Percentage of Patents that were Initially Rejected

Academic Studies, Articles and Publications, Patent, Patent Prosecution

This relates to my statements regarding the percentage of applications that receive at least an initial rejection. The graph below shows the percentage of patents issued (2000-2006) that were initially rejected by the PTO broken up into groups of art-units. Thus AU 1630 group actually includes AU 1630 – 1639. Close to 95% of the patents issued through the AU 1630 group during that period were initially rejected before being eventually allowed.

As with the design patent discussion yesterday, the rejection rate above is for applications that eventually issue as patents. For any given application, the effective rejection rate was likely higher because abandoned applications are probably more likely to have been rejected.

This data is now getting a bit old – but it is what it is. This data came from public PAIR before researchers were blocked from accessing it in any substantial way. Since 2006, applicants have complained of increased rejections. My perception that this change is not a shift toward more first office action rejections, but rather a shift toward sustaining more of those rejections in the second and subsequent office actions.

Design Patents: Sailing Through the PTO

Academic Studies, Articles and Publications, Design Patent, Patent, Patent Prosecution

Over eighty percent of utility patent applications are initially rejected during prosecution. Some areas of technology – such as semiconductors – have a lower rejection rate while others – such as electronic commerce methods – have an even higher rejection rate.

I wanted to compare the result for utility patents with design patents. I pulled up information on 1000 of the most recently issued design patents (all issued in March, 2009) and parsed through the file histories to see how design patent prosecution compares. As the graph below shows, in my sample, only 25.6% of the recently issued patents received an initial rejection during prosecution. To be clear, this 25% rejection rate is for applications that eventually issue as patents. To get an overall picture of design patent rejections, we need to also consider the applications that are abandoned and never issue as patents. Recent PTO statistics show that a bit under 20% of design patent applications are abandoned. Because design patent file histories are kept secret unless a patent issues, we cannot know why any individual case is abandoned – However, the two most likely situations are that the applicant (a) failed to respond to a rejection or (b) failed to pay the issue fee. Even if we assume that 100% of the abandoned cases are initially rejected, that only pushes the initial rejection rate to about 40%.

As the graph below shows, of the 1000 issued design patents in my sample, only 4.1% received a final rejection during prosecution; and only 0.2% cases (2 out of 1000) included a notice of appeal. None of the 1000 cases included an appeal brief.

The design patents in the study had an average pendency of 15.3 months calculated by finding the number of months between the filing date and the issue date. As may be expected, applications that included at least one rejection took considerably longer to issue (21.5 months) as compared to those that were never rejected (13.2 months). (These means are different at 99.9 CI).

Most design patents (58%) in my sample have only one inventor. However, 69% of the inventors are listed as joint inventors. A number of the muliti-inventor patents included trans-national inventorship with inventors originating from two or more separate countries. About 1% of the applications listed at least one inventor from the US & Great Britain. Another 1% listed at least one inventor from both the US and China.

Best Practices for Trade Secret Protection

Articles and Publications, Patent, Trade Secret

I recently attended a conference of senior corporate patent counsel. Much of the discussion focused on cost savings in a tight economy. In patent prosecution, this process has been going on for years by limiting prosecution fees and filing abroad only on important cases. Part of the discussion focused on short-term mechanisms to push off cost – such as using provisional and timing PCT applications.

New Focus on Trade Secrets: One alternative suggested is increased reliance on trade secret. Trade secrets are relatively much cheaper than patents. Trade secret protection is automatic so long as sufficient steps are taken to keep the secret and the secret is economically valuable. Patent filings are dropping and many companies are taking a harder look at trade secret law as a mechanism to at least temporarily protect rights.

The public benefit of public disclosure is often touted when comparing patents with trade secrets. Patents require public disclosure with the aim of promoting the flow of ideas and information. Trade secret laws prohibit disclosure.

The private benefit of private disclosure: Anyone who has practiced trade secret law intuitively knows that patents naturally create additional information benefits that I call “private disclosure.” I note two of these benefits below: The benefit of defining rights

Value of Defining Rights: Despite serious problems with claim scope unpredictability, patents do a good job of explicitly stating the rights being claimed. Defined rights can be sold, traded, and accounted-for both externally and within the company. And, patent law facilitates a process for looking at by-product innovations to consider whether they should be pursued. These benefits flow from Coase’s work on property rights. Although trade secrets can also be well defined, trade secret law does not require explicit pre-identification nor does it provide such a mechanism. Rather, in most cases, a company’s knowledge about its own trade secret information is left nebulous and largely undefined.

Employee Relations: The patent system also creates a nice mechanism for managing employee relations. Inventors typically have a duty to assign all their work-related inventions to their employer. However, that duty is crystalized when the inventor files an oath and an assignment of rights. Often, the inventor gets a cash bonus at that point as well. Although the inventor already had a duty to assign, the actual assignment is important psychologically – to ensure that all the parties agree who owns what. Typical trade secret practice does not involve any explicit acknowledgment of the trade secret nature of particular innovations and information. Some companies attempt an end-of-employment statement that This is important because most trade-secret practice involves former employees using inside knowledge to benefit a competitor.

Best Practices for Trade Secret Law: Most companies have invention disclosure programs, but few of them link those disclosures to trade secret practice. Notably, when a company decides not to pursue patent protection, a process of assignment (and possible small bonus) should still be followed to ensure that the creator understands that the innovation belongs to the company and is not being given to the public. Likewise, companies may consider implementing broader innovation identification programs that encompass both patentable inventions and trade secret information.

Notes:

  • One query: In the US, trade secret law is state specific – although most jurisdictions follow the Uniform Trade Secret Act. Do any jurisdictions have a “working” requirement for trade secret? Take the situation where a company employee creates a new product, but the company decides not to pursue the product and it just sits in the file cabinet?
  • China: In the US, the commercialization of trade secrets will block the user from later obtaining a patent on the otherwise secret information. A Foley & Lardner report by Sharon Barner and Hal Wegner indicates that under Chinese law, there commercialized trade secrets may still be patented. Is this true in other FTF countries?

Inequitable Conduct: Trends at the Federal Circuit

Academic Studies, Articles and Publications, Inequitable Conduct, Patent,

In Larson Mfg, Judge Linn revived the call to rebuild the ramparts protecting patent applicants against charges of inequitable conduct. For some sense of history, I used Westlaw to pull-up the past twenty-five years of Federal Circuit decisions and counted the number of decisions that at least mention “inequitable conduct.” The result is a clear increase in the number of decisions discussing inequitable conduct. Although the absolute number of Federal Circuit patent decisions has also risen somewhat, the growth rate of IC decisions greater.

The graph below shows the number of Federal Circuit decisions that at least mention “inequitable conduct” for each year 1984-2008.

200903191000.jpg

2009 may buck the trend. As of March 19, 2009, only two decisions mentioned inequitable conduct (Larson Mfg., and Rothman). At that rate, we might project only nine or ten decisions for the entire year.

I use the ‘mention’ of inequitable conduct here because the stated ‘plague’ primarily focuses on the allegations of inequitable conduct. The mere allegations of inequitable conduct are certainly harmful to the patentee. However – more than that – they are harmful to the profession and to the patent system as a whole by continually suggesting that patent attorneys and patent agents are facilitating fraudulent activities.

Rooklidge: Patent Reform Damages Provision Violates Seventh Amendment

Academic Studies, Articles and Publications, Damages, Patent, Patent Legislation, , ,

The following post is by Bill Rooklidge. Rooklidge is a patent litigator and former head of the AIPLA. He clerked at the Federal Circuit in the early 1980’s.

Richard Cauley’s March 14, 2009 guest post accurately characterized the damages reform provision of the Patent Reform Act of 2009 as “a judicial nightmare” because of its procedural complications, attendant delay and reversal potential. Two additional problems with that provision merit note: it perpetuates prior art subtraction and introduces into jury trial multiple potential violations of the Seventh Amendment.

Fact-finding and the Seventh Amendment. The Supreme Court coined the term “gatekeeper” in Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993), to describe the trial court’s obligation to “ensure that any and all scientific testimony or evidence admitted is not only relevant, but reliable.” In addition to rulings on Daubert motions, courts also fulfill their gatekeeper role by ruling on motions for summary judgment and judgment as a matter of law, motions in limine, evidentiary objections, and jury instructions. The bills’ damages section would enhance the courts’ gatekeeper role, but in doing so unconstitutionally invade the jury’s province as fact finder.

The bills would add to 35 U.S.C. §284 paragraph (c)(1), which would require the court to select from three methods for calculating a reasonable royalty “based on the facts of the case and after adducing any further evidence the court deems necessary.” A procedural rule requiring the court to weigh evidence to select from alternate theories would be void for depriving the patentee of its right to jury trial. See Fidelity & Deposit Co. of Maryland v. United States, 187 U.S. 315, 320 (1902). A genuine issue of material fact, that is, a dispute over facts that might affect the outcome, requires the issue to go to the jury. See generally Anderson v. Liberty Lobby, 477 U.S. 242 (1986). Similarly, the trial court’s exclusion of the entire market value rule under paragraph (c)(1)(A) for the patentee’s failure to make “a showing to the satisfaction of the court,” would violate the Seventh Amendment in a jury trial in which the patentee presents enough evidence to create a genuine issue of material fact. See Minks v. Polaris Indus., Inc., 546 F.3d 1364, 1372 (Fed. Cir. 2008) (vacating because trial “court necessarily engaged in an independent review of the evidence and substituted its conclusion for that of the jury on the factual issue of compensatory damages”).

The first section of the bills’ section (c)(1)(B) authorizes trial courts to exclude the patentee’s prior licenses for failure to make a “showing to the satisfaction of the court” of three facts regarding the claimant’s other licenses:

“the claimed invention has been the subject of a nonexclusive license for the use made by the invention by the infringer”;

the licenses have been extended “to a number of persons sufficient to indicate a generally marketplace recognition of the reasonableness of the licensing terms”; and

“the license was secured prior to the filing of the case before the court.”

The court also must determine whether the infringer’s use is “of substantially the same scope, volume, and benefit of the rights granted under such license. The second sentence of paragraph (c)(1)(B) requires a similar procedure for noninfringing substitutes for the infringing product or process. And paragraph (c)(1)(C) likewise requires the court to “conduct an analysis to ensure that a reasonable royalty is applied only the portion of the economic value of the infringing product or process properly attributable to the claimed invention’s specific contribution over the prior art.” A court making these findings would invade the province of the jury where the patentee presents substantial evidence on these issues.

Prior Art Subtraction. Section (c)(1)(A)’s requirement for application of the entire market value rule that the “claimed invention’s specific contribution over the prior art” be the “predominant basis for market demand” is just the latest form of “prior art subtraction.” Use of “specific contribution over the prior art” is an attempt to separate the “gist” or “heart” of the invention from the patent claims, and would introduce the extra step of subjectively redefining the scope of a patent. The Federal Circuit long ago rejected using the “gist” or “heart” of the invention to determine obviousness, see Para-Ordnance Mfg. v. SGS Importers Int’l, Inc., 73 F.3d 1085 (Fed. Cir. 1995), and recently rejected using the “point of novelty” in design patent law. Egyptian Goddess, Inc. v. Swisa, Inc., 543 F.3d 665, 678 (Fed. Cir. 2008). Stripping the prior art elements out of the claimed invention that has been examined by the USPTO, construed by the federal district court, and relied upon to determine validity and infringement, in no way approximates the “heart” or “gist” of the invention, and that inherently subjective process would be unfair to the patent owner, and would eliminate application of the entire market value to inventions consisting entirely of prior art elements, arguably the vast majority.

Paragraph (c)(1)(C) would limit the reasonable royalty base to the “economic value of the infringing product or process properly attributable to the claimed invention’s specific contribution over the prior art,” replacing apportionment with prior art subtraction. This analysis is no substitute for the sophisticated and nuanced apportionment approach available under existing case law such as Georgia-Pacific Corp. v. United States Plywood Corp., 318 F. Supp. 1116, 1133-37 (S.D.N.Y. 1970). Paragraph (c)(1)(C) would address the combination invention problem by stating that for combination inventions “the contribution over the prior art may include the value of the additional function resulting from the combination, as well as the enhanced value, if any, of some or all of the prior art elements as part of the combination, if the patentee demonstrates that value.” This analysis, which finds no precedent in existing case law and lacks any readily definable economic standards, does not even begin to address the problem that subtracting the prior art elements simply does not approximate what the inventor really invented.

Replacement of “contribution over the prior art” with the “essential features” language from the Supreme Court’s recent Quanta Computer, Inc. v. LG Electronics, Inc., 128 S. Ct. 2109 (2008), would just put another label on prior art subtraction. Regardless of label, the bills’ damages provision would drastically reduce patent owners’ ability to obtain reasonable royalty damages, which could not be less fair to those, like independent inventors, research institutions and universities, that have no ability to obtain lost profits damages.

Notes

Guest Post: Hot Topics in US Patent Reexamination

Academic Studies, Articles and Publications, Guest Post, Patent, Reexamination, , ,

By Robert Greene Sterne. Rob Sterne is a founding director of the IP firm Sterne Kessler Goldstein & Fox. I asked him to write about current ‘hot topics’ in patent reexamination.

pic-11.jpg

The marked increase in the use of reexamination has naturally caused more frequent and closer evaluation and scrutiny of its unique procedures by involved parties and the courts. In FY2008, according to official USPTO (PTO) statistics, 168 inter partes reexams and 680 ex parte reexams were instituted. Compare this to FY2005, where 59 inter partes reexams and 524 ex parte reexams were instituted just three years ago. In short, it is becoming one of the faster developing areas of intellectual property law and, in the words of top PTO officials, it is a true “work in progress.”

Developed in conjunction with the Sedona Patent Litigation Conference and a team of my colleagues (and incorporating feedback of dozens of sources including judges, senior officials from the PTO, patent litigators, patent prosecutors, academics, bloggers, and interested members of the public), a comprehensive and neutral white paper overview of this subject matter provides an in-depth review of hot issues currently confronting parties that find themselves in the “parallel universe” of patent reexamination and concurrent litigation in the district courts and USITC. The hot topics addressed include (A) impact of PTO decisions on stock price, (B) reexamination pendency, (C) substantial new questions of patentability, (D) real party in interest, (E) duty of disclosure, (F) protective orders, (G) stay of litigation in view of reexamination, (H) appeals from the Central Reexamination Unit to the Board of Patent Appeals and Interferences, (I) the impact of reexamination on settlement, and (J) page and time limits in reexamination proceedings.

Here is a closer look at three of these topics:

  • Litigation Stays: Reality or Myth – The percentage of reexams that are in the ‘parallel universe’ of district court or USITC patent litigation continues to climb. For example, in FY2008, 62% of current inter partes reexams and 30% of ex parte reexams were in parallel litigation. Judges have wide latitude in granting or denying stays and litigants must carefully evaluate prior stay decisions from their judge and the court they are in to effectively prognosticate how the judge will rule. Especially with respect to inter partes reexams, the grant of a stay can effectively be “game over” for the patent owner.
  • Stock Fluctuation: Impact of PTO and Court Decisions on Stock Price – The practical impact of reexam on patent owners can be enormous. There are recent celebrated examples of stocks dropping 40% in hours after the release of a non-final office action rejecting claims in a suit, even though this development is not controlling on a court case because the reexam is not final. Third party requestors engage in litigation in the press by issuing inflammatory press releases that spin the truth. Patent owners need to be prepared for this media battle to protect their stock price. Moreover, the PTO mails decisions to parties in the reexam, putting the patent owner at a real disadvantage in dealing with the potential reexam media war.
  • Reexamination Pendency: So How Long Does it Take? – The stated goal of the PTO CRU is 24 months from the time the reexam is instituted to a Final CRU office action or action closing prosecution. By statute, the CRU must handle reexams with “special dispatch.” However, there are no definitive statistics on how long it takes for a reexam to be handled to completion by the CRU and then through appeal at the BPAI. Our current best estimate is that it takes approximately two to four years for the CRU to complete a reexam, typically a little faster for ex parte reexams, and two to four years for the BPAI to complete a reexam appeal. Thus, the reexam process could take four to eight years before it arrives at the US Court of Appeals for the Federal Circuit on appeal. This is a significant amount of time and requires additional strategy and tactical decisions by the parties.

Forward Looking Patent Damages

Articles and Publications, Damages, Injunctions, Patent,

In the wake of eBay, courts and scholars have been working to figure out what to do after denying injunctive relief. A common suggestion is to award an ongoing royalty – often termed a compulsory license. In an impressive body of research stretching back to the year 1660, Lewis & Clark professor Tomás Gómez-Arostegui concludes that “federal courts lack the authority, in either law or equity, to award prospective compensation to plaintiffs for post-judgment copyright or patent infringements.”

Until such time as Congress creates a new form of compulsory licensing, future-damage awards and continuing royalties can only be granted in lieu of a final injunction by consent of the parties.

In non-patent cases, such as accidental death, courts regularly calculate future damages – such as earning capacity. However, in those cases, the award is based on a past tort. In patent cases, prospective damages are based upon future infringing actions.

Looking historically, Gómez-Arostegui could not find a single instance prior to 1789 where the Chancery “awarded a continuing royalty in lieu of a final injunction in infringement cases.” In cases where no injunction was granted, the court did “nothing at all” about ongoing infringement.

How does this cut:

Stays Pending Inter Partes Reexamination

Articles and Publications, Patent, Reexamination

In an earlier post I indicated my suprise that courts continue to “grant stays of litigation pending re-examination – especially inter partes reexaminations which tend to be incredibly slow.” In thumbing through Matthew Smith’s new book on Inter Partes Reexaminations, the following statements caught my attention and reaffirmed my conclusion that stays do not make sense here:

“A fully contested proceeding, therefore, could consume six to seven years. . . . [However t]here is as yet no reliable data available to estimate the total time of the proceeding. As of the end of 2008, the only cases with issued reexamination certificates were those in which technical mistakes were made, or in which at least one party chose not to contest the proceedings.”

The first request for inter partes reexamination was made in 2001 and still no contested inter partes reexamination has completed its course. Mr. Smith’s suggestion of “six to seven years” may well be optimistic.

Part of the Patent Reform Act of 2009 would be to take inter partes reexaminations out of the hands of the examination corps and put it under the direction of “an administrative patent judge.” Under the proposal, the PTO is given authority to spell out the actual procedures. Of course, the Board of administrative patent judges has been handling this sort of trial-in-the-first-instance for many years in the form of interference proceedings. The board already has a trial division that is ready to go. Although there are some outliers, interference proceedings are generally terminted within less than two years. For the Oct-Dec 2009 period, 13 interference proceedings were terminated with an average pendency of 9.5 months. 100% of those cases were terminated in less than two years. See 37 C.F.R 41.200(c) (“Patent interferences shall be administered such that pendency before the Board is normally no more than two years.”)

Notes:

What is a troll patent and why are they bad?

Academic Studies, Articles and Publications, Patent,

By TJ Chiang (Professor at George Mason Law School). Professor Chiang wrote the following squib after reading yet another article complaining about patent trolls.

There is much debate and controversy over the term "patent troll." Let me suggest a fairly narrow definition, but one that identifies a category of patents with distinct problems. Moreover, let me suggest that we should talk about individual patents as "troll patents," rather than entire entities as patent trolls. A troll patent is one that:

  1. Is owned by someone that does not practice the invention.
  2. Is infringed by, and asserted against, non-copiers exclusively or almost exclusively. By copying I mean any kind of derivation, not just slavish replication.
  3. Has no licensees practicing the particular patented invention except for defendants in (2) who took licenses as settlement.
  4. Is asserted against a large industry that is, based on (2), composed of non-copiers.

The problem with a patent troll—or, more accurately, the particular troll patent—that fits all four conditions above is that the troll patent does only two things. First, it gathers dust in the patent office. Second, it inflates prices on products. The patent itself contributes nothing useful to society, in so far as the people who actually make anything useful would have done it equally in the absence of the patent.

These four conditions also rule out a few non-practicing entities; or, rather, many of the patents held by these entities. University-held patents are largely not troll patents, in so far as they are often on substantial advances where the infringers copy. Individual inventors are also not always trolls. An individual inventor that licenses others to commercialize the invention is not a troll; nor where the inventor actually has something significant that gets pirated. But a patent owner who sits in wait to ambush an industry later, with a patent that does nothing otherwise except gather dust, is a troll.

One hypothetical that will surely be thrown at me is the individual inventor who tries to commercialize the invention, but fails, and then sues the industry years later. This inventor is a visionary ahead of his time who was merely unlucky. On the other hand, this inventor still contributed nothing useful to society. It is worth emphasizing the fact that, by my hypothetical, the industry produced the same technology independently, without copying anything from the patent. In the absence of copying by someone else or the commercialization of the product through the patent, I do not see the inventor as having done society much of a favor.

Guest Post: Monsanto Company’s View on Patent Reform – Protect Innovation:

Articles and Publications, Guest Post, Patent, Patent Legislation, , ,

PatentLawPic699 David Snively is Monsanto's General Counsel. He read Google's calls for patent reform and penned the following response. Monsanto's business model relies heavily on its ability to protect its innovations through intellectual property and contract in the US and Globally. Monsanto has also been the defendant in numerous patent battles.

Dr. Alan Greenpan's keynote speech on "Markets and the Judiciary" noted that "critical to economic growth is a rule of law, particularly protection of the rights of individuals and property". His remark that for IP law, the constancy of the protection afforded under the Constitution of the United States and our fully-functioning legal system is the basis for the U.S. economy's sustaining lead – even in difficult economic times with broken markets. Our patent system is the envy of the globe and while capable of thoughtful adjustment should not be hijacked by international pirates or corporations seeking to dilute legitimate protection that breeds investment and jobs. This is why Monsanto Company, as a global leader for innovation and technology in agriculture, is joined by trade unions and countless other groups who strive to assure Greenspan's voice is not lost in the din from hedge funds, offshore interests or others seeking short term gain by weakening our great patent system.

I respectfully disagree with the recent blog post by Google's Head of Patents and General Counsel, commenting on the perceived risks from damage awards in patent cases. Monsanto has faced billion dollar damage claims as a wrongly sued patent defendant and also knows the true benefits from avoiding the encouragement of willful infringement based on a smaller party's calculated gain in the face of limited risk of a meaningful award of damages if infringement is established. With full knowledge of all these issues and our substantial alignment with Google and the information technology industry over the legitimate need to curtail patent trolls and a myriad of other concerns – we encourage thoughtful reform. Last year Congress passed without public objection Public Law 110-403 the "Prioritizing Resources and Organization for Intellectual Property Act of 2008" which was designed to significantly enhance government law enforcement resources for combating certain kinds of intellectual property (IP) theft, e.g. criminal counterfeiting and infringement of computer software. The law helps protect investments in the research, development and marketing of certain kinds of innovative American products and services. The information technology industry was rightly bothered that its intellectual property rights were being trampled on by "pirates".

But, according to the financial sector and the information technology industry it seems that too many other people have too many patents that get in the way of too much "innovation" that is being marketed by an industry that doesn't own the rights to the "innovation". Some say that innovation can't stand still while somebody does a patent search to make sure that the "innovation" that is being marketed won't infringe any of those too many patents. So the complaint is "we are getting sued too much by these innovators who are stifling our innovation". Unlike the solution for rampant copyright infringement the perverse solution for rampant patent infringement is to propose "reforms" that would both reduce incentive to invest in research, development and marketing of innovative American products and services and provided impediments for improving patent quality. Dr. Greenspan's Georgetown keynote aptly recalled the copyright situation when he quoted Stephen Breyer from the Harvard Law Review decades prior to becoming a Justice "the case for copyright…rests not upon the proven need, but rather upon the uncertainty as to what would happen if protection were removed. One may suspect the risk of harm is small, but the world without copyright is nonetheless [in the words of Hamlet] 'undiscover'd country' which 'puzzles the will,/And makes us rather bear those ills we have/Than fly to others that we know not of.'

The problems posed by the patent reform bill are many:

  • It would change the calculation of damages that an infringer (pirate) would pay as compensation for trampling on patent rights, encouraging only more callous disregard of patent rights and piracy.
  • It would change the venue provisions in a way that would impose a substantial burden and inconvenience on patent owners by limiting access to the judicial system, encouraging only more callous disregard of patent rights and piracy.
  • "Technical" changes would weaken protection and encourage piracy via removing the estoppels provisions and expanding the prior art basis for engaging in inter partes re-examination, in effect providing a system of post grant review that will serve only to harass patent owners by effectively taking patents out or service for the duration of unlimited re-examinations, encouraging only more callous disregard of patent rights and piracy.

Transparency is critical to society today yet the patent reform bill would not require publication of all patent applications at 18 months reducing the public knowledge of prior art making it harder to avoid investment in patent-free technology and reducing the likelihood that quality patents will issue.

Thoughtful patent reform is needed. There are things to support in the House version of the patent reform bill. For example, the House bill while strangely modifying the damages calculation would authorize a study to see if such a modification is needed. Such studies are available and do not support the anecdotes that say damage awards are out of control.

Patent Reform that discourages investment in research and development and the job growth and economic stimulus that is spawned by thousands of small companies as well as large companies that rely on a robust and strong patent system is bad for America. Monsanto invests over $2M every day in research and is committed publicly to helping double food yield in corn, soy and cotton by 2030 while using 1/3 fewer natural resources and improving the lives of farmers globally. Accomplishing this task of sustainable agriculture requires a patent system and rule of law that Dr. Greenspan says has always been found in the Constitution of the United States.

Patent Reform 2009: Damages

Articles and Publications, Damages, Patent, Patent Legislation, ,

The most contentious portion of the Patent Reform Act of 2009 is the damages provision. The current damages statute gives little guidance to a court. Damages must be “adequate to compensate for the infringement but in no event less than a reasonable royalty for the use made of the invention by the infringer.” 35 U.S.C. §284. The Court may “increase the damages up to three times the amount found or assessed.” Id. The courts have given some flesh to the rough skeleton created by these statutes. One construct is the hypothetical negotiation – asking the counterfactual question of what licensing scheme would these dueling foes have agreed to if they had actually come to a licensing agreement. The Georgia Pacific factors guide the process of deternining a reasonable royalty. In some cases, courts allow a patentee to recover lost profits.

As it turns out, the damages actually awarded in patent cases are generally thought to be much higher than negotiated license agreements.  Part of the difference stems from the reality that patent damages are awarded only on patents that are known to be valid, infringed, and enforceable, and after the risk and expense of litigation have already been taken. In ordinary license negotiations, these risks lower the potential royalty rate and – in contrast – should increased the level of compensation in post-trial damages.  There is some evidence that juries simply tend toward large damage awards.

Stacking Problem: In some technology areas – such as electronics – this creates a potential problem known as royalty stacking. Most electronics products are covered by multiple patents – often dozens of patents. CDMA2000 communication standard, for instance, reportedly invringes at least 924 patents. [LINK] When each patentee is awarded a 5% royalty, it does not take long before the entire revenue is taken just to pay for intellectual property rights. If everyone has blocking rights then no business can get done, and we see the tragedy of the anti-commons. Of course, stacking is only a problem in theory. CDMA2000 is a standard actually used around the world. Producers are making (some) money. Multiple patents covering products have causes prices to be raised, but it is not clear than any market has been destroyed or even that the royalty payments outway the benefit of the innovation.

Uncertainty Problem: Jury verdicts are quite unpredictable, and because the royalty rules are so loose, damages appeals are rarely successful.

The new legislation appears to take on these problems in a way to (1) reduce the average damage award; (2) make damage awards more rational and predictable; and (3) make damages judgment more subject to appellate review.

The practical approach of the legislation is to create a “standard for calculating reasonable royalty” which require a determination of the “specific contribution over the prior art” to determine damages. Some courts already follow the rules set out in the proposed legislation. Thus, legislation advocates may refer to the damages reforms as simply a clarification that limits the actions of rogue courts.

The proposed text reads as follows:

35 USC 284(c)(1) IN GENERAL.-The court shall determine, based on the facts of the case and after adducing any further evidence the court deems necessary, which of the following methods shall be used by the court or the jury in calculating a reasonable royalty pursuant to subsection (a). The court shall also identify the factors that are relevant to the determination of a reasonable royalty, and the court or jury, as the case may be, shall consider only those factors in making such determination.

”(A) ENTIRE MARKET VALUE.-Upon a showing to the satisfaction of the court that the claimed invention’s specific contribution over the prior art is the predominant basis for market demand for an infringing product or process, damages may be based upon the entire market value of that infringing product or process.

”(B) ESTABLISHED ROYALTY BASED ON MARKETPLACE LICENSING.-Upon a showing to the satisfaction of the court that the claimed invention has been the subject of a nonexclusive license for the use made of the invention by the infringer, to a number of persons sufficient to indicate a general marketplace recognition of the reasonableness of the licensing terms, if the license was secured prior to the filing of the case before the court, and the court determines that the infringer’s use is of substantially the same scope, volume, and benefit of the rights granted under such license, damages may be determined on the basis of the terms of such license. Upon a showing to the satisfaction of the court that the claimed invention has sufficiently similar noninfringing substitutes in the relevant market, which have themselves been the subject of such nonexclusive licenses, and the court de termines that the infringer’s use is of substan tially the same scope, volume, and benefit of the rights granted under such licenses, damages may be determined on the basis of the terms of such licenses. ”

(C) VALUATION CALCULATION.-Upon a determination by the court that the showings required under subparagraphs (A) and (B) have not been made, the court shall conduct an analysis to ensure that a reasonable royalty is applied only to the portion of the economic value of the infringing product or process properly at tributable to the claimed invention’s specific contribution over the prior art. In the case of a combination invention whose elements are present individually in the prior art, the contribution over the prior art may include the value of the additional function resulting from the combination, as well as the enhanced value, if any, of some or all of the prior art elements as part of the combination, if the patentee demonstrates that value.

”(2) ADDITIONAL FACTORS.-Where the court determines it to be appropriate in determining a reasonable royalty under paragraph (1), the court may also consider, or direct the jury to consider, any other relevant factors under applicable law.

USPTO Maintenance Fees

Academic Studies, Articles and Publications, Revival, USPTO News

A large portion of PTO revenue comes through applicant’s payment of maintenance fees. Under the current fee structure, three post-grant maintenance fees must be paid in order to keep a patent from prematurely expiring. A large entity pays $980 3.5 years after issuance; $2,480 7.5 years after issuance; and $4,110 11.5 after issuance. If the fee is not paid then the patent will expire at the next 4, 8, or 12 year mark. In FY08, the PTO reported over $500 million in revenue from maintenance fees.

I wanted to look at how maintenance fees are being paid, so I downloaded the past decade of OG Notices and parsed-out notices of patent expiration. The chart below shows some results.

PatentLawPic686

The chart shows survival rates for the four (red), eight (blue), and twelve (green) year marks. Each datapoint represents the average survival rate for patents that would have expired on that date. For instance, of the 2229 utility patents that issued on December 31, 1996, the first fee was paid for 84% of the patents, the first two fees were paid for 63% of the patents, and all three fees were paied for 49% of the patents. (Note – I did not yet add-back cases that were revived due to unintentional abandonment.)

The median patent has an ordinary enforceable term of about 17 years. This is based on the twenty year term which begins at filing of the non-provisional application minus three years of prosecution. If prosecution takes longer than three years, then the term will likely be extended under the PTA provisions.

However, this data shows that the median patent term is actually cut short by about five years because applicants decide not to pay the large final fee.

A third feature to recognize from this chart is that the percentage of patents whose fees are being paid is increasing over time. However, the PTO has indicated that it expects a drop in maintenance fee payments due to the economic slump.

Judge Moore looked at expiration data for patents issued in 1991 in her paper on “Worthless Patents.” Her result is that patents were more likely to “survive” (i.e., have their maintenance fees paid) when they have more claims, more art cited, more related applications, and longer prosecution times. US corporate owners were more likely to pay the fees than individual or foreign owners. She also found that Semiconductor and Optics patents were the most likely to survive. Amusement patents were unlikely to survive.

Provisional Patent Applications: Waiting to File Non-Provisionals

Academic Studies, Articles and Publications, Patent, Provisional Patent Application

For better or worse, provisional patent applications have always been used as a way to delay patent prosecution. The procedure has become popular as a relatively cheap and informal mechanism for preserving priority of invention without losing patent term. Although a provisional application sets a priority date, the application does not even reach the examination queue until the full utility patent application is filed. Thus, on average, each day of delay in filing the utility patent application pushes the issue date back one day as well. However, provisional applications also serve as a mechanism for extending the tail end of the patent term because the twenty-year patent term does not begin to run until filing of the utility patent.

Provisional applications have become quite popular. In FY2007, for instance, over 132,000 provisional applications were filed and about 30% of recent patents assigned to US companies reference a provisional filing. [Link]

To see how provisional filings are being used, I compiled a set of 65,000 patents that issued sometime between Jan 2007 and Feb 2009 (inclusive). All the patents in the group share the common property of claiming priority only to one or more provisional applications. I additionally excluded patents that made other priority claims such as continuations, divisionals, and continuations-in-part. Once I formed the set of patents, I then looked at the filing date of the provisional application compared with the filing of the utility application to how applicants are using the extra year of deferred examination. For patents claiming priority to multiple provisional applications, I used the date of the earliest filed provisional application.

The graph below shows the result. The vast majority of applicants wait until the year is almost up before taking action and filing the non-provisional application. About two-thirds of the non-provisional applications were filed with less than ten days remaining in the one-year provisional pendency. In over ten percent of the cases, applicants properly filed the non-provisional more than 365 days after the original provisional filing because of weekends, holidays, and/or leap year.

Two weeks ago, I had a conversation with a patent litigator about the propensity of patent attorneys to barely meet deadlines. He was worried about the potential for malpractice claims against his firm. And, here, I found a surprising number of cases that appear to miss the deadline.

My lingering question for patent attorneys and applicants — why delay so long? Is it simply a matter of doing work according to deadline? Does it matter that delaying filing the application also delays the eventual issuance of the patent?

References Cited

Academic Studies, Articles and Publications, Patent, Patent Prosecution

I compiled a list of the over five hundred thousand reference citations in the almost eighteen thousand utility patents issued in the past two months. (Jan 1, 2009 – Feb 18, 2009, excluding reissues and reexaminations). In this sample, the average patent issued with 31 cited references. This is a skewed average – the median patent only cites 15 references. The vast majority of references (77%) are introduced by the applicant during prosecution while less than a quarter (23%) are cited by the examiner.

Patent documents (including US & foreign issued patents and published applications) represent 82% of the cited documents while non-patent literature represents 18% of the total. As was noted in the comments regarding PTO search tools, PTO searches are overwhelmingly focused on patent documents. Thus, 95% of references cited by PTO examiners are patent documents. (See pie chart aside).

Although – on average – applicants submit most of the prior art, Applicants submitted absolutely no references (zero) 15% of the patents in my study, and the median number of references cited by the applicant is only 7. Applicants cite over 200 references in only 2% of cases. The PTO’s stalled IDS rules give the applicant 20 ‘free’ references that can be cited without payment of a fee or further description. About 23% of the issued patents in my sample include more than 20 references cited by the applicant. The chart below is a histogram of applicant submitted references. About 12% of patents are “off the chart.” In those cases the applicant cited more than 40 references.

Take-away: First, the data shows that applicant submitted references are substantially different from those cited by examiners. Non-patent literature is an important category of prior art that is largely missed by examiners, and the current information disclosure system does a pretty good job of getting more of that type of art in front of the examiner than he or she would otherwise see. A second point is that most of the time, examiners are not being swamped by reference submissions. It is surprising that 15% of patented cases include absolutely no applicant cited references. On the other hand, folks who submit over 200 references are deliberately choosing to do so. Generally, the very large reference volume comes in cases where the applicant knows that the innovation is important and is looking for more assured protection. In those cases, I don’t see the harm in making the applicant somehow pay for the additional resources required to review those references. [Of course, in that case, the PTO should allow more examination time as well]

The next graph shows the average number of applicant-cited references for various top-patenting companies. The size of the blue bar reflects the number of applicant cited reference on average, for that assignee’s Jan-Feb 2009 patents. (Scale at bottom). The graph is sorted so that companies with the greatest average number of cites are shown at the top. Although this is not strictly true, the difference between companies is largely a difference in areas of technology. Thus, companies patenting electronics generally cite less prior art than others. You may also notice in this list that US based companies tend to cite more prior art. The final chart in the series shows that – on average, US assignees submit over three times as many prior art references as do their foreign counterparts or patents without an assignee.

Extending Patent Terms

Academic Studies, Articles and Publications, Patent

ScreenShot016I looked again at patent term adjustments (PTA) for US patents. 3294 utility patents were granted on February 17, 2009. Of those, 2467 (75%) included some patent term adjustment based on PTO delays in prosecution under 35 U.S.C. § 154(b). For each of these patents, some additional quantum of exclusivity is added to the end of the patent term so long as maintenance fees are paid.

The median adjustment was just over one year (376 days) with the average adjustment of 430 days. The longest adjustment in the group was over five years (1958 days). That patent (No. 7,490,438) is directed to an automobile door and is based on an application filed in 2000. In that case, the applicant appealed twice. The examiner was reversed both times. The applicant lost 11 potential PTA days for filing an IDS after the first office action.

Notes

Percent of Patents Discussing “Microsoft,” part II

Academic Studies, Articles and Publications, Patent, Patent Prosecution, Software

In an earlier post, I introduced some data relating to patents that discuss Microsoft somewhere in the patent document. That post showed that almost 5% of newly issued patents refer to the software giant in some way. That data also showed a strong upward trend over time. The post received a few interesting comments as well as a few suggestions. [LINK] In response, I have added some additional data to the graphs. The first graph below shows the percent of patents that discuss Microsoft (in blue) and now also includes the percent of patents that are assigned to Microsoft (in red). Several years ago, Microsoft publicized their intention to obtain a large number of patents. That intention is becoming a reality, and Microsoft recently obtained its 10,000th patent. However, only about 20% of patents that discuss Microsoft are actually assigned to the company.

The next graph compares the patents discussing “Microsoft” with other products/companies. Here, I include patents that discuss “Microsoft” (blue), “UNIX” (green), “LINUX” (red), and “Apple” (tan). UNIX has seen some growth, but not much since the mid 1990’s. In the past couple of years, the number of LINUX patents have grown dramatically, but still pale in comparison to Microsoft patents. Although the absolute numbers for LINUX related patents are still small, they are surprisingly high based on the anti-patent lore of LINUX developers. Apple has remained steady over the years. Of course, my results for Apple should be tempered by the false positive results that actually refer to the fruit rather than the computer company or its products.

An issue in all these graphs is time lag. The time lag of issued patents may be easily seen by searching for patents that discuss “Google.” – The result is only 1342 patents but 4682 published applications.

Percent of Patents Discussing “Microsoft”

Academic Studies, Articles and Publications, Patent, Software

I looked at all patents that include the word “Microsoft” somewhere within the patent document. These include patents assigned to the company as well as well as patents that simply refer to Microsoft in the specification or list of cited references. That almost 5% of new all patents refer to the software giant is a sign that the company’s technology serves as a creative platform for ongoing developments.
