Cancelling a Patent Claim

by Dennis Crouch

The pending case of Jump Rope Systems v. Coulter Ventures is fascinating to me as someone who teaches both property and civil procedure. The basic questions: (1) As an inter partes review (IPR) proceeding draws to a close – toward cancellation – at what point are the claims no longer enforceable? (2) What is the effect of cancellation, in particular, is it like canceling a magazine subscription where the former subscriber isn’t off the hook for past-due bills; or, is it like an annulment – an Ab Initio Extinguishment?  The case also (3) raises a straight-up due process challenge to the IPR system.

A typical IPR where the petitioner prevails includes the following three-step sequence:

  1. Unpatentable Decision: PTAB issues a final written decision concluding that the challenged claim has been proven unpatentable with a preponderance of the evidence.
  2. Affirmed on Appeal: On appeal, the Federal Circuit affirms that judgment.
  3. Certificate of Cancellation: Once the appeal is complete, the USPTO Director then issues a certificate canceling the claim. 35 U.S.C. 316.

The first question — if the patentee is involved in concurrent district court infringement litigation, at what step is the patent no longer enforceable?

Clearly, the patent claim is canceled at Step-3 and by that point cannot be enforced going forward. The Federal Circuit though has held that the claim is already unenforceable at Step-2 based upon the court’s questionable application of collateral estoppel.   I call it questionable because of the different standards  of proof applied in the PTAB vs the District Court.  The affirmed PTAB decision found the claim invalid with a preponderance of the evidence.  But, in district court litigation invalidation requires clear and convincing evidence, a substantially higher standard. And, a conclusion of invalidity under a lower standard does not conclusively tell us that the same claim would have been proven invalid under a higher standard.  Using a standard approach such as found in the Restatement (Second) of Judgments, collateral estoppel would not apply here because of the difference in standards.  Here, we tend to use an exacting standard for res judicata principles because of their due process implications — the result bars a party from making their argument in court.  The Federal Circuit’s fudging of the rule makes some practical sense – the statute appears to make the issuance of the cancellation certificate a ministerial process with its “Director shall” language.  And yet, fudging the rules in a way that undermines due process is troubling.  I’ll note here that courts appear to generally be waiting for the appeal decision before announcing preclusion, although it is unclear whether that approach is somehow required or simply prudential (since district courts generally see the Federal Circuit as unpredictable).  I’ll also note that I previously called out the Federal Circuit for improper expansion of preclusion law with regard to the Kessler Doctrine – they did not listen to me there either.

The second question at issue in Jump Rope Systems involves the impact of cancellation — what about infringement that occurred (and lawsuits pending) prior to the cancellation?

The reissue system is a somewhat-close relative to inter partes review and has the benefit of 150 years of case law, including numerous Supreme Court decisions.  With reissues, courts have clearly held that cancellation of claims during reissue render those claims entirely moot.  See, for instance, Moffitt v. Garr, 66 U.S. 273, 283 (1861) and Meyer v. Pritchard, 23 L. Ed. 961 (1877).  But, the reissue system has a significant difference — a reissue begins with a patentee surrendering its patent as required by statute. 35 U.S.C. 251.  It is that surrendering that makes the cancellation of claims in a reissue so dramatic.

With inter partes review, the patentee does not surrender the patent and so we have a potentially different situation.  Still, courts have regularly treated cancellation of claims as voiding the claims backward and forward through time.  But, it is not so clear that approach is correct and there are many situations where the courts have given “cancel” to only prospective effect.  In its briefing, Jump Rope cites a long string of cases in various areas of law as well as simple plain meaning of the word:

Plain English is in accord. “Canceling” a magazine subscription stops future deliveries, but past issues remain in hand.

Jump Rope Reply Brief. If Jump Rope wins on this, an IPR petition that cancels claims would only cut-off prospective damages and injunctive relief.  The patentee could still recover pre-cancellation damages so long as the defendant failed to prove the claims invalid in district court at the higher standard.

= = =

The briefing also includes an important due process challenge — arguing that the use of IPRs to prevent infringement lawsuits violate due process.  In Oil States, various the patentee raised various challenges to the system, but did not bring a due process challenge. Oil States Energy Servs., LLC v. Greene’s Energy Group, LLC, 138 S. Ct. 1365 (“We emphasize the narrowness of our holding. . . . Oil States [has not] raised a due process challenge.”).

Here, the patentee makes two arguments:

  1. “First, front-line adjudicators are not sufficiently insulated from political forces. United States v. Arthrex, Inc., 141 S. Ct. 1970, 1993 (2021) (Gorsuch, J., concurring in part & dissenting in part) (‘The Court’s decision in Oil States allowing executive officials to assume an historic judicial function was always destined to invite familiar due process problems. . . . [P]owerful interests are capable of amassing armies of lobbyists and lawyers to influence (and even capture) politically accountable bureaucracies.’) (citations and internal quotation marks omitted).”
  2. “Second, by not permitting traditional live cross-examination of witnesses
    (instead, relying on written depositions), IPR procedures violate due process in view of the importance of the property right at issue. See Goldberg v. Kelly, 397 U.S. 254, 269 (1970) (‘In almost every setting where important decisions turn on questions of fact, due process requires an opportunity to confront and cross-examine adverse witnesses.’)”

Great questions from petitioner.

Robert Greenspoon (Dunlap Bennett) is counsel for the patentee Jump Rope Systems. Louis DiSanto (Banner Witcoff) is representing the accused infringer Coulter Ventures.   Their offices are a few blocks apart in downtown Chicago.

Federal Circuit Dataset & Stats: January 2023 Update

By Jason Rantanen

It’s time for the January 2023 Federal Circuit statistics update! As I’ve done for the last few years, below I provide some statistics on what the Federal Circuit has been doing over the past year. These charts draw on the Federal Circuit Dataset Project, an open-access dataset that I maintain that contains information on all Federal Circuit decisions and docketed appeals.  While previous versions of the dataset have been limited to merits decisions, this year we began including non-merits terminations as well.  Currently, all non-merits terminations from 2022 are included in the dataset.  We’ll be working backwards to add terminations from earlier years.

One of my goals with this dataset is to make it publicly accessible so that anyone can use it in their own research. A complete copy of this year’s release is archived at  In addition, you can access the dataset through a user interface via and generate your own subsets and graphs. A copy of the codebook is available at these locations as well. In addition, if you are a researcher who would like help using the dataset, please reach out to me – I’m happy to help out.

Onto the data!

Decision Numbers and Origins

Figure 1

Figure 1 shows the number of Federal Circuit opinions and Rule 36 summary affirmances by origin since 2010. These represent individual documents (i.e.: a single opinion or Rule 36) rather than docket numbers (which is how the Federal Circuit reports its metrics).

Once again, the highest number of merits decisions arose from the PTO. Overall, however, there was a substantial drop in the number of merits decisions: 532 in 2022, as compared with 643 in 2021.  Decisions from all origins actually dropped slightly, but the biggest drop was in the number of decisions arising from the PTO was the main reason: 147 in 2022 as compared with 216 in 2021. The direct cause of fewer decisions isn’t a mystery: as shown below, there was a big drop in appeals docketed at the Federal Circuit in 2021. Fewer appeals means fewer appellate decisions.

Opinions vs. Summary Affirmances

Figure 2

Figure 2 shows the number of opinions versus Rule 36 summary affirmances arising from the District Courts and PTO. In terms of absolute numbers, the court issued the fewest Rule 36 summary affirmances in appeals arising from these origins in several years.  In relative terms, 21% of the decisions arising from the district courts were disposed of through a summary affirmance while 42% of the Federal Circuit’s decisions arising from the PTO were summary affirmances.

What about the type of opinion that the court is issuing? For precedential opinions, Figure 3 shows that this is one area in which things are about the same as last year: the court issued slightly more precedential decisions arising from the district courts than in 2021 (52 vs. 47), and slightly fewer precedential decisions arising from the district courts (29 vs. 33). Rather, the drop in decisions arising from the PTO mostly manifested in terms of fewer nonprecedential opinions.

Figure 3

What about compared to the court’s overall decisions?  The number of precedential opinions issued by the court in 2022 was almost exactly the same as in 2021: 162 in 2022 as compared with 164 in 2021. But it is a drop from 2014-2020. (Note that this figure does not include Rule 36 summary affirmances).

Figure 4

General dispositions

Figure 5

In contrast with 2021, at which the Federal Circuit affirmed district court decisions relatively frequently (79%), in 2022 the court affirmed-in-full in appeals from the district courts just 57% of the time. Even including partial affirmances, the rate was lower than in recent years: it affirmed in full or part just 75% of the time. (The purple line indicates the average 68% affirmance rate over the 12-year time period). As a reminder, these graphs do not include petitions for writs of mandamus. In contrast, the court continued to affirm the PTO’s decisions at about the same rate as it has in recent years, affirming in full in 78% of its decisions.

Docketed Appeals

Figure 6 shows the number of docketed appeals by origin. These are are appeals filed at the Federal Circuit — the precursor to any decisions.  As Figure 6 shows, there was a substantial drop-off in appeals filed in 2021, followed by an increase in appeals filed in 2022, especially in appeals from the district courts (339 appeals filled in 2022 as compared with 286 appeals in 2021) and from the PTO (489 appeals filed in 2022 as compared with 402 appeals filed in 2021). Given what happened in appeals this year, I’d expect an increase in Federal Circuit decisions in 2023, recognizing that it takes about 13 months on average from filing to decision.

Figure 6

In addition to providing a picture of what’s being filed at the Federal Circuit, the docket dataset also allows us to match up the Federal Circuit decisions to other datasets of district court and PTO data, such as the USPTO Patent Litigation dataset and the Stanford NPE Litigation Dataset. If you’re interested in doing a deep dive into these areas, my research team and I used this data in a few papers this year:

Miscellaneous Dockets

One category of data that is not included in the above graphs is the data on petitions for writs of mandamus and petitions for permission to appeal. As in past years, nearly all of the miscellaneous matters consisted of Petitions for Writs of Mandamus, with a few Petitions for Permission to Appeal.  Figure 7 shows the numbers of dispositions of petitions for writs of mandamus over time.

Figure 7

In 2022, the court granted in whole or part 11 petitions for a writ of mandamus; fewer than 2021 (18), but at just as high a rate (42%). As in past years, the grants arise exclusively from petitions arising from the district courts.   Jonas Anderson, Paul Gugliuzza & I talk about this in more depth in Extraordinary Writ or Ordinary Remedy: Mandamus at the Federal Circuit, 100 Wash. U. L. Rev. 327 (2022)  

Additional terminations

Beginning in February 2022, the Federal Circuit began making all terminations of appeals available on its website. This is a terrific decision and is responsive to concerns about “missing” decisions that Merritt McAlister and I have each written about. That said, as I wrote about in my examination of the Federal Circuit’s decisions, the Federal Circuit has historically done a pretty good job most making merits decisions (i.e.: “Opinions” and “Rule 36” summary affirmances) available on its website, so many of these additional terminations consist of appeals that are dismissed pursuant to Federal Rule of Appellate Procedure 42(b). I supplemented what was on the court’s website with a collection of the additional January and February 2022 terminations from PACER, so all of the terminations for 2022 are in there.

Using data about these decisions, I was able to put together a graph showing how these appeals were disposed of. This graph differs a bit from the Federal Circuit’s own statistics because it’s by document rather than docket number, and (2) it is for the calendar year rather than the fiscal year. The purpose is to provide a sense of what happens to appeals other than those that result in merits decisions.

Figure 8

Close to 2/3rds of appeal terminations occurred in the context of an opinion (49%) or Rule 36 summary affirmance (14%). Most of the remainder were dismissals (32%). Of the dismissals, 63% were voluntary withdrawals (generally under to FRAP 42(b)). The remaining dismissals are for a variety of reasons, but typically due to a failure to prosecute the appeal, failure to appeal within the relevant time period, or lack of appellate subject matter jurisdiction.

To download the data for yourself, visit the dataverse or go to I’ve also saved a copy of my Excel workbook with the graphs on the Dataverse archive. It contains the specific parameters that I used to generate these graphs.

Three New Supreme Court Cases:

by Dennis Crouch

  1. Vidal v. Elster.  Elster is seeking to register the mark TRUMP TOO SMALL, but was initially rebuffed because the law prohibits registration of a mark consisting of the name of a particular individual. 15 U.S.C. 1052(c).  On appeal though, the Federal Circuit found such a restriction unconstitutional — especially in this situation where the mark forms a criticism.  The court’s decision follows the logic of two recent Supreme Court cases on point: Tam (the SLANTS – disparaging marks) and Brunetti (FUCT – scandalous marks).  In its petition, however, the US Gov’t tries to distinguish those viewpoint cases from this one that arguably does not involve viewpoint discrimination. Question presented: “Whether the refusal to register a mark under Section 1052(c) violates the Free Speech Clause of the First Amendment when the mark contains criticism of a government official or public figure.”
  2. Nike v. Adidas: This one is not yet a petition, but in an extension request, Nike indicated its plans to petition this case.  The basic issue is whether the IPR statute permits the Board to raise patentability issues sua sponte with regard to substitute claims.  See 35 USC 316(e) (“the petitioner shall have the burden of proving a proposition of unpatentability by a preponderance of the evidence”).
  3. Thryv v. Click-to-Call: This is the sister case of the IPR previously before the Supreme Court. The IPR only canceled some of Click-to-Call’s claims. The district court then invalidated the remaining claim in suit.  However, on appeal, the Federal Circuit ruled that the invalidity challenge was estopped under Section 315(e).  Thus, the petition in this case is likely to raise the same question raised by Apple in the CalTech case. For now though, the petitioner is simply asking for a 30-day extension of its due date.

Chamberlain Closes on Overhead Door

The Chamberlain Group v. Overhead Door Corp., 21-CV-00084 (E.D. Tex. 2023)

Overhead door won a jury verdict in this case back in March 2022.  However, Judge Gilstrap ordered a partial new trial because Overhead Door had failed to disclose key features of its products until just before trial. New Jury, New Verdict.  Second time around, the new jury found the asserted claims valid and not infringed — setting the royalty at $43 million.

U.S. Patent No. 8,587,404.

4. A movable barrier system with a moving-barrier imminent motion notification, the system comprising:

a movable barrier operator connected to close a movable barrier;

the movable barrier operator configured to receive a transmitter identification code from a transmitter as part of a communication from the transmitter triggered in response to a first user input at the transmitter, the communication comprising a command to close configured to effect closing of the movable barrier, the movable barrier operator also configured to determine whether to close the movable barrier in combination with operating a moving-barrier imminent motion notification in response to receipt of the command to close the movable barrier based at least in part on the transmitter identification code;

the movable barrier operator configured to determine whether to close the movable barrier without operating the moving-barrier imminent motion notification based at least in part on the transmitter identification code.


Rep. Issa – House IP Leader

Ryan Davis at IP360 is reporting that Rep. Darryl Issa is the new chair of the House Subcommittee on Courts, Intellectual Property, and the Internet. He was previously Chair 2015-2019.   Issa has been called-out by the group US Inventor for his previous failure to focus on their particular concerns.   He has not announced particular plans for the committee. Sen. Chris Coons is most likely to take over as chair of the parallel Senate Committee following Sen. Leahy’s retirement.

Jack Daniels vs Bad Spaniels: Funny Jokes and Free Speech

It is hard for me to believe that the US Supreme Court is hearing the case of Jack Daniels vs Bad Spaniels. For those who don’t know, Jack Daniels is a form of Whiskey.  VIP Products makes and sells a squeaking dog toy known as “bad spaniels.” The setup here is a humorous parody, but JD is not laughing.

Jack Daniels sent a cease-and-desist letter to VIP who then filed a declaratory judgment action in Arizona. The district court sided with JD on both TM infringement and dilution and issued an injunction to stop ongoing sales and distribution.  (The excrementory references in Bad Spaniel also led to tarnishment conclusions).  On appeal though, the 9th Circuit identified the toy as an “expressive work” entitled to speech protections under the First Amendment of the US Constitution and ordered the lower court to apply an enhanced infringement analysis stemming from Rogers v. Grimaldi, 875 F.2d 994 (1989).  Under Rogers, the court needs to consider the expressive relevance of the accused work and whether it is “explicitly” misleading.  With regard to dilution, the appellate court found that the dog toy was not actually making commercial use of the JD mark.  Although the toy was being sold in commerce, the JD mimicry was for humourous speech purposes rather than simply commercial.

The Supreme Court granted certiorari and the briefing is ongoing.  Typically, the most important amicus brief in a private case is that filed by the U.S. Government.  Here, the USPTO and DOJ joined together to file a brief strongly supporting the mark holder — writing that the 9th Circuit decision “is egregiously wrong.” The Gov’t is particularly concerned that a funny joke will be an excuse to allow infringement.  Although humorous parody should be a factor in the likelihood-of-confusion analysis, the Gov’t argues that it should not be a determinative “get-out-of-the-Lanham-Act free card.”  On the dilution side, the Gov’t argues that Congress expressly set the rules, including a defense that the accused use is not being used as a mark.  The Gov’t argues here that the Ninth Circuit ignored that provision and instead created its own non-statutory rule regarding the commercial nature of the humor being used.

The Government’s basic argument here is that free speech concerns are properly incorporated into the infringement analysis and should not be given a separate overlay.  The result then is a holistic balancing of speech interests against the misleading nature of a product.  “The Ninth Circuit’s reasoning means that virtually any humorous pirating of a trademark will be “expressive” and thus qualify for heightened First Amendment protection, no matter how misleading.”

The briefing also highlights some concerning uses of marks to sell marijuana products, such as the Oreo knock-off below.  These don’t really seem humorous, but who am I to know?

Read the Gov’t Brief here.  One note, in the case, the appellate court did not expressly consider Bad Spaniels under a more traditional parody test.  The Gov’t suggested vacatur and remand to the 9th Circuit to reconsider on those grounds.

Copyright and AI – Zarya of the Dawn

by Dennis Crouch

In a prior post, I mentioned that the Copyright Office had canceled the registration for “Zarya of the Dawn,” a book purportedly created mainly by AI.  That was in error apparently generated by the Office’s new Copyright Public Records System.    The attorney for the human author – Kristina Kashtanova – contacted me to point out the error and you can see that the errors have been corrected. The copyright is currently registered.

A post shared by Kris Kashtanova (@kris.kashtanova)

That said, the Copyright Office has initiated a cancellation process for the work.  In a responsive filing, her attorney Van Lindberg walks through her creation and makes the case that all aspects of the book, even computer generated images, are copyrightable.

In addition to the copyrightability of the Work as a whole, each individual picture is itself the result of a creative process that yields a copyrightable work. Kashtanova could extract any single image from the Work and submit it to the Office and correctly assert her authorship of that image.

Unlike the “autonomously generated” picture known as “A Recent Entrance to Paradise,” all the images in the Work were designed by Kashtanova. The visual structure of each image, the selection of the poses and points of view, and the juxtaposition of the various visual elements within each picture were consciously chosen. These creative selections are similar to a photographer’s selection of a subject, a time of day, and the angle and framing of an image. In this aspect, Kashtanova’s process in using the Midjourney tool to create the images in the Work was essentially similar to the artistic process of photographers – and, as detailed below, was more intensive and creative than the effort that goes into many photographs. Even a photographer’s most basic selection process has been found sufficient to make an image copyrightable. The same reasoning and result should apply to the images in Kashtanova’s Work.

An Update on AI Inventorship and Authorship Cases

by Dennis Crouch

In 2022, the Federal Circuit held that an invention is only eligible for a US patent if a human conceived of the invention. Thus, no patents for invention wholly conceived by artificial intelligence.  Thaler v. Vidal, 43 F.4th 1207 (Fed. Cir. 2022).  Thaler’s petition for writ of certiorari to the US Supreme Court would have been due last week, but Thaler was able to obtain an extension with the petition now being due March 19, 2023.  Thaler’s main attorney throughout this process has been Professor Ryan Abbott. The team recently added appellate attorney and Supreme Court expert Mark Davies to the team, and so it should be a great filing when it comes.  The motion for extension explains that the case presents a fundamental question of how the law of inventorship should apply “to new technological methods of invention.”

Specifically, this case arises from the Federal Circuit’s denial of a patent to an invention created by an artificial intelligence (AI) system, holding that an AI system is categorically unable to meet the definition of “inventor” under the Patent Act. The questions presented in Dr. Thaler’s petition will have a significant impact on Congress’s carefully balanced scheme for protecting the public interest in promoting innovation and ensuring the United States’ continued international leadership in the protection of intellectual property.

Extension Motion.  Part of the justification for delay is that Dr. Thaler and his attorneys have a parallel copyright case pending.  Thaler attempted to register a copyright for a computer-created work of art. But, the copyright office refused once Thaler expressly stated that there was no human author.  Thaler then sued in DC District Court.  Most recently, Thaler moved for summary judgment, presenting the following question for the district court to decide:

With the facts not in dispute, this case boils down to one novel legal question: Can someone register a copyright in a creative work made by an artificial intelligence? The plain language and purpose of the Copyright Act agree that such works should be copyrightable. In addition, standard property law principles of ownership, as well as the work-for-hire doctrine, apply to make Plaintiff Dr. Stephen Thaler the copyright’s owner.

THALER v. PERLMUTTER et al, Docket No. 1:22-cv-01564, Paper No. 16 (D.D.C. Jan 10, 2023).  The image, reproduced below from the complaint is known as “A Recent Entrance to Paradise.” (Registration Application #1-7100387071).

In another recent example, the Copyright Office has also canceled copyright registration for Zarya of the Dawn, apparently because of its AI-created status.

Mandamus Reasonably Denied

In re General Motors Co. (Fed. Cir. 2022)

Without much pretense, the Federal Circuit has rejected GM’s petition to the Federal Circuit seeking transfer of its case out of the Western District of Texas.  In 2021, Intellectual Ventures (IV) sued GM for infringement of twelve different patents — all focusing on features of GM’s OnStar service.  GM wanted the case to moved up to Michigan on convenience grounds, but Judge Albright Refused.  In particular, Judge Albright noted that GM has a major IT Innovation Center in WD Tex (Austin) that includes potential witnesses.  On mandamus, the Federal Circuit refused to disturb this holding.

In the short opinion, Judge Stark found Judge Albright’s findings reasonable and relevant. In particular, the court noted the following:

GM employees in the Western District of Texas with relevant and material information;

Electronic evidence in Michigan can be accessed by GM from its offices in the Western District;

The Western District (and not Michigan) has the power to compel one of the inventors to testify; and

The Western District has a strong local interest  because of GM’s significant presence, including many who devlop/sell the accused products.

Slip. Op.  Before transferring a case on convenience grounds, the district court must determine that the proposed district is “clearly more convenient.” This is already quite a high standard that provides substantial discretion to the district court.  But, the mandamus standard is even higher and requires an extraordinary situation involving clear error and substantial resulting harm that cannot be resolved later on appeal.  Here, the appellate court found that lacking because Judge Albright’s decision provides a plausible basis to conclude that E.D. Michigan was not clearly better.

The Federal Circuit decided this one on the briefs. Steve Baskin (King & Spalding) filed the petition on behalf of GM. Jon Waldrop (Kasowitz Benson) was lead attorney for IV.



Laching-On to Inexcusable Behavior

Guest Post by Jordan Duenckel.  Jordan is a second-year law student at the University of Missouri, head of our IP student association, and a registered patent agent. 

The Federal Circuit released its opinion in Personalized Media Communications, LLC, Vs. Apple Inc., Docket No. 2021-2275 on January 20, 2023, in a dispute involving an alleged pattern of inappropriate conduct during patent prosecution. In a split decision, the Federal Circuit ruled that the district court did not abuse its discretion in declaring a patent unenforceable based on prosecution laches.

Apple FairPlay uses digital rights management (DRM) to limit user access. Specifically, FairPlay encrypts data and uses “decryption keys” to control decryption. As an additional added layer of security, Apple further encrypted these decryption keys and this further encryption is the basis for the patent infringement suit brought by Personalized Media Communications, LLC (PMC) based on PMC’s U.S. Patent No. 8,191, (the “’091 patent”). The jury reached a unanimous verdict and awarded $308 million to PMC for infringement of claims 13-16. Despite the favorable verdict on infringement, the district court eventually sided with Apple by holding the ‘091 patent unenforceable based on the equitable affirmative defense of prosecution laches. Prosecution laches requires proving two elements:

  1. The patentee’s delay in prosecution must be unreasonable and inexcusable under the totality of circumstances; and
  2. The accused infringer must have suffered prejudice attributable to the delay.

Hyatt v. Hirshfeld, 998 F.3d 1347, 1359–62 (Fed. Cir. 2021).

PMC’s applications were pending for 16 years before the claims were presented for examination.  During that process, PMC filed several thousands of claims.  PMC’s application was one of the few pre-GATT applications still pending at the USPTO, having been filed on the June 7, 1995, deadline.  The legal result is that the patent term extends 17 years from its 2012 issuance date (34 years from the filing date). But, the district court concluded that equity could not maintain the result because PMCs delays were unreasonable and inexcusable.

PMC raised a number of justifications on appeal, perhaps most interesting is that PMC’s prosecution strategy was in line with the “Consolidation Agreement” it made with the PTO. The agreement was part of the USPTO’s efforts to move out these old cases.  According to the procedure, where PMC was to designate “A” applications and “B” applications, with the PTO prioritizing “A” applications. Rejected claims would transfer to the corresponding “B” application and prosecution of “B” applications was stayed until the corresponding “A” application issued. This A to B process, in effect, allows PMC to delay the examination of applications and allows two chances for examination without paying a continuing examination fee.

On appeal, the majority, written by Judge Reyna and signed by Judge Chen, did not see this scheme as an excuse, but rather as further evidence of PMC’s inexcusable behavior in the prosecution process. In dissent, Judge Stark suggested that Apple had failed to show prejudice attributable to PMC’s delay.

Typically, an accused infringer can show prejudice based upon investment or use of “the claimed technology during the period of delay.” The majority concluded that Apple necessarily invested in FairPlay during the delay since it launched the product in 2003. The dissent focuses on the timeframe of the PMC’s conduct, finding that it was PMC’s pre-2000 conduct that was unreasonable while the post-2000 conduct involved more routine aspects of patent prosecution’s back-and-forth nature.   But, Apple did not prove that it was prejudiced by the pre-2000 conduct.

My thoughts: Prosecution laches is a remedy meant to address abuse of the patent system and necessarily must be flexible to meet ever-changing strategic conduct. PMC employed a business strategy deliberately aimed at creating a labyrinth of patent protection extending beyond the statutory twenty years, directly stating that the goal was patent coverage extending 30 to 50 years.  Further, PMC was unable to provide a legitimate purpose for the delays that aligns with the general goals of patent protection.

To me, the prejudice suffered by Apple is clear. At the time that Apple was developing FairPlay, they were unable to know the full scope of PMC’s patent protection. The chronological line drawing that the dissent favors ignores the practical effects of PMC’s ongoing deliberate business strategy.  Although the unreasonable acts may have taken place prior to 2000, the impact of those actions continued well beyond. The attempt to distinguish post-2000 activities as prejudicial or not in isolation avoids the totality of the circumstances that equitable remedies like prosecution laches are meant to address.

Request for Comments on USPTO Initiatives to Ensure the Robustness and Reliability of Patent Rights

Feb 1, 2023, is the new deadline for providing comments to the USPTO on this RFC.

Topics: The USPTO invites written responses to the following questions and requests. Commenters are welcome to respond to any or all of the questions.

1. Identify any specific sources of prior art not currently available through the Patents End-to-End Search system that you believe examiners should be searching. How should the USPTO facilitate an applicant’s submission of prior art that is not accessible in the Patents End-to-End Search system ( e.g., “on sale” or prior public use)?

2. How, if at all, should the USPTO change claim support and/or continuation practice to achieve the aims of fostering innovation, competition, and access to information through robust and reliable patents? Specifically, should the USPTO: (more…)

Guest Post by Prof. Hrdy & Dan Brean: The Patent Law Origins of Science Fiction

Guest post by Camilla A. Hrdy, Professor of Intellectual Property Law at University of Akron School of Law, and Daniel H. Brean, Senior In-House Intellectual Property Counsel, Respiratory Care, Philips.

Are inventions described in works of science fiction patentable? The answer is usually no, and for good reason. Some of the most beloved fixtures of the genre—time machines, faster-than-light space travel, teleportation, downloading memories, copying a consciousness, etcetera—are impossible or not yet possible when described by the author. This sort of science fiction is not patentable because it cannot logically be enabled or have credible utility when the patent is filed.

For similar reasons, science fiction is rarely cited as prior art against later patent filings. Science fiction can qualify as prior art under § 102(a) as a “printed publication” or as “otherwise available to the public.” It can be especially useful as “obviousness” prior art because, to quote the Federal Circuit, a “reference that does not provide an enabling disclosure for a particular claim limitation may nonetheless furnish the motivation to combine, and be combined with, another reference in which that limitation is enabled.” Raytheon Techs. Corp. v. General Electric Company, 993 F.3d 1374 (2021). However, science fiction is unlikely to be cited during examination.[1] Examiners lack the time and energy to search for on-point science fiction where there is so much more (and better catalogued) prior art among patents and scientific publications. Applicants, for their part, are not required to disclose prior art that is not material to patentability or that is cumulative of other prior art they’ve already provided. See

It may surprise you, then, to learn that the genre of science fiction is deeply indebted to patent law and patent theory. In our new paper, The Patent Law Origins of Science Fiction, available at, we show that science fiction as a literary form was originally premised on the idea that works of science fiction are like patents. They disclose useful technical information that can give readers a “stimulus” to perfect the invention and figure out how to make it work.

The person responsible for this comparison was the so-called “father” of science fiction, Hugo Gernsback. He started the first exclusively-science fiction magazine, called Amazing Stories, in 1926. The Hugo awards, given to the best works of science fiction and fantasy writing, are named after him.

Gernsback was also an inventor and serious scientific thinker in his own right. He died with over thirty patents to his name. In the early 1900s, he started a radio and electronics equipment company in New York. To support his business, he initially published catalogs for mail-order electrical components, but the catalogs soon morphed into full-sized magazines with titles like “Modern Electrics, marketed to inventors and amateur “tinkerers.” Hugo Gernsback, The Perversity of Things, Grant Wythoff ed. (University of Minnesota Press 2016). His magazines were full of information about patents and advice on patenting—which Gernsback deemed an essential step in the commercial success of any new invention.

At first, Gernsback started publishing science fiction stories—which he then called “scientifiction”—to fill space in his electrical magazines. These stories were sometimes little more than a few paragraphs of exposition about some speculative new device that might be used in the future, plugged into a generic adventure plot. For example, one story featured a genius from the future using (what we now call) “radar” to track down a Martian who had kidnapped the protagonist’s love interest in a Space Flyer. Despite the fictional elements, science and scientific plausibility were still all-important. Gernsback was fond of saying the recipe for good scientifiction was 25% science and 75% literature.

Readers loved it, and Amazing Stories was born. Gernsback knew he was on to something, and he frequently published editorials expounding on the virtues of scientifiction. These editorials, along with his unpublished manuscripts, reveal Gernsback’s theory that a good science fiction story is like a patent, but a much more “palatable” read. Although he did not articulate it in precisely the same terms, Gernsback’s justification for scientifiction echoes the language of patent law’s disclosure theory. Scientifiction, he wrote, provides both knowledge and “stimulus.”[2] It inspires “seriously-minded” readers to learn about science and technology, and it supplies the “inventor or inventor-to-be who reads the story” with “an incentive” to “realiz[e] the author’s ambition” by perfecting the author’s science fictional inventions in the real world. Gernsback often drew the analogy to patents quite explicitly. The science fiction author, in his framework, was “an original inventor,” like the named inventor on a patent. The readers who got the author’s invention to work were like “manufacturers” who buy patents and commercialize the inventions therein “with but a few changes.” They were just there to profit from the author’s grand ambitions.

Over time, Gernsback developed a crazy idea. If science fiction authors are “inventors” who inspire others to reduce their inventions to practice, then shouldn’t science fiction authors be able to get patents for their prescient descriptions of future inventions? And shouldn’t science fiction serve as prior art against other peoples’ patents? In 1952, just after Congress had modernized the Patent Act, Gernsback made these ideas public. In a speech he gave to the World Science Fiction Convention in Chicago, he proposed that Congress should reform patent law (again) to give science fiction authors the ability to apply for “Provisional Patents.”

Gernsback’s Provisional Patents were not at all like today’s provisional patent applications. Compare 35 U.S.C. § 111. His Provisional Patents would have given science fiction authors thirty extra years in which to demonstrate their science fictional inventions worked. If they could do so, the Provisional Patent would be converted into a normal patent, presumably in force for the full patent term (which at that time meant 17 years). Otherwise, it would be abandoned. This proposal was not adopted and, we presume, was never seriously considered.

In the same speech, Gernsback also proposed that authors and publishers should start identifying works of science fiction that contained “new and feasible” inventions, so that they could send these selected works to the patent office. Gernsback’s hope was that the patent office would be deluged with science fiction and have no choice but to start reviewing and citing science fiction more often as prior art. This idea had more grounding in current law than Gernsback’s Provisional Patents, but it was not adopted either. Mechanisms for getting prior art to the patent office have certainly improved since Gernsback’s time. But we still don’t send the patent office curated collections of science fiction.

Gernsback’s ideas were iconoclastic, and his proposal to make Provisional Patents available for inventions that are not yet reduced to practice is deeply troubling from a policy perspective. Science fiction authors who make reasonably accurate predictions about future technological developments would gain the ability to sue the very people who figure out how to make those technologies. Imagine the effect on the computer industry if a science fiction author had been able to reserve the right to patent a supercomputer in the early 1920s, and then converted this into a full patent in the 1950s…

But taking Gernsback’s ideas seriously generates some surprising insights. Science fiction—of the type that Gernsback and “hard sf” writers like Jules Verne and Isaac Asimov wrote—has more in common with patents than it might seem. Publishing a work of science fiction confers no exclusive rights on the inventions it contains. But, like patents, works of science fiction are documents that disclose potentially useful information about science and technology. Like patents, science fiction stories can describe inventions that have not literally been reduced to practice; they can leave many details to skilled artisans to figure out. Both science fiction readers and patent examiners are also supposed to suspend disbelief, presuming the inventions described on the page are based on plausible scientific principles. See, e.g. In re Cortright, 165 F.3d 1353 (1999). If we think patents are an important part of the innovation ecosystem because they disseminate useful technological teachings and insights, then science fiction might be too.

How often science fiction influences innovation is an extremely interesting question. Ironically, the patent record itself is a great source of data with which to test Gernsback’s theories. In fact, one of Gernsback’s more questionable assumptions was that profit-hungry readers are “continuously” filing patents on inventions they learned about in science fiction. They remember the idea, “lard it with a few of [their] own, patent it and start a new billion dollar industry on it.” Regardless of whether that is true, if someone is inspired by science fiction to make an invention in the real world, then we should sometimes see evidence of this in the patent record.

Formal prior art citations to science fiction are rare for the reasons we said above. But we can find circumstantial evidence of science fiction’s influence by searching patents. For example, specifications sometimes reference science fiction in the body, even if they don’t formally cite to science fiction as prior art. Search the patent record for “Asimov, “Three Laws of Robotics,” or “Star Trek,” and you’ll see what we mean. We can also find more direct evidence of influence—situations where inventors expressly state that they got their inspiration from science fiction. For this, though, we usually have to look outside the patent record. Inventors’ autobiographies, interviews, speeches, and marketing efforts can reveal clues. For example, Neil Stephenson’s 1992 book Snow Crash features a virtual world called the Metaverse. Facebook and other tech companies are making their own virtual worlds and calling them by the same name. That, along with direct statements from employees that Stephenson is “our inspiration,” helps support that there was some degree of influence. Steven Levy, Neal Stephenson Named the Metaverse. Now, He’s Building It, Wired (Sept. 16, 2022).

This is surely sometimes independent invention, the result of multiple inventors responding to the same technological developments and contemporary trends. Mark A. Lemley, The Myth of the Sole Inventor, 110 Mich. L. Rev. 709 (2012). But sometimes it is not. Despite all the legal and practical barriers, science fiction appears in the patent record. It was important enough to play some small part in the journey that culminated in the invention. At the end of the day, there is only one explanation for this: Some inventors read science fiction, and some science fiction matters to those people. Its ideas inspire them in ways that traditional sources (including patents) do not. Gernsback put it best. Science fiction “fires the reader’s imagination more perhaps than anything else of which we know,” leaving readers “deeply thrilled[,]” as their “imagination is fired to the nth degree[.]” Few people would ever say that about reading patents.

Even if science fiction does not directly influence someone to make the precise inventions it discloses, it can impact peoples’ career choices, inspiring them to go into science or pursue a general line of inquiry. It can inspire them to go to space. Kristen Houser, Science fiction doesn’t predict the future. It inspires it, BigThink (Oct. 23, 2021). Arthur C. Clarke went so far as to say that “by writing about space flight we have brought its realization nearer by decades.” In Clarke’s view, science fiction both imparted useful technical information and acclimated readers to the possibility of space flight, priming them to support and accept the novel technology when it arrived.

Gernsback’s science fiction-as-patent theory also contains some wisdom for science fiction writers. A little more patent-style “enablement” in science fiction might do more for innovation than science fiction writers want to believe. There is nothing wrong with fantasy and so-called speculative fiction. It is often tremendously entertaining. But we call it science fiction (and thankfully not scientifiction) for a reason: it is based on kernels of real science. To quote Gernsback, what makes science fiction different from romance and adventure stories is that it is grounded in “scientific fact” and has the potential to be “prophetic.” It might one day come to pass. Science fiction authors who work to “enable” their stories, even just a bit, have a better chance to give a stimulus to readers to reduce their inventions to practice. There are many, many authors who already do this, and do so without compromising the quality of the narrative. They might literally affect the future in the way we imagine all inventors hope their patents will. See;

[1] This is not to say it does not happen. In litigation, defendants have stronger incentives to find science fiction prior art and use it to build a case for invalidity. For example, in 2011, during the “smart phone wars,” Samsung argued Apple’s iPad design patent was anticipated by what appear to be “tablet” computers in scenes from Stanley Kubrick’s 1968 film 2001: A Space Odyssey.

Director Review: Petitioner must Prove its Case

by Dennis Crouch

Apple Inc. v. Zipit Wireless, Inc., 2022 WL 18108215 (PTO Dir., Dec. 21, 2022)

Back in December, Director Vidal issued an important director review decision holding an IPR challenger must prove that the challenged claims are invalid, even if the patentee raises no defense.  The PTAB appears to have incorrectly treated the situation as more of a default judgment even though the patentee had not expressly abandoned.

Apple filed three IPR petitions against each of two Zipit patents.  The PTAB instituted IPR proceedings in all six.  At that point, Zipit filed patent owner responses in two of the cases, but not in the other four cases.  In its final written decision, the PTAB did not consider the merits of the case, but simply concluded that the patent owner had “abandoned the contest” and treated their lack of opposition as a “request for adverse judgment under 37 C.F.R. § 42.73(b).”

In a sua sponte review of the record, Dir. Vidal noted that Counsel had not expressly abandoned the case, and during the hearing stated that judgment for Apple is appropriate “if the Board determines that they have met their burden of proof with respect to those claims.”  Vidal concluded that “Patent Owner’s non-opposition was contingent on the Board determining that Petitioner met its burden of proving by a preponderance of the evidence that the challenged claims are unpatentable.” As such, the Board must consider the evidence presented by Apple and determine whether it meets the statutory burden of providing “unpatentability by a preponderance of the evidence.” 35 U.S.C. 316(e).

Supreme Court asked to Review Federal Circuit’s Judicial Shell Game

by Dennis Crouch

Novartis Pharms v. HEC Pharm (Supreme Court 2023)

Some drug treatments perform better if the patient starts with a loading dosage before shifting to the regular daily amount. But, loading dosages can be risky because of the high dosage and because of the greater likelihood of mistakes.  Novartis was able to configure a multiple sclerosis treatment plan without the loading dosage.  Its claims require the administration of fingolimod “at a daily dosage of 0.5 mg, absent an immediately preceding loading dose regimen.” US Patent No. 9,187,405. The problem for Novartis is that its original priority application filings did not say anything positive or negative about a loading dosage, and the court eventually rejected the priority claims and thus invalidated the patent claims.

Novartis almost walked away a winner.  In the ANDA litigation, Judge Jordan (D.Del.) found the claims valid and infringed by HEC. On appeal Federal Circuit Judge O’Malley penned the majority opinion affirming the Novartis win. Judge Linn sided with O’Malley, with Chief Judge Moore in dissent.

But then an odd sequence of events occurred: (1) in February 2022, HEC filed a petition for panel rehearing; (2) but before the panel could rule on the motion, Judge O’Malley retired.  (3) At that point, Judge Hughes was added to the panel; and (4) Judge Hughes sided with Chief Judge Moore’s position.  The modified panel then issued a new opinion with Judge Moore’s prior dissent effectively becoming the majority, and Judge Linn now writing in dissent.  What made this more surprising was that the Federal Circuit had not provided any indication of Judge Hughes’ substitution.

Novartis petition for certiorari addresses both the procedural judicial shell game and the substantive written description question. Questions presented:

1. Whether 28 U.S.C. § 46 and principles of sound judicial administration preclude a court of appeals from adding a new judge to form a new panel and redecide a case after an original three-judge panel has already decided the case and entered its judgment.

2. Whether 35 U.S.C. § 112 should be interpreted consistent with its plain text as requiring that a patent specification contain a “written description of the invention” in a form that need only be understandable to “any person skilled in the art,” or whether the court of appeals properly read in a heightened requirement that allows it to deem the specification inadequate on de novo review and displaces the perspective of a person skilled in the art.

Novartis Petition for Cert 2023.   The Supreme Court will decide the Amgen enablement case later this term, but recently denied certiorari in the written description case of Juno v. Kite.

My thoughts: I think that Chief Judge Moore probably has the best argument on the merits of the written description question.  If you are going to claim some particular element of the invention (and use it to overcome the prior art), that element should be introduced at some level in the original specification.  But, written description is a question-of-fact, what that means is that the appellate court cannot simply substitute its decision in place of that of the district court. Rather, the district court’s finding of facts should be affirmed barring some clear error or abuse of discretion. The case is close enough here that I would not find a clear error by the district court judge.  The panel switch also smells very bad to me.

Pundits will tell you that the use  of top Supreme Court counsel helps get the court’s attention. That bonus is probably mostly because of their skill at framing the case, but their reputation within the Court probably also plays a role.  In this case though Novartis appears to go overboard and included a host of top Supreme Court counsel, including Deanne Maynard (MoFo), Willy Jay (Goodwin Procter), and Thomas Hungar (Gibsun Dunn), all of whom have successfully argued numerous cases before the Court.

Supreme Court Taking Additional Look at Apple’s Estoppel Petition

by Dennis Crouch

The Supreme Court has added a fourth case to its list of potentials for 2023: Apple Inc., v. California Institute of Technology, Docket No. 22-203.  The case is extremely important for our patent system because it could define key aspects of the interplay between inter partes review (IPR) proceedings and parallel district court litigation.

IPR Estoppel Provision: In traditional patent infringement litigation, accused infringers almost always raise invalidity defenses — arguing that the patent fails to satisfy the conditions of patentability set forth in the Patent Act.  For the past decade, IPRs have offered an additional powerful tool to challenge validity.  As the IPR system was being developed, patent holders were concerned about repeat harassment and argued that patent challengers should be required to choose their battleground: either the PTAB or Court, not both.   Aspects of the eventual compromise are codified in the estoppel provision of 35 U.S.C. 315(e)(2).  The statute becomes effective once an IPR reaches a final written decision as to some claim in the challenged patent. At that point, the IPR petitioner is prohibited from asserting in court that any challenged claim is “invalid on any ground that the petitioner raised or reasonably could have raised during that inter partes review.”  Id.  The question in the case is statutory interpretation – what did Congress mean by “could have raised during that inter partes review”?

Apple lost its IPR against CalTech’s patent and subsequently attempted to maintain further obviousness arguments in the parallel infringement litigation. The district and appellate courts applied 315(e)(2) estoppel to prohibit those additional obviousness arguments — concluding that Apple reasonably could have raised them in its initial IPR petition.  Apple’s appeal to the Supreme Court argues that the Federal Circuit misconstrued the statute. Apple’s argument hinges on three key points:

  1. The statutory estoppel applies only to grounds that could have been raised “during” the IPR;
  2. The IPR begins only at the point where the PTAB grants the petition to institute an IPR; and
  3. Once the IPR is instituted, the petitioner is barred from raising new grounds (except for rebuttal-type issues).

The Federal Circuit’s error (according to Apple) is that the court found that estoppel applies to any ground that could have been raised in the petition. But, the petition is pre-IPR and thus not “during” the IPR as the statute requires.  The petition for writ of certiorari asks the following question:

Whether the Federal Circuit erroneously extended IPR estoppel under 35 U.S.C. § 315(e)(2) to all grounds that reasonably could have been raised in the petition filed before an inter partes review is instituted, even though the text of the statute applies estoppel only to grounds that “reasonably could have [been] raised during that inter partes review.”


What’s the news: The Supreme Court has issued a CVSG – Call for the Views of the Solicitor General – in the case.  What this means is that at least four justices think that case has potential but that they would like to hear the Biden Administration’s views on whether this is an appropriate vehicle. The SG’s office is already working on three other briefs. Two focus on eligibility (Interactive Wearables & Tropp), and the other addresses the PTO-FDA interaction involving skinny-label infringement (Teva v. GSK).

My view on the estoppel issue:

  1. Point for CalTech: The Federal Circuit’s solution here is the better policy.  Parties should not be given repeated affirmative opportunities to attempt invalidation of the same patent claims. Rather, the process should follow the general use-it-or-lose-it rule of litigation that forces parties to bring their best arguments to the table and see if they are good enough.  Here, Apple made a strategic decision to bring certain arguments to the PTAB — most likely because they were the best arguments.  It doesn’t help anyone to now let them bring on the third-string as a measure of patent invalidity.
  2. Point for Apple: A pure textual reading of the statute favors Apple. If the IPR does not start until initiated, “during” the IPR would not include any petition-stage actions.
  3. Match for CalTech: Apple’s reading removes essentially all meaning from the “reasonably could have raised” provision since petitioners basically cannot add any new grounds once the petition is granted. The statute’s purpose though was to prevent abusive and serial patent challenges.

I always hope that the Supreme Court takes patent cases because of both the drama and potential for meaningful and positive reform.  Likewise, I hope that the court takes this case, but then affirms.

Push-Down on Drug Patents and Drug Pricing

by Dennis Crouch

Over the past several months, the USPTO and FDA have been collaborating with the purpose of promoting competition and lower drug prices in the US.   This week (Jan 19), the USPTO is holding a 7-hour joint listening session hosted by USPTO Director Kathy Vidal and FDA Commissioner Robert Califf.  [Register and see the Agenda here]

The session has three key substantive areas:

  1. The extent and impact of pharmaceutical and biotech companies acting in a two-faced manner: Arguing to the USPTO that their treatments represent major changes from what was previously done (and thus patentable); while simultaneously arguing to the FDA that then later arguing that these same treatments are quite similar to what is already on the market (and thus safe for use).
  2. The extent that pharmaceutical and biotech companies are improperly gaming the patent system and then using those games to justify strong protections under Hatch-Waxman and the BPCIA.
  3. How can the Orange Book process be improved to protect innovation while simultaneously improving competition?  Prof. Jay Thomas’s remarks here are on point: “Despite their [extraordinary] impact, Orange Book patent listings receive no FDA oversight.”  PTO-P-2022-0037-0010.

The thrust of this entire gambit from the administration level is to reduce drug prices.  But, once we drop down to the PTO/FDA level, the close industry relationship suggests to me that agency officials will be keenly aware of the potential negative impacts of any action on pharma innovation.

The key leadoff speaker is Hastings Law Professor Robin Feldman whose work argues that the system is broken in myriad ways.  George Mason Prof. Adam Mossoff will provide a high-level counterargument, and several others will talk through complications. In particular, I always learn a lot hearing from Corey Salsberg (Novartis), Sean Tu (WVU), and Jay Thomas (G-Town)

While this is a joint event, both agencies (along with several other federal agencies) are also operating unilaterally to address the high cost of healthcare in America.  In particular, the FTC/DOJ are using antitrust tools to push against monopoly-level pricing even for drug products whose use is protected by patents.

Although no direct action items are expected to come out of this event,  I see all of this as quite a big deal as the various players work to establish their narrative.



Trade Secrecy Rising

by Dennis Crouch

A continuing trend in American law is the rise of Trade Secrecy as a powerful form of intellectual property.

The FTC and Biden Administration have called for eliminating employee non-compete agreements, which will strengthen the hard push for trade secrecy.  Most trade secret claims involve former employees moving to competitors.  If contracts limiting those transitions are unenforceable, more weight will almost certainly fall on trade secrecy rights.

Recently, President Biden also signed into law the Protecting American Intellectual Property Act of 2022.  Despite its broad name, the new law focuses entirely on international trade secrecy issues.  In particular, the law authorizes the US President to place sanctions on foreign entities that engage or benefit from “significant theft of trade secrets of United States persons.”   The law has a two-step approach: (1) the President must provide Congress with a report of violators; and (2) the President must then put sanctions on the violators (with the exception that sanctions can be waived if in the national interest).  Potential sanctions include blocking and prohibiting “all transactions in all property and interests in property of the entity.”

The new law is set to Sunset in 7 years and so will not be codified within the United States Code (USC).  However, the law does rely upon the DTSA definition of trade secret found in 18 U.S.C. 1839:

[T]he term “trade secret” means all forms and types of financial, business, scientific, technical, economic, or engineering information, including patterns, plans, compilations, program devices, formulas, designs, prototypes, methods, techniques, processes, procedures, programs, or codes, whether tangible or intangible, and whether or how stored, compiled, or memorialized physically, electronically, graphically, photographically, or in writing if— (A) the owner thereof has taken reasonable measures to keep such information secret; and (B) the information derives independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable through proper means by, another person who can obtain economic value from the disclosure or use of the information.

Under Federal Law, the theft of trade secrets held by US persons for the purpose of taking information out of the US is also a felony. See, Economic Espionage Act.

But, for the most part the practice of trade secrecy law is radically different than that of patent law.  I’m wondering the extent that patent attorneys are engaging in the transition.

Guest Post by Prof. Burstein: Design patents: Line drawing & Locarno

By Sarah Burstein, Professor of Law at Suffolk University Law School.

Columbia Sportswear North America, Inc. v. Seirus Innovative Accessories, Inc., 21-2299 (submitted but not decided) (oral argument recording available here)

The Federal Circuit heard oral arguments yesterday in the second round of Columbia v. Seirus. (Prior Patently-O coverage of this appeal is available here.) My 2015 article, The Patented Design, was mentioned several times during the argument.

In that article, I argued that a design patent’s scope should be limited to the design as applied to a specific type of product. In making that argument, I acknowledged that this approach could create some line-drawing problems, including the type that have arisen in Columbia v. Seirus. I suggested that, with respect to infringement:

[O]ne solution would be to put the burden of proof on the patent owner to show that the accused device should be considered the same type of product. Courts have been tasked with determining which products are and are not the same “type” of product in the trademark context; there is no obvious reason why they should not be able to do the same in the design patent context.

If, however, the line-drawing problem proves to be intractable, an alternative would be to determine product “types” according to the Locarno Agreement Establishing an International Classification for Industrial Designs. Specifically, “type of product” could be defined to map onto Locarno sub-classes. For example, Locarno Class 10 includes subclasses for “Clocks and Alarm Clocks,” “Watches and Wrist Watches,” and “Other Time-Measuring Instruments.” The Locarno classification system is not perfect for this use but it may provide a second-best solution if judicial common law development proves unworkable.

Sarah Burstein, The Patented Design, 83 Tenn. L. Rev. 161, 219–20 (2015) (footnotes omitted). So my argument was not that design patent scope (and in this case, the scope of comparison prior art) must be limited to the exact, specific type of article named expressly in the verbal portion of the design patent claim.

Instead, I argued that courts should look to whether the accused product (or reference) is the same general type of article.

I also suggested that the product type could be determined with reference to Locarno sub-classes. How might that work in practice?

Looking at the dispute in Columbia v. Seirus, the most relevant class would seem to be Class 5, “Textile piece goods, artificial and natural sheet material.” Here are the relevant class subheadings:

So which subclass(es) would apply here? This case is an example of how the “substantial latitude” that design patent applicants are given in describing the relevant article in their claim language, see MPEP § § 1503.01(I), might sometimes complicate later attempts at classification.

The asserted design patent, U.S. Patent No. D657,093, claims “the ornamental design of a heat reflective material.” The only Class 5 subclass heading that uses the word “material” is 05-06, “Artificial or Natural Sheet Material.” But the patented design seems to be directed more to something like the examples mentioned in subclass 05-05, “Textile Fabric.” (Indeed, if you look closer at the full Locarno Classification, subclass 05-05 specifically includes ID No. 100480, “Insulating fabrics.”)

So which bucket would the D’093 fit in best? Where classification is disputed, the burden of persuasion should be on whichever party wants to prove something is the same type of product.

For infringement, then, the patent owner should have to prove the accused product is the same type as what is claimed. For comparison prior art, the accused infringer should have to prove the reference is the proper type. (This is because the use of the prior art in evaluating infringement is a one-way ratchet; it can only be used to narrow the presumptive scope of a claim, not to enlarge it. See Sarah Burstein, Is Design Patent Examination Too Lax?, 33 Berkeley Tech. L.J. 607, 612 (2018).)

Evidence relevant to this inquiry could include information about any commercial embodiments, including information the patent owner has provided to regulators about their product or market. And if a patent owner has registered their design internationally, the design may already have a Locarno sub-class.

Who should decide? Judges would be well-suited to make these types of determinations. Indeed, these issues are likely to arise at the Markman stage or, as in Columbia v. Seirus, in motions in limine. This is not the kind of credibility or historical-facts determination that we normally leave to juries. Indeed, it’s difficult to imagine a way to effectively instruct juries on this issue without injecting undue confusion into the infringement analysis.

Guest Post by Prof. Contreras: How the ‘Patent Eligibility Restoration Act’ Would Harm American Businesses and Endanger Global Health by Reintroducing ‘Pathogen Patents’

Guest Post by Professor Jorge L. Contreras

The Patent Eligibility Restoration Act should be modified to prevent the reintroduction of patents on naturally-occurring genomic sequences that are isolated and purified in the lab, a change that will enable international pathogen research to continue while interfering little with private incentives to develop new biomedical technologies.

The Patent Eligibility Restoration Act of 2022 (PERA), introduced by Senator Thom Tillis (R-NC) in August 2022, is designed, among other things, to abrogate the Supreme Court’s patent eligibility decisions in Bilski, Mayo, Myriad and Alice. While Congressional action may be useful to clarify the confusing landscape of patent eligibility that has followed from these decisions, particularly in areas such as medical diagnostics, software and business methods, one piece of the eligibility puzzle that the Supreme Court got right, and which should not be changed, is Myriad’s holding that naturally occurring genomic sequences are ineligible for patent protection, even when “isolated and purified.”

In my book, The Genome Defense: Inside the Epic Legal Battle Over Who Owns Your DNA (New York: Algonquin, 2021), I discuss the Myriad case at length, focusing on its implications for human health and access to care.  Like many others, I am concerned that PERA would make newly identified human genetic variants with significant health implications (e.g., this and this) patentable again, potentially removing them from the broad competitive market and placing them in the hands of the first research team that chances to identify them (a task that is, today, largely serendipitous and requires little innovative skill). I have previously discussed these concerns here. In this post, however, I focus on a different and less-discussed issue: the risk that non-human pathogenic genomic sequences (i.e., from viruses and bacteria) will be patented by non-U.S. institutions and used to delay the development of lifesaving diagnostics, vaccines and therapeutics.

When Patents Held Up Pathogen Research

Prior to the Myriad decision, research groups around the world were able to obtain patents on newly identified pathogen genomic sequences, including those of the H5N1 influenza strain and the SARS and MERS coronaviruses. As I discuss in this new article, these patents led to disputes and delays in research on the diseases and effective countermeasures. After Myriad, however, research groups appear to have stopped seeking patents on new pathogenic agents, as shown by the global experience with the Ebola and Zika outbreaks, leading to greater global cooperation and rapid responses by public health agencies and private developers of diagnostics, vaccines and therapeutics.

SARS-CoV-2:  the Benefits of Patent-Free Pathogens

The genomic sequence of SARS-CoV-2 (the virus responsible for COVID-19) was first identified in early January 2020 by a team of researchers in China. On January 5, they uploaded the sequence to the publicly accessible GenBank database. Within days, diagnostic tests for the virus had been developed and a few months later, new vaccines against COVID-19 were being tested. As I have written previously, the unavailability of patents on genomic sequences, and the rapid uploading of the SARS-CoV-2 sequence to public databases, enabled researchers around the world to study the viral genome without fear of patent infringement and without the need to negotiate complex patent licensing agreements and pay royalties to the first researchers to determine its sequence. This open and unencumbered global research environment enabled scientists to identify and trace the spread of multiple pathogenic variants around the world, to understand the biological mechanisms of the virus, and to develop vaccines, diagnostics and therapeutics, all in record time.

PERA and U.S. Competitiveness

Senator Tillis, when introducing PERA, explained that a major goal of the bill is to enhance “the economic and global competitiveness of the United States”. He faults judicial decisions like that in Myriad for “undermining American innovation and allowing foreign adversaries like China to overtake us in key technology innovations.” Likewise, supporters of the draft legislation have enthusiastically proclaimed that it will “rev the US innovation engine once again”, warning that “[e]conomic growth, job creation, global competitiveness, public health and national security are all at risk until Congress repairs the law of patent eligibility that the Supreme Court has distorted.”

Yet, ironically, at least in the case of pathogenic sequences, PERA would work largely to benefit institutions in China and elsewhere, and could have adverse consequences for U.S. businesses and global public health.

Pathogens Usually Emerge, and are Sequenced, Outside the United States

Most serious pathogenic outbreaks result from the transmission of disease agents from animals to humans. These outbreaks originate in regions characterized by extensive animal husbandry, live animal markets, hunting or habitat loss. Within these parameters, the particular locale of a future outbreak is unpredictable. Recent infectious disease outbreaks have been traced, respectively, to China (SARS and H5N1), Saudi Arabia (MERS), Zaire and Congo (Ebola), Uganda and Brazil (Zika).

Likewise, once a pathogenic outbreak has entered human populations, the locations where its variants will emerge is also unpredictable. For example, the major variants of SARS-CoV-2  were first documented in China (original strain), the United Kingdom (alpha), South Africa (beta, omicron), Brazil (gamma), India (delta), Peru (lambda) and Botswana (omicron).

Today, genomic sequencing equipment is widely available at a modest cost. Researchers in 2021 estimated that the cost of sequencing a SARS-CoV-2 genome (only 1/100,000 the size of the human genome) is approximately $120, bringing it well within the reach of researchers in countries such as Gambia, which had, by mid-2021, sequenced more SARS-CoV-2 genomes than Germany.

It is also worth noting that countries, including the United States, that are parties to the World Trade Organization (WTO) Agreement on Trade Related Aspects of Intellectual Property (TRIPS) must give “national treatment” to applicants from all other member states. Thus, researchers from any TRIPS member country may apply for a U.S. patent and will be afforded the same rights as applicants from the United States. Indeed, for the past several years, most U.S. patents have been issued to non-U.S. applicants. In 2021, for example, of approximately 374,000 issued U.S. patents, nearly 200,000 (roughly 53%) were issued to foreign entities. This situation is not unique to the United States and is simply indicative of today’s global technology markets.

The combination of unpredictable sites of pathogenic emergence, inexpensive genome sequencing and national treatment under TRIPS suggests that if U.S. patents become available for pathogenic sequences, the parties most likely to obtain these patents will originate outside of the United States in countries that are likely sites of disease emergence. It is doubtful that allowing pathogen patenting would result in more patents being issued to U.S. applicants. Rather, U.S. and other companies that wished to develop diagnostics, vaccines and other technologies dependent on those sequences would either be excluded from the market or required to pay unpredictable prices for a license to operate under those patents.

Countries That Are Willing to Hold-Up Research

In recent years, certain foreign governments have shown themselves willing to hold-up international disease research and response efforts in order to gain concessions and advantages for themselves under the banner of “access and benefit sharing” (ABS). The most prominent example of this tactic occurred in 2006-07, when the government of Indonesia refused to share samples of the H5N1 influenza virus strain with the World Health Organization until it obtained commitments regarding access to any resulting biomedical products. Similar tactics were adopted by other countries during the MERS, Ebola and Zika outbreaks, as documented here.

If countries are willing to hold-up international research and disease response in order to secure ABS benefits for themselves, then they are also likely to use patents to extract further concessions from the international community. Demands for ABS concessions are not necessarily unjustified in view of past exploitation of local resources by foreign firms in developing countries. Yet even if justified, these barriers to the international response to emergent disease outbreaks can negatively impact global health. Reintroducing pathogen patenting will give countries where diseases emerge yet another tool to hold-up critical international research and development to the detriment of all.

Patents are not Necessary to Incentivize Pathogen Sequencing

One of the principal functions of the patent system is to provide financial incentives for innovators to develop new technologies. Yet, this rationale does not support the issuance of patents claiming pathogen sequences. The identification of new pathogens during emergent disease outbreaks is rarely undertaken by private industry. Rather, this function is usually carried out by public health agencies and academic laboratories, typically in the locale of the outbreak, and which are supported by public funds. Thus, unlike the development of vaccines and therapeutics, the financial incentives offered by patent exclusivity are not necessary to incentivize these early stage research efforts.

There Are Ample Patentable Innovations Relating to Disease Response and Containment Beyond Pathogen Sequences

It is also unnecessary to patent underlying pathogenic sequences in order to protect novel and innovative technologies such as diagnostics, vaccines and therapeutics. A 2012 WIPO study identified more than 50,000 patents and published patent applications across 57 countries that claimed the active ingredients of pneumonia, typhoid and influenza vaccines, most without claiming the underlying pathogen. Even more opportunities for innovation exist with respect to therapeutics, which can adopt a broad range of approaches to combating infection. For example, Regeneron filed more than 100 patent applications around the world on its Ebola drug Inmazeb, though the viral sequence was freely available on GenBank.

The broad availability of patents for innovation around pathogenic disease outbreaks is amply demonstrated by the COVID-19 pandemic. Despite the absence of patents claiming the SARS-CoV-2 sequence or its many variants, the research institutions and private firms that developed COVID-19 diagnostics and vaccines obtained numerous patents on the innovative aspects of their products. For example, one 2020 study found that, with respect to mRNA vaccine technology alone, 56 different entities ranging from large pharmaceutical companies to small and medium-sized entities held a total of 119 different patent families. Perhaps the most convincing evidence that sizeable numbers of patents have issued in this space is the expanding universe of patent litigation among mRNA vaccine manufacturers, now dubbed the “COVID-19 Patent Wars”. All of these examples demonstrate that COVID-19 technology innovations, vaccines in particular, have been amply protected without the need for patents on naturally occurring pathogenic sequences.

But is this Threat Real?

An argument that may be made against the need to limit further pathogen patents is that the ability of patent holders to enforce their patents, especially during global health crises, is limited by law.  For example, in the United States, a patent holder cannot obtain a permanent injunction preventing an infringer from practicing a patented invention unless it demonstrates that the public interest would not be disserved by the entry of the injunction.  Likewise, the International Trade Commission, when assessing the appropriateness of an exclusion order barring the importation of infringing goods into the United States, must take into account “the effect of such exclusion upon the public health and welfare.”  These limitations have greatly reduced (but not entirely eliminated) the number of injunctions and exclusion orders issued with respect to medical and health-related technologies.

These limitations suggest that, at least in the United States, the existence of patents claiming pathogenic sequences might not represent a significant threat to pathogen research or biomedical product development. However, the existence of patents on these basic research tools, no matter what the likelihood of eventual litigation outcomes, can chill research, impose delays and prompt the payment of unwarranted fees. Moreover, even meritless claims are costly to fend off in court and impose some level of risk on defendants, particularly in the U.S. where fee shifting is rare.  Thus, while various litigation doctrines may tend to lessen the threat of pathogen patents in the U.S., that threat is not eliminated entirely and may still represent a significant cost and deterrent to firms engaged in research and development of pathogen-based biomedical products.

Don’t Let PERA Potentially Hold Up Research Efforts

For the reasons outlined above, PERA should be modified to ensure that naturally occurring genomic sequences – even once isolated – remain ineligible subject matter for patent protection. Preventing the reintroduction of pathogen patents will enable international pathogen research to advance rapidly while interfering little with private incentives to develop innovative new biomedical technologies. In contrast, opening the door to pathogen patents arguably will provide opportunities for individual countries where outbreaks emerge to hold up international research efforts for their own benefit, causing delays and barriers to the development of lifesaving diagnostics, vaccines and drugs.

New PatentlyO L.J. Article: What Every Patent and Trademark lawyer Should Understand About the MPEP, TMEP, and Other Guidance

By Jason Rantanen

New Patently-O Law Journal article by  David Boundy, a partner at Potomac Law Group, PLLC.

What Every Patent and Trademark Lawyer Should Understand About the MPEP, TMEP, and Other Guidance: How to Use (and Defend Against) the MPEP to be a Better Advocate, by David Boundy – Boundy.2021.HowToUseGuidance.pdf

Every four years, the PTO issues new guidance documents.  Some of them are legal and either help applicants or give nonbinding advice.  Other guidance documents are beyond the PTO’s authority and create burdens that ought not be shifted onto the public.  Several recent notices from the Patent Office note that several batches are coming.

The administrative law lays out limits on the ways that federal agencies may use guidance documents vis-à-vis rights of the public.  Every patent practitioner should understand those limits—when does the MPEP state binding law, when is it mere aspiration for what an agency would like the law to be or would like you to do, when is it asymmetric (binding against the agency, but not against any member of the public), when is it an offer of a quid pro quo (the agency promises “if you do this, we’ll do that”), and when is it invalid and entirely unenforceable?  When has the PTO broken the law, and what rights does that give you?  Knowing the difference, and following the practical advice outlined below, can prevent you from unintentionally compromising your client’s rights.
