get to a post-final rejection allowance without filing a request for continued examination. These practical concerns are important considering that the vast majority of patent applicants amend their claims during prosecution.
  • Claim Differentiation: Most practitioners agreed that the claim differentiation benefit of dependent claims is important. The doctrine encourages courts to consider that each claimed element covers something different than the others. Pushing that line, a typical reasoning is that two or more dependent claims providing alternative implementations of a term from an independent claim will help ensure that the independent claim element is not limited to a single embodiment. Some folks quibbled with my statements regarding dependent claims “expanding scope” of other claims and instead used a more PC version of “aiding construction.”  It is important to realize that the originally filed dependent claims also form part of the specification and can thus help overcome enablement and written description hurdles.
  • Appeasing Clients: Many inventors see their invention narrowly — as their particular embodiment. Dependent claims provide an easy way to satisfy the inventor’s desire to claim their invention without limiting legal rights. On this “politics” side — dependent claims also give reason to add joint inventors, which may be good for office politics. “An invention may only warrant one independent claim embodiment, but many clients like to see many claims. They believe the more claims they have the stronger the patent and that they are getting value for there money.So you add them, e.g., a blue widget, a red widget. It is like chicken soup for a cold, it can’t hurt.”
  • Ease of Analysis: “Filing dependent claims rather than only independent claims makes it much easier for several parties (attorneys prosecuting the application, examiners and the BPAI examining the patent, attorneys analyzing the issued patent, courts analyzing the issued patent) to more readily evaluate the differences and similarities of claims.”  Others noted that it is also useful as a way for potential licensees to know that the proposed product is literally and explicitly covered. For some patent owners, this “ease of analysis” is actually a negative. (Try to read NTP’s $600,000,000 claims). A long claim-set makes it more likely that a potential defendant will easily cave rather than pursue an expensive invalidity / noninfringement study.
  • Capture “minor inventions”: Dependent claims allow an applicant “to capture improvements to the invention that are not important enough to justify a separate application, but that one would want to avoid having a competitor step in and patent something similar.”
  • Tradition: There is nothing wrong with tradition and custom. It helps ensure that we’re all on the same page.  For many the 3/17 rule of independent/dependent claims serves as a default rule that can be adapted for unique circumstances.
  • International: Internationally, patents use fewer independent claims than in the US. One European attorney made the following comment: “Multiple independent claims in the US style cause major headaches and costs in Europe, so one good independent, with well gradated dependents, is the best solution for me.”

New Counsel On Appeal Does Not Overcome Waiver of Novelty Argument

Patent, ,

PatentLawPic303Golden Bridge Tech. v. Nokia and Lucent Tech. (Fed. Cir. 2008)

Golden Bridge’s patent covers a CDMA mobile communication scheme that gradually ramps-up the communication power signal in order to avoid interference with other mobile phones.  On summary Judgment, the E.D.Texas court held that Golden Bridge’s patent CDMA mobile communication scheme asserted claims were anticipated by the prior art.

Anticipation is a question of fact normally decided by a jury. However, it may be amenable to summary judgment “if the record reveals no genuine dispute of material fact.”

Waiver of Novelty Argument: On appeal, Golden Bridge argued that the prior art does not disclose a claimed synchronization element. That factual contention, however, was only first presented on appeal. Finding that Golden Bridge had ample opportunity to raise the contention at the district court level, the CAFC found that any appeal on the synchronization issue had been waived.

“There is no reason why Golden Bridge could not have raised the issue of whether the synchronization limitation was disclosed in the Häkkinen [prior art] reference during the summary judgment proceedings either before the magistrate judge or before the district court judge. . . Golden Bridge cannot simply choose to make its arguments in iterative fashion, raising a new one on appeal after losing on its other at the district court. This is an appellate court and as such we abide by the general rule that new arguments will not be decided in the first instance on appeal.

New Counsel: Golden Bridge argued that it should be given another opportunity to raise the issue because it had hired new counsel on appeal. The appellate panel quickly rejected that argument — holding that “[n]ew appellate counsel does not present an exceptional case or circumstance in which our declining review will result in injustice. To hold otherwise would open the door to every litigant who is unsuccessful at the district court to simply hire new counsel and then argue he should get to raise new issues on appeal.”

Not Fact Finders: Although not directed at any particular colleagues, Judge Moore’s opinion here strongly re-states the the limited role of the Federal Circuit as an appellate panel: “Appellate courts review district court judgments; we do not find facts. Middleton v. Dep’t of Def., 185 F.3d 1374, 1383 (Fed. Cir. 1999) (‘[A]s an appellate court, we may not find facts . . . .’).”

Notes:

  • Based on a request by Nokia, the patent is concurrently under reexamination at the USPTO.

Anti-TrafFix: Design Patent Provides Evidence of Non-Functionality in Trade Dress Claim

Design Patent, Patent,

PatentLawPic302In TrafFix Devices v. Mktg. Displays, the Supreme Court held that the existence of an expired utility patent covering a particular product design provides strong evidence that the design is “functional.”* Consequently, a party would be had-pressed to claim non-functional trade dress protection for the previously patented design. In Keystone Mfg. v. Jaccard Corp., the W.D.N.Y. federal court explored how trade dress protection is impacted by an expired design patent.

Expired Design Patent: Jaccard’s hand held meat tenderizer is covered by its U.S. Design Patent No. D 276,685. The design patent expired in 1998 – seemingly leaving an open avenue for direct copycat competition.  As part of a larger lawsuit, however, Jaccard asserted trade dress rights over its product.

Functionality: Jaccard argues that design patents should be treated as the mirror image of utility patents in a functionality analysis: If a utility patent creates strong proof of functionality, a design patent should provide presumptive evidence of non-functionality.

The district court rejected the suggestion that the design patent creates a presumption of non-functionality.  Instead, the court held that the design patent simply serves as another piece of evidence to be used by the jury in determining non-functionality. This conclusion comports with McCarthy on Trademarks:

“A design patent, rather than detracting from a claim of non-functional trade dress or trademark, may support such a claim . . . [W]hile a design patent is some evidence of non-functionality, alone it is not sufficient without other evidence.”

Curiously absent from this decision is any analysis of the populist notion that expiration of a patent transfers to the public a right to copy and use the patented elements.  

  • * Although there are various definitions of functionality, in trade dress law the term generally refers to whether the element is essential for the product’s use or affects the cost/quality of the product. Only non-functional designs are protectable as trade dress.
  • Keystone Mfg. v. Jaccard Corp., 2007 U.S. Dist. LEXIS 13094 (W.D.N.Y. Feb 26, 2007).
  • There are several cases in conflict with Keystone Mfg on this point. Fuji Kogyo Co., Ltd. v. Pac. Bay Int’l, Inc., 461 F.3d 675 (6th Cir. 2006) (noting that a design patent serves as presumptive evidence of non-functionality).

 

Federal Circuit Jurisdiction Extends to Non-Patent Portion of Consolidated Case

Patent

Cytologix Corp. v. Ventana Medical Systems (1st Cir. 2008).

CytoLogic filed two separate lawsuits against Ventana — alleging (1) patent infringement and (2) antitrust violations.  Both cases were managed by the same judge who held two trials. In a post trial order, the court stated that the cases had been informally consolidated and ordered that they be consolidated “nunc pro tunc.” CytoLogix appealed to the First Circuit (and also to the Federal Circuit).

The Court of Appeals for the Federal Circuit has exclusive jurisdiction over all appeals arising under the federal patent laws.  Here, the antitrust action did not arise under the patent laws. However, the First Circuit held that upon consolidation, jurisdiction for the case as a whole was at least partially based on the patent laws — thus providing the Federal Circuit with exclusive jurisdiction over the appeal.

Appeal dismissed.
