USPTO Director to decide AIA petitions

by | Oct 23, 2025 | ,

The United States Patent and Trademark Office (USPTO) issued a memorandum on October 17, 2025, titled “Director Institution of AIA Trial Proceedings,” providing updated guidance to the Patent Trial & Appeal Board regarding the standards and procedures for instituting trial proceedings under the America Invents Act (AIA), including inter partes review (IPR) and post-grant review (PGR).

Since the AIA’s enactment in 2012, the Board’s trial proceedings have become a central mechanism for challenging the validity of issued patents. The institution phase, in which the Board decides whether to proceed with a trial, has been shaped by a series of precedential decisions and evolving USPTO policies, particularly regarding discretionary denials under 35 U.S.C. §§ 314(a) and 325(d).

The October 17, 2025, memorandum states that to “improve efficiency, consistency, and adherence to the statutory requirements for institution of trial, effective October 20, 2025, the Director will determine whether to institute trial for [IPR and PGR] proceedings.” If the Director determines that review is appropriate based on discretionary, merits-based, or other considerations, the USPTO will issue a summary notice granting institution for at least one challenged claim. If the Director determines review is not appropriate, the USPTO will issue a summary notice denying institution. For cases involving novel or complex issues, the Director may issue a detailed decision or refer the matter to one or more Board judges. A three-member Board panel will conduct all instituted reviews. The memorandum also notes that the USPTO has issued more than 580 prior decisions under interim processes that offer guidance on handling of discretionary factors.

Oh brother: Draft settlement agreements carefully

by | Sep 18, 2025 | ,

The US Court of Appeals for the Eighth Circuit affirmed a district court judgment, finding that the plaintiff failed to sufficiently prove damages for its copyright claim, the jury instructions accurately applied the sophisticated consumer exception to initial-interest confusion, and the district court properly submitted ambiguous contract language to the jury for interpretation. Hoffmann Brothers Heating and Air Conditioning, Inc. v. Hoffmann Air Conditioning & Heating LLC, Case No. 24-1289 (8th Cir. Sept. 8, 2025) (Graza, Stras, Kobes, JJ.)

Brothers Tom and Robert Hoffmann were partners in Hoffmann Brothers. After Robert bought out Tom, they entered into a settlement agreement that included a four-year restriction barring Tom from using the name “Hoffmann” in connection with an HVAC business. After four years, Tom began using “Hoffmann Air Conditioning & Heating, LLC” (Hoffmann AC). Hoffmann AC’s advertising agency later mistakenly used pictures of Hoffmann Brothers. Hoffmann Brothers sued for trademark and copyright infringement. Hoffmann AC prevailed on some issues at summary judgment, and the jury reached a mixed verdict on the remaining claims. Both parties were denied attorneys’ fees, and Hoffmann Brothers appealed.

On appeal, the Eighth Circuit affirmed that Hoffmann Brothers did not sufficiently prove damages for its copyright claim based on Hoffmann AC’s use of its photographs. Because the photographs were unregistered works, Hoffmann Brothers was required to prove actual damages and/or additional profits of the infringer attributable to the infringement. Hoffmann Brothers’ only evidence of actual damages was Hoffmann AC’s monthly fee paid to its marketing agency. The Court found that using the monthly fee was too speculative because it did not reflect the benefit to Hoffmann AC or the harm to Hoffmann Brothers. For evidence of additional profits, Hoffmann Brothers’ expert report failed to link the use of the photographs to Hoffmann AC’s gross revenue. The Court explained that the Hoffmann Brothers could have linked additional profits attributable to the use of the photographs by, for example, demonstrating that:

  • Hoffmann AC gained customers because of the ads.
  • The photographs actually influenced purchasing decisions.
  • There was spike in monthly revenue that coincided with use of the photographs.

Regarding Hoffmann Brothers’ trademark claim, the jury found that the names were not so similar as to cause confusion. Hoffmann Brothers appealed, arguing that the district court erred in its jury instructions. The Eighth Circuit rejected the argument, finding the instructions fair and legally adequate. The instruction was directed to the issue of initial-interest confusion (a concept not adopted by Missouri courts), which occurs when consumer confusion arises at the outset, even if no sale ultimately results. The Court explained that under Eighth Circuit precedent, a sophisticated consumer exception applies to this theory, meaning that consumers who exercise a high degree of care are less likely to be initially confused. Here, the district court instructed the jury to consider initial-interest confusion only if it found that Hoffmann Brothers’ customers were not sophisticated. While the Eighth Circuit acknowledged some hesitation about the assumption that sophisticated consumers are never susceptible to initial-interest [...]

Claims barred by laches: Prosecution delay doesn’t pay, nor does skipping evidence of concrete injury

by | Sep 11, 2025 |

The US Court of Appeals for the Federal Circuit affirmed a district court’s judgment for the US Patent & Trademark Office (PTO) on application of prosecution laches in an action under 35 USC § 145. The Federal Circuit also agreed that the district court lacked Article III jurisdiction over certain claims because the plaintiff failed to provide evidence of concrete injury when challenged after initial pleadings. Hyatt v. Stewart, Case Nos. 2018-2390; -2391; -2392; 2019-1049; -1038; -1039; -1070; 2024-1992; -1993; -1994; -1995 (Fed. Cir. Aug. 29, 2025) (Reyna, Wallach, Hughes, JJ.) (precedential).

Gilbert Hyatt filed four GATT bubble patent applications, all of which had claims rejected by the examiner. Hyatt appealed those rejections to the Patent Trial & Appeal Board, which affirmed various rejections of others. Following the Board decisions, Hyatt filed four separate actions in district court under 35 U.S.C. § 145, challenging the PTO rejections. In response, the PTO asserted prosecution laches as an affirmative defense and, in the alternative, invalidity, based on anticipation and lack of written description.

The district court initially ruled in Hyatt’s favor, finding that the PTO’s affirmative defenses failed with respect to the claims for which the Board affirmed the examiner’s rejection. The district court concluded that it lacked Article III jurisdiction over the remaining claims (those for which the Board reversed the examiner) because there was no final agency action as to those claims.

The PTO appealed, arguing that prosecution laches barred all of the claims or, in the alternative, that the claims were invalid. Hyatt cross-appealed, contending that prosecution laches did not apply in § 145 actions or that the district court abused its discretion in applying laches in these specific § 145 actions.

In an earlier appeal, Hyatt I, the Federal Circuit vacated the district court’s rulings on prosecution laches, holding that the district court applied the wrong standard for prosecution laches and had the burden of proving that Hyatt engaged in unreasonable and unexplained delay in prosecuting his applications and that the delay was prejudicial. The panel remanded the case held the issue of Article III jurisdiction in abeyance. On remand, the district court reversed course and found in favor of the PTO on prosecution laches, concluding that Hyatt had unreasonably delayed prosecution in a manner that prejudiced the agency.

Hyatt appealed. The Federal Circuit consolidated the appeals with the earlier stayed jurisdictional issues. The Federal Circuit affirmed the district court’s application of prosecution laches, finding no clear error in its determination that Hyatt’s conduct met the standard for delay and prejudice. The Federal Circuit also agreed that the district court lacked Article III jurisdiction over claims that had not been finally rejected by the PTO, reinforcing that § 145 actions may only proceed where there is a final agency determination resulting in a justiciable controversy.

On the issue of prosecution laches, the Federal Circuit explained that it had already considered and rejected Hyatt’s argument that prosecution laches is unavailable in a § 145 action in Hyatt I, and [...]

Kissing cousins? SUNKIST and KIST deemed confusingly similar

by | Jul 31, 2025 |

The US Court of Appeals for the Federal Circuit reversed a Trademark Trial & Appeal Board decision, concluding that there was a likelihood of confusion between the marks KIST and SUNKIST when used in connection with soft drinks. Sunkist Growers, Inc. v. Intrastate Distributors, Inc., Case No. 24-1212 (Fed. Cir. July 23, 2025) (Prost, Taranto, Stark, JJ.)

For at least 90 years, Sunkist has offered soft drinks under the SUNKIST trademark both directly to consumers and through its licenses. Intrastate Distributors Inc. (IDI) purchased the KIST brand and proceeded to use the KIST mark for soft drink and sparkling water products. The KIST mark was active for about a decade before being cancelled in 2013. In 2019, IDI filed intent-to-use trademark applications for the KIST mark both in standard characters and in a stylized character form for “[s]oft drinks, namely, sodas and sparkling water; concentrates and syrups for making soft drinks.” Sunkist opposed the registration, arguing the KIST mark was likely to cause confusion with the SUNKIST mark.

Focusing its analysis on the SUNKIST standard character mark, the Board determined that all DuPont factors other than similarity of the marks favored likelihood of confusion. The Board found that the marks were not sufficiently similar because they conveyed different commercial impressions. According to the Board, while SUNKIST referenced the sun, the KIST mark referenced a kiss, relying on the image of lips that appear next to the KIST mark. The Board therefore found no likelihood of confusion between IDI’s marks and the registered SUNKIST marks. Sunkist appealed.

The Federal Circuit began by emphasizing that the KIST mark was not a design mark and the image of lips did not always appear beside the mark. The Court relied on the following image in its opinion, noting that “[n]one of the bottles include a lips image or reference a kiss” and instead “emphasize flavors.”

kist bottles

The Federal Circuit noted that the record contains no evidence concerning the degree of consumer exposure to the mark with the image of lips versus without lips. The Court found that the Board relied too heavily on the KIST mark’s appearance alongside an image of lips, and ultimately determined that substantial evidence did not support the finding that the mark referenced a kiss. The Court noted that while some of the SUNKIST marks contained a sun, many were standard character marks that did not include a sun. The Court thus concluded that substantial evidence did not support a finding that the similarity of the marks favored no likelihood of confusion.

Since the Board had previously found that the remaining DuPont factors favored likelihood of confusion and the Federal Circuit determined that the similarity of the marks also favored likelihood of confusion, the only remaining consideration was actual confusion. Although Sunkist had not proven instances of actual confusion, the Court noted that its precedents had never required actual confusion, primarily because [...]

Game over: Prior interference doesn’t preclude IPR proceeding

by | Jul 31, 2025 |

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board unpatentability determination during an inter partes review (IPR) proceeding, concluding that the Board’s decision to not apply interference estoppel fell within the general rule of unreviewability. IGT v. Zynga Inc., Case No. 23-2262 (Fed. Cir. July 22, 2025) (Prost, Reyna, Taranto, JJ.)

IGT owns an expired patent that addresses the need for gaming machines, such as slot machines and video poker machines, to securely communicate over a public network. The patent was issued in January 2007 from an application filed in April 2002 and published in August 2002. Zynga filed a patent application on August 21, 2003, that included claims copied from IGT’s published application.

In March 2010, the US Patent & Trademark Office (PTO) Board of Patent Appeals & Interferences (predecessor of the Patent Trial & Appeal Board, which Congress created in 2011) declared an interference proceeding between Zynga’s application and IGT’s patent. During the interference proceeding, Zynga argued IGT’s patent was obvious over three pieces of prior art. IGT argued that Zynga lacked standing because the claims in Zynga’s application were unpatentable for a lack of written description. The Board granted IGT’s motion for judgment on the “threshold issue” that Zynga’s application lacked adequate written description support, terminated the interference with a judgment against Zynga, and dismissed the motion that the claims were unpatentable as moot.

In April 2021, IGT sued Zynga alleging infringement of six patents, including the patent that was subject to the interference proceeding. Zynga filed an IPR petition for that patent, asserting obviousness based on new prior art. In its preliminary response, IGT argued that the Board should deny institution based on interference estoppel under 37 C.F.R. § 41.127(a)(1) because Zynga could have raised the newly asserted art in the interference proceeding. The Board rejected IGT’s interference estoppel arguments because:

  • The interference was terminated based on the “threshold issue” of lack of written description and therefore the Board did not analyze or decide any issues of unpatentability.
  • It would be unfair to estop Zynga, and to the extent that estoppel applied, the Board waived its application under 37 C.F.R. § 42.5(b).

IGT requested rehearing and precedential opinion panel review, arguing that interference estoppel barred institution. The PTO Director affirmed the Board’s decision, stating that interference estoppel under § 41.127 did not apply because IPR proceedings are governed by 37 C.F.R. pt. 42, which does not incorporate Part 41 or its estoppel provisions. The PTO Director also noted that the Board’s termination was based on a threshold issue. The Board proceeded with the review and ultimately concluded that all the challenged claims were unpatentable as obvious. IGT appealed.

IGT argued that the Board and PTO Director erred in ruling that interference estoppel did not bar the petition and challenged the Board’s holding that the claims would have been obvious over the newly asserted prior art.

The Federal Circuit concluded that the interference estoppel determination fell within the [...]

Royal Play Penalty: No Standing in the End (Zone)

by | Apr 24, 2025 |

The US Court of Appeals for the Federal Circuit dismissed an appeal from the Trademark Trial & Appeal Board, finding that the appellant lacked standing because it failed to allege any actual and particularized injury. Michael J. Messier v. New Orleans Louisiana Saints, LLC, Case No. 24-2271 (Fed. Cir. Apr. 14, 2025) (per curiam) (Moore, C.J.; Prost, Stark, JJ.) (nonprecedential)

Michael J. Messier claimed that he is a direct descendent of the kings of France, and that he and his family own intellectual property rights to the Fleur-de-Lis mark used by the NFL’s New Orleans Saints. Messier filed a petition with the Board for cancellation of the Saints’ Fleur-de-Lis mark. Messier’s petition contained no claim that he or his family currently use any fleur-de-lis marks in commerce or any other avenues for revenue, such as licensing. The Board dismissed the petition.

The Board held that pursuant to Sections 13 and 14 of the Lanham Act, 15 U.S.C. §§ 1063 and 1064, to maintain a cancellation action, Messier had to “allege a commercial interest in the registered mark or a reasonable belief in damage from the mark’s continued registration.” Messier’s original and amended petitions failed to do so. The Board noted that Messier did not own or conduct “any business under the mark, and thus he cannot allege entitlement.” Messier appealed.

The Federal Circuit determined that Messier lacked standing to bring the appeal. The Court explained that to demonstrate Article III standing for his appeal, Messier had to demonstrate actual or imminent injury that was concrete and particularized, a causal connection between the alleged conduct and the injury, and potential redressability by a favorable decision. Messier failed to meet his burden, primarily because he failed to demonstrate injury by the Saints’ use of the Fleur-de-Lis mark that went beyond “a general grievance or abstract harm.” Messier did not allege that he used a fleur-de-lis design in commerce whatsoever and thus failed to demonstrate any injury.

PTO Reverts to Prior Post-Grant Guidelines for Cases Involving Parallel District Court Litigation

by | Mar 13, 2025 |

On February 28, 2025, the acting director of the US Patent & Trademark Office (PTO) announced that the agency will revert to previous guidelines for discretionary denials of petitions for post-grant proceedings where there is ongoing district court litigation.

This announcement rescinds the PTO’s June 21, 2022, memorandum entitled “Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation.” The memorandum stated that the Patent Trial & Appeal Board “will not deny institution of an IPR or PGR under Fintiv (i) when a petition presents compelling evidence of unpatentability; (ii) when a request for denial under Fintiv is based on a parallel ITC proceeding; or (iii) where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition.” The memorandum effectively limited the discretion granted in Fintiv, which outlined six factors for the Board to consider when making decisions on post-grant proceedings involving parallel district court litigation.

Now that the 2022 memorandum has been rescinded, parties to post-grant proceedings should refer to Board precedent, including Fintiv and Sotera Wireless v. Masimo, for guidance when there are parallel district court proceedings. In accordance with prior guidelines, the PTO’s objective is to achieve greater consistency in its decision-making processes, especially in situations where patent validity is contested both in the courts and before the Board. The PTO emphasized that any portions of future Board decisions that rely on the 2022 memorandum will not be binding or persuasive.

Practice Note: Because of this action, the Board will now enjoy greater discretion when ruling on post-grant petitions, which may result in an increase of discretionary denials.

Case Closed: OpenAI Prevails on Secondary Meaning

by | Dec 5, 2024 |

The US Court of Appeals for the Ninth Circuit affirmed a district court’s grant of a preliminary injunction (PI) in a trademark action under the Lanham Act, stating that the district court’s ruling was not clearly erroneous based on its finding that the plaintiff had likely acquired secondary meaning in the mark. OpenAI, Inc. v. Open Artificial Intelligence, Inc., Guy Ravine, Case No. 24-1963 (9th Cir. Nov. 13, 2024) (Thomas, Owens, Collins, JJ.) (per curiam) (Collins, J., dissenting) (nonprecedential).

OpenAI is the founder of ChatGPT and other artificial intelligence tools. OpenAI has used the OPENAI (no space) mark extensively in association with its goods, services, website, social media, and marketing. OpenAI first attempted to register the mark with the US Patent & Trademark Office (PTO) in 2016, but the PTO rejected the mark as being merely descriptive and potentially confusing with Guy Ravine’s prior-filed application for the mark OPEN AI (with a space). Ravine claimed to have used the mark as early as 2015, which would have predated OpenAI’s use of its mark. However, the PTO also rejected Ravine’s application for registration on the Principal Register under a similar rationale, and the OPEN AI mark was only accepted for registration on the Supplemental Register in 2017. Neither mark is registered on the Principal Register.

OpenAI filed a trademark action under the Lanham Act against Ravine’s company, Open Artificial Intelligence, and sought a PI, which the district court granted after finding that OpenAI had established that it had acquired distinctiveness in the mark. Ravine appealed the denial of Open Artificial Intelligence’s motion under Fed. R. Civ. P. 59(e) and 60(b) to amend or vacate that injunction.

A PI is granted when a plaintiff establishes that:

  • It is likely to succeed on the merits.
  • It is likely to suffer irreparable harm.
  • The balance of equities tips in its favor.
  • An injunction is in the public interest.

The Ninth Circuit applies a sliding scale approach, where a stronger showing of one factor could offset a weaker showing of another factor. To succeed on a trademark infringement claim, a plaintiff must show that it has a protectible ownership interest in the mark and that the defendant’s use of the mark is likely to cause consumer confusion.

To evaluate the claims, the district court looked at each of the parties’ history and use of the disputed marks. The district court noted that OpenAI had used its mark in connection with its most widely used product, ChatGPT, resulting in the mark becoming a household name. The district court recognized that OpenAI’s trademark was one of the most recognized in artificial intelligence (AI) history. The district court noted that OpenAI’s website was one of the most visited websites, with almost 100 million monthly active users. In contrast, the district court found that Ravine had not established that he had used the mark in commerce prior to OpenAI’s use and even took issue with Ravine’s representations regarding his use of the mark. The district court granted [...]

Senate Judiciary Subcommittee Advances Two Patent Reform Bills

by | Dec 5, 2024 |

This post has been updated since its original publication date.

On November 15, 2024, the US Senate Judiciary Subcommittee on Intellectual Property advanced the Inventor Diversity for Economic Advancement (IDEA) Act, one of three significant bills it considered this year to reform the patent system. On November 21, 2024, that same subcommittee advanced the Promoting and Respecting Economically Vital American Innovation Leadership (PREVAIL) Act. No action has been taken by the subcommittee yet regarding the Patent Eligibility Restoration Act (PERA). It is unlikely any of these bills will become law before the new Congress begins on January 3, 2025.

The IDEA Act, sponsored by Senator Mazie Hirono (D-HI) and garnering bipartisan support, would require the US Patent & Trademark Office to seek demographic data from patent inventors residing in the United States on a voluntary basis. The bill also includes safeguards to protect the confidentiality of the collected information and ensure it is not used as part of the examination process, with a report to be submitted to Congress biannually.

By the time of the November 21 action, the subcommittee sent the PREVAIL Act, sponsored by Senators Christopher Coons (D-DE) and Thom Tillis (R-NC), to the full US Senate. In the words of Coons, the PREVAIL Act is intended to make proceedings before the Patent Trial & Appeal Board “cheaper, swifter, more efficient alternatives to federal district court.” The PREVAIL Act would enact substantial changes to post-grant and inter partes review proceedings at the Board, including by introducing a standing requirement, aligning standards more closely with district court standards, and strengthening estoppel provisions to prevent re-litigation of validity issues.

The substance of PERA and the PREVAIL Act have been reported on previously here and here, respectively. PERA would revise the standards related to patent eligibility under 35 U.S.C. § 101, which have been broadly criticized as providing insufficient predictability and certainty. PERA would overturn Supreme Court precedent by establishing specific categories of exceptions to broad patent eligibility for inventions or discoveries.

At the November 15 hearing, Coons and Tillis explained that they continue to receive feedback on PERA, which has been unsuccessfully introduced in previous years. Coons and Tillis both telegraphed optimism that PERA was moving toward being voted out of the subcommittee. After the November 21 hearing, both sponsors indicated that they hoped PERA would be voted on soon.

How Close Are They? PTO Looking for “Significant Relationship” Between Sequential IPR Petitioners

by | May 9, 2024 |

Addressing the issue of whether to discretionally deny a petition for inter partes review (IPR) under the General Plastics factors when there is no “significant relationship” between the petitioners, the Director of the US Patent & Trademark Office (PTO) vacated the Patent Trial & Appeal Board’s decision denying institution. Videndum Prod. Sol., Inc. v. Rotolight Ltd., IPR2023-01218 (PTO-Ofc. of Dir., Apr. 19, 2024) (Vidal, PTO Dir.)

Videndum filed a petition requesting IPR challenging claims of a patent owned by Rotolight. In its Patent Owner’s Response, Rotolight argued to the Board that it should exercise its discretion to deny institution under 35 U.S.C. § 314(a), citing the Board’s 2017 precedential decision in General Plastic. Prior to Videndum’s petition, the Board instituted review of the same patent at the request of another party. However, one month prior to oral argument in that proceeding, the parties to that IPR proceeding jointly moved to terminate the proceeding on the basis of a settlement. The Board granted the parties’ joint petition.

In the present case, a split Board denied Videndum’s petition for institution, reasoning that Videndum’s petition was a “follow on” of the prior proceeding, and citied General Plastic even while conceding that the “Petitioner’s reliance on [the] earlier-filed petition …, even ‘as a menu and roadmap’” is not sufficient “to create ‘a significant relationship’ that favors denial under the first General Plastic factor.” The dissent agreed on that point but argued that the “General Plastic factors as whole weigh against exercising discretion to deny institution.”

Videndum requested Director review of the Board’s denial of institution based on an abuse of discretion argument. The Director granted review.

The Director found error with the Board’s application of the General Plastic factors in situations where the second-in-time petition is not by the same party that filed the first petition or by a party having a “significant relationship” with the first filer.

The General Plastic factors generally deal with how the Board should analyze whether to institute a subsequent petition on the same patent. Factor one explicitly asks whether the two petitioners are the same. However, the application of the General Plastic factors “is not limited solely to instances when multiple petitions are filed by the same petitioner.” But, when the factors are applied to different petitioners, they have been applied to petitioners who have a “significant relationship” with each other.

Here, both the parties and the Board agreed that there is not a “significant relationship” between the two petitioners. As the Director noted, the PTO has never extended the General Plastic factors “to any cases in which the first and second petitioners do not have a significant relationship.” The Director found the Board’s unprecedented extension of the General Plastics factors to be “improper[],” vacated the Board’s decision, and remanded the case with an instruction to the Board majority to “address the merits of the Petition.”

Practice Note: Patent owners fighting institution of an IPR by a subsequent petitioner should allege facts emphasizing the relationship between the two [...]
