New Administration, Same Patent Reform Bill

by | May 8, 2025 |

A bipartisan group of senators and congressional representatives reintroduced the Patent Eligibility Restoration Act (PERA), which aims to reform the law of patent eligibility under 35 U.S.C. § 101. PERA seeks to address the challenges posed by recent Supreme Court decisions and restore clarity and predictability in the US patent system.

PERA preserves the existing categories of subject matter currently enumerated in § 101 but adds several categories of excluded subject matter. PERA proposes to eliminate all judicial exceptions to patent eligibility, specifying that certain categories, such as mathematical formulas that are not part of an invention, processes that a human could perform, mental processes, unmodified human genes, and unmodified natural material, are not eligible for patents.

A separate bipartisan group of senators and congressional representatives reintroduced the Promoting and Respecting Economically Vital American Innovation Leadership (PREVAIL) Act, which aims to protect and increase the value of US intellectual property rights by making significant reforms to the Patent Trial & Appeal Board.

PREVAIL seeks to limit Board challenges to entities that have been sued or threatened with a patent infringement lawsuit, close the statutory bar joinder loophole to prevent time-barred entities from joining instituted inter partes review (IPR) proceedings, and prevent serial petitions by applying estoppel at the time the challenge is filed instead of when the Board issues its final written decision.

PTO Accelerates Patent Issuance Timeline

by | Apr 24, 2025 |

The US Patent & Trademark Office (PTO) announced that it has shortened the time between the issue notification and the issue date for patents. Historically, the time between these two events averaged about three weeks. Seeking to provide earlier protection for inventions, the PTO intends to reduce that time to about two weeks. The PTO is making the move because publishing electronic grants via the PTO online platform has allowed the PTO to eliminate redundancies and reduce the time between grant notification and the issuance date. The shortened wait time has the added benefit of potentially allowing patent applicants to avoid the Quick Path Information Disclosure Statement (IDS), which attempts to streamline filing an IDS after payment of the issue fee.

Practice Note: Given the accelerated timeline, the PTO recommends that applicants file continuation applications before payment of the issue fee to ensure codependency.

Broadcast Alert! Applying Conventional Machine Learning to New Data Isn’t Patent Eligible

by | Apr 24, 2025 |

The US Court of Appeals for the Federal Circuit affirmed a district court’s ruling that patents applying established machine learning methods to new data are not patent eligible under 35 U.S.C. §101. Recentive Analytics, Inc. v. Fox Corp. et al., Case No. 23-2437 (Fed. Cir. Apr. 18, 2025) (Dyk, Prost, Goldberg, JJ.)

Recentive sued Fox, alleging infringement of four patents designed to tackle long-standing challenges in the entertainment industry – namely, optimizing the scheduling of live events and refining “network maps,” which determine the content aired on specific channels across various geographic markets at set times. These patents aim to streamline broadcast operations and enhance programming efficiency.

The patents at issue can be divided into two categories: network maps and machine learning training. The machine learning training patents focus on generating optimized event schedules by training machine learning models with parameters such as venue availability, ticket prices, performer fees, and other relevant factors. The network map patents describe methods for dynamically generating network maps that assign live events to television stations across different geographic regions. These methods utilize machine learning to optimize television ratings by mapping events to stations and updating the network map in real time based on changes to the schedule or underlying criteria. The patents’ specifications explain that the methods employ “any suitable machine learning technique” using generic computing machines.

Fox moved to dismiss on the grounds that the patents were subject matter ineligible under § 101. Recentive acknowledged that the concept of preparing network maps had existed for a long time. Recentive also recognized that the patents did not claim the machine learning technique. Nonetheless, Recentive argued that its patents claimed eligible subject matter because they involve using machine learning to generate custom algorithms based on training the machine learning model. Recentive characterized its patents as introducing “the application of machine learning models to the unsophisticated, and equally niche, prior art field of generating network maps for broadcasting live events and live event schedules.”

The district court disagreed and granted Fox’s motion. Applying the Alice framework, at step one, the court determined that the asserted claims were “directed to the abstract ideas of producing network maps and event schedules, respectively, using known generic mathematical techniques.” At step two, the court determined that the machine learning limitations were no more than “broad, functionally described, well-known techniques” that claimed “only generic and conventional computing devices.” The court denied Recentive’s request for leave to amend because it determined that any amendment would be futile. Recentive appealed.

For the Federal Circuit, this case presented a question of first impression: whether claims that do no more than apply established methods of machine learning to a new data environment are patent eligible.

Step One

While Recentive claimed that its machine learning approach was uniquely dynamic and capable of uncovering hidden patterns in real time, the Federal Circuit found these features to be merely standard aspects of how machine learning operates. The Court explained that iterative training and model updates are not [...]

A Patent Without a Pulse: Provisional Rights Don’t Outlive the Patent

by | Apr 10, 2025 |

The US Court of Appeals for the Federal Circuit dismissed an appeal from a patent applicant seeking provisional rights on a patent that would issue only after it had already expired, finding that the applicant lacked the necessary exclusionary rights to support a claim for provisional rights. In re: Donald K. Forest, Case No. 23-1178 (Fed. Cir. Apr. 3, 2025) (Taranto, Schall, Chen, JJ.)

Donald K. Forest applied for a patent on December 27, 2016. Forest’s patent application claimed priority through a chain of earlier-filed patent applications dating back to March 27, 1995. If Forest’s patent application matured into a patent, it would have expired 20 years after the 1995 priority date (i.e., prior to the 2016 filing date). The patent examiner nevertheless examined and rejected the proposed claims. The Patent Trial & Appeal Board partially affirmed the examiner’s rejection of certain claims on grounds of obviousness and double patenting. Forest appealed.

The Patent & Trademark Office raised a threshold issue that since Forest’s application could only result in an expired patent, he lacked a personal stake in the appeal sufficient to establish jurisdiction. Forest countered that he could still acquire “provisional rights” under 35 U.S.C. § 154(d) – a limited right to royalties for certain pre-issuance activities – despite the expiration of any issued patent as it issued.

The Federal Circuit dismissed the appeal, explaining that since Forest could not be granted a patent until after the patent’s expiration date, he would never receive any exclusionary rights. The Court clarified that provisional rights only arise once a patent issues and crucially do not extend beyond the statutory patent term. Because Forest sought the issuance of a patent that would confer no enforceable rights – either exclusionary or provisional – the Court dismissed the appeal for lack of jurisdiction.

The Federal Circuit’s primary conclusion was predicated on the principle that provisional rights are only available when a patent issues with enforceable exclusionary rights, meaning the patent must issue before its expiration date. The Court emphasized that provisional rights under § 154(d) are expressly provided “in addition to other rights provided by” the patent statute. Because this statutory language indicates that provisional rights are not standalone, the Court determined that provisional rights depend on the existence of a valid, enforceable patent.

According to the Federal Circuit, the entire purpose of provisional rights is to provide temporary relief to the patentee during the gap between publication of a patent application and issuance of a patent. However, such rights only arise if the issued patent provides enforceable rights. The Court reasoned that provisional rights are meant to encourage early publication and protect patentees from pre-issuance infringement, but only as a precursor to full patent protection.

The Court rejected Forest’s interpretation of § 154(d), explaining it would create an anomalous situation where provisional rights could survive without any corresponding enforceable rights, allowing a patentee to collect royalties on a patent that could never be asserted in infringement litigation.

Practice Note: Patent rights, whether provisional [...]

What’s the (Re)issue? Patent Term Extensions for Reissue Patents

by | Mar 27, 2025 |

Addressing the calculation of patent term extensions (PTEs) under the Hatch-Waxman Act, the US Court of Appeals for the Federal Circuit affirmed a district court decision that under the act the issue date of the original patent should be used to calculate the extension, not the reissue date. Merck Sharp & Dohme B.V. v. Aurobindo Pharma USA, Inc., Case No. 23-2254 (Fed. Cir. Mar. 13, 2025) (Dyk, Mayer, Reyna, JJ.)

Merck owns a patent that is directed to a class of 6-mercapto-cyclodextrin derivatives. Four months after the patent issued, Merck applied to the US Food & Drug Administration (FDA) for approval of sugammadex, which it intended to market as Bridion®. During FDA’s review of Merck’s new drug application (NDA), Merck filed a reissue application that included narrower claims. The reissue application issued and included all the original claims and 12 additional claims. FDA regulatory review continued throughout the examination of the reissue application and extended almost two years beyond the date the patent reissued. In all, the FDA regulatory review lasted nearly 12 years.

The Hatch-Waxman Act provides owners of patents related to pharmaceutical products a process to extend the term of their patent rights to compensate for time lost during regulatory review of their NDAs. The act contains a clause providing that “the term of a patent . . . shall be extended by the time equal to the regulatory review period . . . occur[ring] after the date the patent is issued.” Having been unable to market the invention covered by the patent for almost 12 years because of FDA’s regulatory review, Merck filed a PTE application for its reissue patent seeking a five-year extension (the maximum allowed under the act) based on the patent’s original issue date. The US Patent & Trademark Office (PTO) agreed and granted the five-year extension.

Between the reissue date and the PTO’s grant of the five-year extension, Aurobindo and other generic manufacturers had filed abbreviated new drug applications (ANDAs) seeking to market generic versions of Bridion®. Merck sued for infringement. At trial, Aurobindo argued that the PTO improperly calculated the PTE by using the original issue date instead of the reissue date because only 686 days of FDA’s regulatory review occurred after the reissue date, as opposed to the almost 12 years which had passed since the initial issue date. The district court disagreed, finding that Aurobindo’s proposed construction “would undermine the purpose of the Hatch-Waxman Act.” Aurobindo appealed.

Aurobindo argued that the act’s reference to “the patent” referred to the reissue patent because that is the patent for which the patentee was seeking term extension. Merck argued that the act’s text, read in light of other patent statutes and the history of patent reissue, required the opposite conclusion (i.e., a PTE based on the original issue date).

The Federal Circuit agreed with Merck, explaining that while the language of the PTE text may be ambiguous, that ambiguity may be resolved by considering the PTE text in light of the history of [...]

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.

Promises, Promises: Covenant Not to Sue for Patent Infringement Includes Downstream Users

by | Oct 31, 2024 |

The US Court of Appeals for the Tenth Circuit affirmed that a district court did not err in applying ordinary rules of contract construction to a covenant not to sue and properly found that under the patent exhaustion doctrine, the covenant encompassed downstream users. Fuel Automation Station, LLC v. Energera Inc., Case Nos. 23-1123; -1358 (10th Cir. Oct. 21, 2024) (Carson, Rossman, Federico, JJ.)

Fuel Automation Station (FAS) and Energera compete in the manufacture of automated fuel delivery equipment and related services. Energera holds patents related to its fuel delivery equipment. In 2016 and 2018, Energera sued FAS, alleging that it infringed two of its patents. The parties resolved the suits with a single settlement agreement in 2019. The agreement described the scope of the patent rights at issue and provided mutual covenants not to sue.

Less than a year later, FAS contracted with a Canadian corporation to operate its fuel automation equipment. Energera sued the Canadian corporation for infringement of one of its patents. FAS intervened, then separately sued Energera seeking a declaration that the covenant not to sue authorized FAS to sell or lease its own equipment and, therefore, the patent exhaustion doctrine prohibited Energera from suing downstream users, such as the Canadian corporation. FAS also brought two breach of contract claims asserting that Energera violated the settlement agreement and its included covenant since it was prohibited from suing the Canadian corporation for downstream use or from suing or “otherwise engag[ing]” FAS in legal proceedings.

FAS moved for summary judgment on its declaratory judgment count, which the district court granted. However, the court denied both parties’ later motions for summary judgment on the issue of whether the settlement agreement covered the asserted patent, finding that an ambiguity in the agreement created genuine issues of material fact. A jury subsequently found that the agreement did cover the asserted patent and that Energera breached the covenant. Energera appealed.

After first determining that the district court’s summary judgment ruling was an appealable legal ruling on the issue of the scope of the covenant, the Tenth Circuit found that the district court correctly interpreted the covenant to include downstream users. In the covenant, Energera promised “not to sue [FAS] or otherwise engage [FAS] in any domestic or foreign legal or administrative proceeding” related to the Patent Rights. Citing dictionary definitions of “engage” in its analysis, the Tenth Circuit found that the term “otherwise engage” reasonably could show the parties’ intent to prohibit Energera from suing FAS’s downstream users. The Court then invoked the patent exhaustion doctrine, which it called “the brooding omnipresence in the sky of patent law.” The Court explained that if a patent holder promises not to sue an entity for patent infringement when the entity sells or leases an item, “the doctrine recognizes an inherent promise not to sue downstream users of those items.” Otherwise, the Court pointed out, no reasonable customer would want to buy or lease a patented item from an authorized seller.

As to whether the [...]

What a Croc! False Claim That Product Feature Is Patented Can Give Rise to Lanham Act Violation

by | Oct 17, 2024 |

The US Court of Appeals for the Federal Circuit reversed and remanded a grant of summary judgment on a false advertising claim, concluding that a cause of action under Section 43(a) of the Lanham Act can arise when a party falsely claims to hold a patent on a product feature and advertises that feature in a misleading way. Crocs, Inc. v. Effervescent, Inc., Case No. 2022-2160 (Fed. Cir. Oct. 3, 2024) (Reyna, Cunningham, JJ.; Albright, District J., sitting by designation).

Crocs, the well-known maker of molded foam footwear, sued several competitor shoe distributors for patent infringement in 2006. The case was stayed pending an action before the International Trade Commission but resumed in 2012 when Croc added competitor U.S.A. Dawgs as a defendant to the district court litigation. The case was stayed twice more, from 2012 to 2016 and 2018 to 2020. In between those stays, in May 2016, Dawgs filed a counterclaim against Crocs and 18 of its current and former officers and directors, alleging false advertising violations of Section 43(a) of the Lanham Act. 15 U.S.C. § 1125(a). The individual defendants were later dismissed from the action.

Dawgs claimed that Crocs deceived consumers and damaged its competitors by falsely describing its molded footwear material, which it calls “Croslite,” as “patented,” “proprietary,” and “exclusive.” Dawgs alleged that it was damaged by Crocs’ false advertisements and commercial misrepresentations because Crocs suggested that its competitors’ footwear material was inferior. Croslite is in fact not patented, as Crocs conceded.

Crocs argued in its motion for summary judgment that Dawgs failed as a matter of law to state a cause of action under Section 43(a) because the alleged advertising statements were directed to a false designation of authorship of the shoe products and not to their nature, characteristics, or qualities, as Section 43(a)(1)(B) requires. The district court agreed. Applying the Supreme Court’s 2003 decision in Dastar Corp. v. Twentieth Century Fox Film Corp. and the Federal Circuit’s 2009 decision in Baden Sports, Inc. v. Molten USA, Inc., the district court granted summary judgment to Crocs. It reasoned that falsely claiming to have “patented” something is similar to a false claim of authorship or inventorship, not to the types of false advertising prohibited by the Lanham Act. Dawgs appealed.

Dawgs argued that the district court’s application of Dastar and Baden to the circumstances of its case was inapposite, and the Federal Circuit agreed. In Dastar, the petitioner copied a television series in the public domain, made minor changes, and sold it as a video set, passing it off as its own. The Supreme Court held that a false claim of authorship does not give rise to a cause of action under the Lanham Act. Similarly, in Baden, the Federal Circuit found that a basketball manufacturer’s false suggestion that it was the author of the “innovative” “dual-cushion technology” in its basketballs did not give rise to a false advertising claim under the Lanham Act.

In this case, however, the Federal Circuit reasoned that Croc’s false [...]

Stay Focused: New Point of View of Patent Eligibility

by | Sep 19, 2024 |

The US Court of Appeals for the Federal Circuit reversed and remanded a district court’s decision that the asserted claims were patent ineligible under 35 U.S.C. § 101, finding that the district court improperly characterized the claims at an “impermissibly high level of generality.” Contour IP Holding LLC v. GoPro, Inc., Case Nos. 22-1654; -1691 (Fed. Cir. Sept. 9, 2024) (Prost, Schall, Reyna, JJ.)

Contour owns two patents related to portable point-of-view (POV) video cameras. The patents disclose a hands-free POV action sports video camera configured for remote image acquisition control and viewing. The key embodiment describes “dual recording” where the camera generates video recordings “in two formats, high quality and low quality.” The lower quality file is streamed to a remote device for real-time adjustment of bandwidth limiting video parameters while the higher quality version of the recording is saved for later viewing.

In 2015, Contour sued GoPro, alleging that several GoPro products infringed the asserted patents. In 2021, Contour again sued GoPro, alleging that several newer products infringed the same patents. In 2021, after the district court granted partial summary judgment that GoPro’s accused products infringed the claims in the first lawsuit, GoPro filed a motion in the second lawsuit challenging the claims as patent ineligible under 35 U.S.C. § 101. GoPro relied heavily on the Federal Circuit’s 2021 decision in Yu v. Apple in its arguments for ineligibility. The district court initially denied the motion, but when GoPro raised the issue again at summary judgment, the district court agreed with GoPro and found the claims patent ineligible under § 101.

At step one of the Alice eligibility test the district court found that the claims were directed to the abstract idea of creating and transmitting video at two different resolutions and adjusting the video’s settings remotely. At Alice step two, the district court found that the claim recited only functional, result-oriented language without indicating that physical components behaved in any way other than their basic generic tasks. Contour appealed.

The Federal Circuit reversed, finding that when read as a whole, the claim was directed to a specific means that improved a relevant technology and required “specific, technological means – parallel data stream recording with the low-quality recording wirelessly transferred to a remote device – that in turn provide a technological improvement to the real time viewing capabilities of a POV camera’s recordings on a remote device.”

The Federal Circuit found that the district court’s decision was based on an “impermissibly high level of generality” that led to its incorrect conclusion that the claims were related to an abstract idea. The Court also disagreed with GoPro’s argument that Yu was dispositive in this case, explaining that in Yu, there was no dispute that the “idea and practice of using multiple pictures to enhance each other has been known by photographers for over a century.” The Court determined that Contour’s claim enabled a POV camera, with its dual recording capability, to operate differently than it otherwise [...]

The Conversation Continues: Some Post-Patent-Termination Royalties Are Acceptable

by | Sep 12, 2024 |

For the second time in less than two weeks, a circuit court decided an appeal hinging on the Brulotte rule, which holds that patent royalties are impermissible when based on payments for the use of expired patents. Like the US Court of Appeals for the Ninth Circuit, the Fourth Circuit upheld a royalty agreement that purported to require payments after patent expiration. Ares Trading S.A. v. Dyax Corp., Case No. 23-1487 (4th Cir. Aug. 14, 2024) (Krauser, Porter, Chung, JJ.)

Dyax is a biotechnology company engaged in “phage display” research – a laboratory process used to identify antibody fragments for use in developing medications. Dyax holds multiple patents related to phage display, including licenses to patents owned by Cambridge Antibody Technology (CAT). Dyax and Ares entered a licensing agreement. Dyax’s main obligation was to use its phage display technology to identify antibody fragments and then provide those fragments to Ares so that Ares could incorporate them into commercial medications, including one called Bavencio. In exchange, Ares agreed to pay Dyax at various research milestones and pay royalties for identified products, including Bavencio. Although Bavencio was first sold in 2017, the last CAT patent expired in 2018.

After learning of the Brulotte rule, Ares tried to renegotiate its contract obligations. When renegotiation attempts failed, Ares sued Dyax, seeking multiple related declaratory judgments revolving around its argument that its royalty obligations to Dyax were unenforceable under Brulotte. Dyax countersued on six claims, including for declaratory judgment that Brulotte did not apply. The district court found the royalty obligation enforceable and not in violation of Brulotte. Ares appealed.

Ares asked the Fourth Circuit to reconsider the applicability of the Brulotte rule and to relatedly find that Dyax had breached the covenant of good faith and fair dealing. The Fourth Circuit first examined its own jurisdiction in the context of the Federal Circuit’s exclusive jurisdiction over patent appeals. Of the 10 total claims and counterclaims, nine arose under Massachusetts contract law. According to the Fourth Circuit, these were not “substantial” patent law claims and thus regional circuit appellate jurisdiction was appropriate.

The Fourth Circuit next turned to the Brulotte prohibition on post-termination royalties and found no violation because “Ares’ royalty obligation is not calculated based on activity requiring post-expiration use of inventions” covered by Dyax or CAT patents. The Court emphasized the policies underpinning the federal patent regime and the Brulotte rule, particularly the importance of inventions entering the public space once a patent expires to allow continued innovation and general use of the once-patented invention. The Court also explained its understanding of the nuances of Brulotte, as informed by the Supreme Court’s 2015 decision in Kimble v. Marvel. For instance, a court’s inquiry must focus on post-expiration use, so where “royalties are not calculated based on activity requiring post-expiration use, they do not hinder post-expiration use ‘on their face’ and Brulotte is not implicated.” In the present case, this was a key delineation because the Fourth Circuit found that Ares’ [...]
