US Court of Appeals

Not “Use It or Lose It”: Even if Unexercised, Director’s Authority over Institution Decisions Remains

by Christopher M. Bruno | Aug 25, 2022 | Patents

The US Court of Appeals for the Federal Circuit denied mandamus relief, finding that a party is not entitled to petition the director for review of a Patent Trial & Appeal Board (Board) decision denying institution of an inter partes review (IPR) or post-grant review (PGR) proceeding. This ruling reflects the Court’s ongoing consideration of the Supreme Court’s decision in United States v. Arthrex, Inc., which held that Board judges cannot constitutionally render final decisions in IPRs without US Patent & Trademark Office (PTO) Director oversight. Click here for our discussion of the case on remand, for which the Federal Circuit just denied en banc rehearing. In re Palo Alto Networks, Inc., Case No. 22-145 (Fed. Cir. Aug. 16, 2022) (Dyk, Chen, JJ.) (Reyna, J., concurring).

After being sued by Centripetal Systems for patent infringement, Palo Alto Networks filed petitions for IPR and PGR of some of the asserted patents. The Board denied institution, and Palo Alto Networks filed requests for Director rehearing. Although the PTO acknowledged receipt of the request, it informed Palo Alto Networks that the Director was not considering requests for rehearing of institution decisions “at this time.” Thereafter, Palo Alto Networks sought a writ of mandamus from the Federal Circuit. Between the request for mandamus and the Court’s decision, the PTO issued guidance explaining that although the PTO was not considering requests for rehearing, “the Director has always retained and continues to retain the authority to review such decisions sua sponte after issuance (at the Director’s discretion),” and indeed, exercised its authority to initiate sua sponte review since.

The Federal Circuit rejected Palo Alto Networks’ claim that the Director’s refusal to consider petitions for rehearing of institution decisions amounted to an abdication of authority prohibited by the Appointments Clause. Even assuming that institution decisions were “final decisions on how to exercise executive power” implicating the Appointments Clause, the Court found that the Director maintains statutory and regulatory authority to review institution decisions (unlike in Arthrex), and that the Board renders such decisions only based on the Director’s delegation of authority (also unlike Arthrex). Accordingly, the structural authority maintained by the Director is sufficient, even if such authority goes unexercised, according to the Court.

Writing separately, Judge Reyna agreed that no Appointments Clause violation had occurred but on different grounds. Although Judge Reyna noted that a categorical rejection of requests for rehearing by the Director might raise constitutional concerns, he concluded that mandamus was inappropriate for several reasons. First, the Director’s caveat that she refused to accept requests “at this time” did not constitute a categorical refusal but rather an exercise of discretion. Second, the Director’s invocation of her sua sponte authority to review belied a lack of exercise of discretion. The Director did in fact exercise sua sponte authority to consider Palo Alto Networks’ request, even though briefing in the Federal Circuit was pending, and thus a writ of mandamus was inappropriate.

Not a Well-Crafted Housing: Product-by-Process Claim Element Isn’t Limiting

by Thomas DaMario | Aug 25, 2022 | Patents

The US Court of Appeals for the Federal Circuit affirmed a ruling that certain claims reciting a “housing . . . being cast in one piece” should be construed as a product-by-process claim element and affirmed the subsequent finding of invalidity of all challenged claims. Kamstrup A/S v. Axioma Metering UAB, Case No. 21-1923 (Aug. 12, 2022) (Reyna, Mayer, Cunningham, JJ.)

Kamstrup owns a patent directed to an ultrasonic flow meter housing in the form of a monolithic polymer structure that is cast in one piece. The patent specification explains that the invention can be fabricated with fewer steps compared to existing meters, since only a single step is used to form the monolithic polymer structure. Axioma petitioned for inter partes review of all claims of the patent, and the Patent Trial & Appeal Board (Board) found each claim unpatentable as either obvious or anticipated.

The Board construed the claim term “being cast in one piece” to be a product-by-process claim element. Kamstrup did not present any evidence showing that this claim element provided structural or functional differences distinguishing the housing itself from the prior art, and therefore the Board determined that the housing element was not entitled to patentable weight. The Board subsequently invalidated the independent claim and various dependent claims based on a prior art meter having a housing. The Board also found the remaining dependent claims to be invalid based on two additional references, which the Board determined were sufficiently analogous to flow meter technology to merit consideration in its obviousness analysis.

On appeal, Kamstrup challenged the Board’s product-by-process construction. The Federal Circuit explained that product-by-process claiming is designed to enable an applicant to claim an otherwise patentable product that resists definition other than by the process by which it is made. Where a product-by-process claim element is implicated, structural and functional differences distinguishing the claimed product from the prior art must be shown in order for that claim element to be relevant (limiting) to the anticipation or obviousness inquiry. If no structural or functional differences are shown, the element is given no patentable weight. Turning to the claim element at issue, the Court found that the plain meaning of the term “housing . . . being cast in one piece” implicated a product-by-process interpretation since it described the structure “being” cast in a particular way. The Court also affirmed the Board’s finding of invalidity because Kamstrup failed to identify any disclosure in the specification, prosecution history or extrinsic evidence of any structural or functional differences between the housing element as claimed and the prior art.

Kamstrup also argued that the two secondary prior art references were not analogous prior art because they fell within the field of “medical devices for thermodilution,” and therefore they should not be included in an obviousness analysis. The Federal Circuit disagreed, finding that the references were directed to “sensing or measuring fluid flow and fluid flow characteristics such as temperature,” which is related to “flow meters that include different types of sensors.”

Prior Art Citation to Inventors’ Report Not “By Another” for § 102(e)

by Paul Devinsky | Aug 25, 2022 | America Invents Act, Patents

The US Court of Appeals for the Federal Circuit found that a prior art patent’s summarization of a report authored by the inventors of a patent challenged under inter partes review (IPR) did not constitute a disclosure “by another” under pre-America Invents Act § 102(e). LSI Corp. v. Regents of Univ. of Minnesota, Case No. 21-2057 (Fed. Cir. Aug. 11, 2022) (Dyk, Reyna, Hughes, JJ.)

The Regents of the University of Minnesota (UMN) sued LSI Corporation and Avago Technologies (collectively, LSI) for infringement of a patent related to methods for reducing errors in binary data sequences. LSI petitioned for IPR, challenging several claims of the asserted patent and arguing that they were anticipated by two prior art references, Okada and Tsang. Tsang made reference to a “Seagate Annual Report” that was published by the inventors of the asserted patent, and which was later embodied in the patent’s application.

The Patent Trial & Appeal Board (Board) found that one of the challenged claims was anticipated by Okada. The Board also found that LSI had not shown that the other challenged claims were rendered unpatentable by either Okada or Tsang and further rejected an invalidity (anticipation) theory first raised by LSI during oral arguments as untimely (while noting that the argument failed even if timely raised). The Board determined that the Tsang reference was not “by another” under § 102(e) because LSI’s petition relied solely on material that was originally disclosed in the inventor’s Seagate Annual Report. LSI appealed the Board’s determinations relating to invalidity based on Okada or Tsang.

The Federal Circuit noted that LSI did not challenge the Board’s untimeliness determination and rejected LSI’s argument that it did not need to because the Board nevertheless reached a merits decision on the argument. The Court cited to its 2016 decision in Intelligent Bio-Systems v. Illumina Cambridge, which held that “the Board’s rejection of arguments on the ground that they were newly raised in a reply brief was not an abuse of discretion even though the Board went on to address the merits.”

Turning to the § 102(e) issue, the Federal Circuit first explained that an invention is anticipated under § 102(e) if the invention is described in a patent application filed “by another,” but a patent owner may overcome such anticipation by establishing that the relevant prior art disclosure describes the owner’s invention. Describing the history of the Tsang reference and the patent under review, the Court explained that the inventors originally submitted a Seagate Annual Report to Seagate, a UMN collaborator. Tsang, a Seagate employee, received the report and quickly filed a patent application for an improvement on the methods described in the report. This application listed only Tsang as inventor and made direct reference to the Seagate Annual Report.

The Federal Circuit then addressed whether LSI’s IPR petition relied on Tsang’s improvement to the inventors’ report or simply on Tsang’s summary of the inventors’ report. The Court explained that while LSI’s petition relied on both Tsang’s summary of the [...]

Rebuttal Presumption of Irreparable Harm Still Alive When Assessing Trademark Preliminary Injunctions

by Amol Parikh | Aug 25, 2022 | Trademarks

In one of the first decisions to construe the Trademark Modernization Act of 2020 (TMA), the US Court of Appeals for the Third Circuit found that a district court properly applied the TMA’s rebuttal presumption of irreparable harm when it denied a trademark owner’s motion for a preliminary injunction. Nichino America, Inc. v. Valent U.S.A., LLC, Case No. 21-1850 (3rd Cir. Aug. 12, 2022) (Bibas, Matey, Phipps, JJ.)

Nichino and Valent sell pesticides for farming. Since 2004, Nichino has offered a trademarked product known as CENTAUR. Valent trademarked a competing product called SENSTAR in 2019, giving it a logo resembling CENTAUR’s colors, fonts and arrow artwork. Both pesticides are used in the same geographic areas against many of the same insects, and both are sold to farmers through distributors. SENSTAR is a liquid and uses a unique combination of two active chemicals. It costs $425 per gallon and ships in cases containing four one-gallon containers. CENTAUR is manufactured as a solid and sold by the pallet, with each pallet containing 622 pounds of pesticide packed into bags and cases. CENTAUR costs $24 per pound.

Nichino sued Valent for trademark infringement and sought a preliminary injunction against SENSTAR’s launch, arguing that Valent’s use of the SENSTAR mark would create confusion among consumers. The district court found that Nichino narrowly demonstrated that its infringement claim would likely succeed but explained that “there is not an abundance of evidence of likelihood of confusion” between the products. As part of its injunction analysis, the district court applied the TMA to presume Nichino would suffer irreparable harm without an injunction. However, the court noted that the presumption was rebuttable. The court credited Valent’s evidence of a sophisticated consumer class that makes careful purchases and noted the lack of any evidence of actual consumer confusion. The court also found that Nichino failed to proffer any affirmative evidence that it would suffer irreparable harm. Accordingly, the district court found that the presumption of irreparable harm was rebutted, and therefore denied the injunction request. Nichino appealed.

Nichino argued that the TMA precluded the district court from finding no irreparable harm. The Third Circuit, however, found that the district court “admirably navigated” the TMA’s rebuttable presumption by finding that Valent rebutted the presumption and Nichino did not independently show irreparable harm. The Court explained that the three-step process for applying the TMA’s rebuttable presumption requires the following:

The court must assess the plaintiff’s evidence only as it relates to a likelihood of success on the merits.
If the plaintiff’s evidence establishes likely trademark infringement, the TMA is triggered, and the burden of production shifts to the defendant to introduce evidence sufficient for a reasonable factfinder to conclude that the consumer confusion is unlikely to cause irreparable harm.
If a defendant successfully rebuts the TMA’s presumption by making this slight evidentiary showing, the presumption has no further effect.

The Third Circuit found that the district court correctly followed this three-step analysis in finding that Valent rebutted the TMA’s [...]

Publisher’s Fair Use Defense Dries Up

by Cecilia Choy, Ph.D. | Aug 18, 2022 | Copyrights

The US Court of Appeals for the Ninth Circuit overturned a district court’s summary judgment, rejecting an accused publisher’s argument that their use of copyrighted photos embedded in articles was fair use under the Copyright Act. McGucken v. Pub Ocean Ltd., Case No. 21-55854 (9th Cir. Aug. 3, 2022) (Ikuta, Nguyen, Owens, JJ.)

Elliot McGucken captured and edited photographs of an ephemeral lake that formed on the desert floor in Death Valley. He posted his photos to Instagram and licensed them to several websites that ran articles about the lake. Pub Ocean posted an article about the lake with some digression on loosely related topics. It used 12 of McGucken’s photos, among others, without seeking or receiving a license. McGucken filed suit for copyright infringement. The district court sua sponte granted summary judgment for Pub Ocean, concluding that it was entitled to a fair use defense. McGucken appealed.

The Ninth Circuit reversed after applying the four-factor test in determining whether fair use applies:

The purpose and character of the use
The nature of the copyrighted work
The amount and substantiality of the portion used in relation to the copyrighted work as a whole
The effect of the use upon the potential market for or value of the copyrighted work.

Factor 1: The Purpose and Character of the Use

The Ninth Circuit explained that the question under the first factor is whether the infringing work is transformative and whether it is commercial. Higher transformation in new works means the other factors, including commercialism, are less significant. For-profit news articles are generally considered commercial uses. The Court explained that a work conveying factual information does not transform a copyrighted work when it uses a “clear, visual recording” of the infringing work’s subject.

The Ninth Circuit found that Pub Ocean’s article used the photos for the exact purpose for which they were taken—to depict the lake. The Court disagreed that the article was transformative when Pub Ocean merely “recontextualiz[ed] or repackage[ed] [ ] one work into another.” The Court also disagreed with Pub Ocean’s argument that the fair use defense was strengthened by its purpose of news reporting (one example of fair use listed in 17 U.S.C. § 107). The Court explained that the category of news reporting alone is not sufficient to sustain a per se finding of fair use. The Court also noted that Pub Ocean’s minor cropping and arrangement of photos in the article’s text, even if considered marginal transformation, was too weak to favor fair use.

Factor 2: The Nature of the Copyrighted Work

Under the second factor, the question is the extent to which the copyrighted work is creative and whether it is unpublished. The Ninth Circuit found that McGucken’s photos were creative because they were the product of many technical and artistic decisions. The Court also explained that the publication of the photos on Instagram and in articles failed to weigh in favor of fair use. Citing Dr. Seuss, the Court explained that “while [...]

Veil Piercing Under Lanham Act Requires Specific Showing of Liability

by Sarah J. Fischer | Aug 18, 2022 | Trademarks

The US Court of Appeals for the Eleventh Circuit reversed a district court decision granting summary judgment of liability under the Langham Act, finding that the plaintiffs failed to apply the correct standards for piercing the corporate veil and individual liability in a false advertising and false endorsement dispute. Edmondson et al. v. Velvet Lifestyles, LLC, Case No. 20-11315 (11th Cir. Aug. 4, 2022) (Jordan, Pryor, Marcus, JJ.)

Miami Velvet operated as a swingers’ nightclub in Miami, Florida. Miami Velvet was owned, operated and managed by Velvet Lifestyles, LLC. Joy Dorfman was the president, manager and a salaried employee of Velvet Lifestyles. My Three Yorkies, LLC, was the managing member of Velvet Lifestyles, and Dorfman was, in turn, the managing member of Yorkies. She was also the president of Yorkies and received the management fees that Velvet Lifestyles paid Yorkies. Approximately 30 individuals sued Velvet Lifestyles, My Three Yorkies and Dorfman for false advertising and false endorsement under the Lanham Act. The individuals alleged that Velvet Lifestyles, My Three Yorkies and Dorfman used the individuals’ images in advertisements without their consent, without any compensation and in such a way that implied they were affiliated with and endorsed Miami Velvet.

The district court granted the plaintiffs’ motion for summary judgment, finding that Velvet Lifestyles, My Three Yorkies and Dorfman’s use of the plaintiffs’ images constituted false advertising and false endorsement. The plaintiffs’ motion treated all three defendants as effectively a single entity, and the district court made no finding that either My Three Yorkies or Dorfman had any direct involvement in the advertising. The district court did not apply the individual liability standard to Dorfman and instead treated all three defendants as a single entity as the plaintiffs’ motion had done. A jury awarded damages at trial. After post-trial motion practice, My Three Yorkies and Dorfman appealed.

The plaintiffs argued on appeal that My Three Yorkies and Dorfman had not properly preserved these issues for review on appeal. The Eleventh Circuit rejected the plaintiff’s argument, finding that because the plaintiffs did not properly plead the standards for piercing the corporate veil and individual liability, My Three Yorkies and Dorfman were not obligated to raise or respond to those issues and, therefore, any procedural failures on their part were inconsequential.

Turning to the merits, the Eleventh Circuit reversed the finding of liability on summary judgment. The Court explained that in order for My Three Yorkies to be liable for the actions of Velvet Lifestyles, the plaintiffs had to show that My Three Yorkies was directly involved in the violation of the Lanham Act. The Court found that the plaintiffs failed to show that My Three Yorkies took any action regarding the management of the club or the advertisement in question, and that therefore the plaintiffs had failed to establish that the corporate veil should be pierced. The Court further explained that in order for Dorfman to be liable as an individual, the plaintiffs had to show that she actively participated as the [...]

Single T-Shirt Sale Can’t Clothe Bare-Bones Personal Jurisdiction Claim

by Nitya Anand | Aug 18, 2022 | Trademarks

The US Court of Appeals for the Eighth Circuit affirmed a district court’s dismissal of a trademark infringement suit for lack of personal jurisdiction, finding that the trademark owner failed to allege that the alleged infringer could reasonably anticipate being hauled into court in Missouri. Brothers and Sisters in Christ, LLC v. Zazzle, Inc., Case No. 21-1917 (8th Cir. Aug. 2, 2022) (Smith, Benton, Kelly, JJ.)

Brothers and Sisters in Christ (BASIC) is a Missouri-based clothing company that owns the trademark “love happens.” Zazzle is a California-based online retailer. BASIC sued Zazzle in a Missouri district court for trademark infringement, alleging that Zazzle used its nationally available website to advertise and sell goods in Missouri. BASIC further alleged that in 2019, Zazzle sold and shipped a t-shirt bearing a purportedly infringing “love happens” logo to at least one Missouri resident. The district court granted Zazzle’s motion to dismiss for lack of personal jurisdiction under Fed. R. Civ. P. 12(b)(2). BASIC appealed.

Reviewing the issue de novo, the Eighth Circuit affirmed the dismissal. The Court explained that because the Lanham Act does not authorize nationwide personal jurisdiction, the Court was required to apply Missouri’s long-arm statute and the federal due process clause. Given that Missouri’s long-arm statute authorizes personal jurisdiction over defendants who engage in, among other things, the transaction of any business or the commission of a tortious act within the state, the Court’s inquiry focused on whether exercising personal jurisdiction over Zazzle comported with the due process clause. Because BASIC did not allege that Zazzle was subject to general personal jurisdiction in Missouri (i.e., BASIC did not allege that Zazzle was “essentially at home” in the forum state), the question instead turned on whether BASIC had sufficiently pled facts to support a claim of specific personal jurisdiction.

The Eighth Circuit explained that specific personal jurisdiction existed over Zazzle for the purposes of BASIC’s trademark infringement claims if Zazzle had certain minimum contacts with the forum state and BASIC’s claims arose out of or related to those contacts. For specific jurisdiction to apply, the underlying controversy must be connected to the defendant’s activities in the forum state; unconnected activities directed to the forum state, no matter how numerous or systematic, cannot convey specific personal jurisdiction. The Court used a five-factor test previously set forth in Whaley v. Esebag to conduct its analysis: “(1) the nature and quality of [defendant’s] contacts with the forum state; (2) the quantity of such contacts; (3) the relation of the cause of action to the contacts; (4) the interest of the forum state in providing a forum for its residents; and (5) convenience of the parties.”

The Eighth Circuit found that the behavior alleged by BASIC (Zazzle’s operation of a national website that sells and ships goods to Missouri combined with a single specific instance of an allegedly infringing t-shirt being sold and shipped to a Missouri consumer) was insufficient to support a specific jurisdiction claim. Zazzle’s website availability and sales unrelated to the use [...]

Recapture Rule Applies to Subject Matter Surrendered to Overcome § 101 Rejection

by Paul Devinsky | Aug 18, 2022 | Patents

Affirming a Patent Trial & Appeal Board (Board) decision, the US Court of Appeals for the Federal Circuit held, for the first time, that the rule prohibiting recapture of subject matter surrendered during prosecution applies to subject matter surrendered to overcome a § 101 patent eligibility rejection. In re McDonald, Case No. 21-1697 (Fed. Cir. Aug. 10, 2022) (Newman, Stoll, Cunningham, JJ.)

During prosecution of a parent patent application relating to displaying search results, the inventor, John McDonald, added a “processor” limitation to certain claims to overcome a § 101 rejection. McDonald subsequently filed a continuation application, which was eventually issued. McDonald then filed a reissue application seeking to broaden the claims of the continuation patent by striking all of the originally added “processor” claim language. With the reissue application, he included a declaration that the processor language was unnecessary to the patentability and operability of the relevant claims. The examiner rejected the claims as obvious, and McDonald appealed. On appeal, the Board affirmed the obviousness rejection and also rejected the reissue claims as being based on a defective declaration lacking a correctable error. The Board found that McDonald was impermissibly attempting to recapture surrendered subject matter. McDonald appealed.

Exercising de novo review, the Federal Circuit first recounted more than a century of caselaw relating to patent reissue and recapture. The Court explained that a patent may be reissued if the inventor erroneously claimed less than they had a right to claim in the original patent, but that the recapture rule bars a patentee from regaining that which was surrendered during prosecution. The Court then turned to its three-step recapture analysis in which it considers the following:

Whether, and in what aspect, the reissue claims are broader than the patent claims
If broader, whether those broader aspects of the reissue claim relate to the surrendered subject matter
If they do, whether the surrendered subject matter has crept into the reissue claim.

Applying this test, the Court concluded that McDonald sought to broaden his claims and that the surrendered subject matter crept into those broadened claims. The Court also held that McDonald did not meet the reissue statute’s “error” requirement, finding that his actions were deliberate as opposed to inadvertent or by mistake.

The Federal Circuit then addressed McDonald’s arguments that the recapture rule does not apply to subject matter surrendered to overcome a § 101 rejection. The Court conceded that its previous decisions centered on prior art rejections under § 102 and § 103 but found that the public’s reliance interest on a patent’s public record must also apply to subject matter surrendered under § 101. The Court also reiterated that it “reviews a patent family’s entire prosecution history when applying both the rule against recapture and prosecution history estoppel.” The Court thus affirmed the Board’s decision barring McDonald from reclaiming subject matter previously surrendered during prosecution.

Too Little Too Late: No Tenable Misappropriation Claim Based on 11-Year-Old Prototype

by Tessa Kroll | Aug 11, 2022 | Trade Secrets

In a dispute between an employer and a former employee, the US Court of Appeals for the Seventh Circuit affirmed a district court’s grant of summary judgment against an employer asserting trade secret misappropriation and breach of implied-in-fact contract claims relating to an 11-year-old prototype developed by a former employee. The Court also affirmed the district court’s finding of litigation misconduct by the former employer but vacated the lower court’s award of attorneys’ fees, remanding the case for a more detailed justification for the considerable award. REXA, Inc. v. Chester, Case Nos. 20-2953; -3213; -2033 (7th Cir. July 28, 2022) (Wood, Hamilton, Brennan, JJ.)

Mark Chester is a former employee of Koso America, a manufacturer of hydraulic actuators. Chester participated in a 2002 project at Koso that sought to develop a new flow matching valve for Koso’s actuators. While the project team failed to design a new flow matching valve, they did manage to develop an experimental prototype of an actuator with solenoid valves. Koso abandoned the new design because of the improbability of commercial success, and the prototype was disassembled. Chester—who had never signed a confidentiality or employment agreement with Koso—resigned from Koso in 2003 and later joined MEA Inc. in 2012. In 2013, 11 years after developing the Koso prototype, Chester helped MEA design a new actuator with solenoid valves and an improved motor. MEA filed a patent application in 2017 claiming the actuator, and the US Patent & Trademark Office issued a notice of allowance in 2018 based on the improved motor limitations.

REXA, a successor company to Koso, sued Chester and MEA for misappropriation under the Illinois Trade Secrets Act (ITSA) and for breach of an implied-in-fact contract. REXA alleged that MEA and Chester misappropriated the 2002 designs by filing the 2017 patent application and by incorporating the 2002 designs into MEA’s Hawk brand actuator, and that Chester breached an implied-in-fact obligation to assign any patent rights associated with the 2017 application to REXA. Chester and MEA accused REXA of improper conduct during discovery after REXA appended a confidentiality agreement that Chester had never received to Chester’s 2002 bonus letter and used the manipulated document during Chester’s deposition. The parties filed cross motions for summary judgment. The district court ruled for Chester and MEA and awarded them almost $2.4 million in attorneys’ fees for REXA’s litigation misconduct. REXA appealed.

Misappropriation of Trade Secrets

The Seventh Circuit first considered the trade secret misappropriation claim, specifically whether REXA had identified a trade secret with enough specificity. The ITSA requires that a plaintiff “present a specific element, or combination of elements, that is unknown to the trade and was allegedly misappropriated.” Applying this standard, the Court found that REXA had not identified any protectable trade secrets because it had broadly asserted that the “2002 designs” qualified as trade secrets without explicitly identifying an element that was not well known in the industry.

The Seventh Circuit further concluded that even if REXA had identified a specific and protectable trade secret, [...]

Rage against the Machine: Inventors Must Be Human

by Amol Parikh | Aug 11, 2022 | Patents

The US Court of Appeals for the Federal Circuit found that an artificial intelligence (AI) software system cannot be listed as an inventor on a patent application because the Patent Act requires an “inventor” to be a natural person. Thaler v. Vidal, Case No. 21-2347 (Fed. Cir. Aug. 5, 2022) (Moore, Taranto, Stark, JJ.)

Stephen Thaler develops and runs AI systems that generate patentable inventions, including a system that he calls his “Device for the Autonomous Bootstrapping of Unified Science” (DABUS). In 2019, Thaler sought patent protection for two of DABUS’s putative inventions by filing patent applications with the US Patent & Trademark Office (PTO). Thaler listed DABUS as the sole inventor on both applications. The PTO found that the patent applications lacked valid inventorship and sent a Notice of Missing Parts requesting that Thaler identify a valid inventor. Thaler petitioned the director to vacate the notices. The PTO denied the petitions, explaining that a machine does not qualify as an inventor and that inventors on patent applications must be natural persons. Thaler then pursued judicial review in the district court. The district court agreed with the PTO, concluding that an “inventor” under the Patent Act must be an “individual,” and that the plain meaning of “individual” is a natural person. Thaler appealed.

The sole issue on appeal was whether an AI software system can be an “inventor” under the Patent Act. The Federal Circuit started with the statutory language of the Patent Act, finding that it expressly provides that inventors are “individuals.” The Court noted that while the Patent Act does not define “individual,” the Supreme Court has explained that the term “individual” refers to a human being unless there is some indication that Congress intended a different reading. The Federal Circuit also found that this result was consistent with its own precedent, which found that neither corporations nor sovereigns can be inventors; instead only natural persons can be inventors.

The Federal Circuit rejected Thaler’s policy argument that inventions generated by AI should be patentable to encourage innovation and public disclosure. The Court found that these policy arguments were speculative, lacked any basis in the text of the Patent Act, and were contrary to the unambiguous text of the Patent Act. The Court also rejected Thaler’s reliance on the fact that South Africa has granted a patent with DABUS as an inventor, explaining that the South African Patent Office was not interpreting the US Patent Act. The Court concluded that since Congress has determined that only a natural person can be an inventor, AI cannot be an inventor.

Practice Note: The Federal Circuit’s decision comes on the heels of a decision from the US Copyright Office Review Board finding that a work must be created by a human being to obtain a copyright. The Federal Circuit also noted that it was not confronted with the question of whether inventions made by human beings with the assistance of AI are eligible for patent protection.
