As artificial intelligence (AI) systems become increasingly sophisticated and play a greater role in our society, questions surrounding patentability and inventorship have come to the forefront of intellectual property discourse. This is particularly so in the wake of Thaler v. Vidal, 43 F. 4th 1207, 1213 (Fed. Cir. 2022), cert denied, 143 S. Ct. 1783 (2023), in which the Federal Circuit held that “only a natural person can be an inventor, so AI cannot be.” The U.S. Patent and Trademark Office (USPTO) recently issued guidance aimed at addressing these concerns.

It was an average week all around with 31 new patent filings at the Patent Trial and Appeal Board (PTAB) – all inter partes reviews (IPRs) – and 67 new filings in district court. The bulk of this week’s new PTAB filings (a total of 19) were petitions challenging patents owned and asserted by Entropic Communications LLC [associated with SoftBank Group Corp.] (discussed further below). Other notable filings include petitions challenging patents held by Softex [associated with SoftBank Group Corp.], Dental Imaging Technologies [associated with Envista Holdings Corporation], Resonant Systems [d/b/a RevelHMI], Immersion Corp, and Dsm IP Assets BV [associated with DSM-Firmenich AG].

The most striking (and embarrassing) mistake of law in modern patent law history occurred in the case of eBay Inc. v. MercExchange, 347 U.S. 388 (2006). This mistake led to an alarmingly incorrect outcome and a monumental disruption of U.S. innovation policy…. The traditional and longstanding remedy for trespass on a patent property right is a permanent injunction. By making removal of an established infringer/trespasser optional in eBay, the Supreme Court vastly undercut and devalued every patent’s exclusive right. This erroneous outcome is a cataclysmic policy error, but that policy miscarriage is not itself the embarrassing error of law.

The U.S. Patent and Trademark Office (USPTO) issued a Notice of Proposed Rulemaking (NPRM) today that would allow practitioners who are not registered with the USPTO patent bar to act as lead counsel in proceedings before the Patent Trial and Appeal Board (PTAB). The Office has decided to propose that practitioners must still be represented by a registered practitioner, but to allow parties to “designate a non-registered practitioner as lead counsel and the registered practitioner as back-up counsel.”

The Patent Trial and Appeal Board (PTAB) remains a popular and busy venue for post-grant review of patents. These proceedings are known for being faster, and by statute, they allow for less discovery than district court patent cases. PTAB litigants therefore may not think about potential third-party subpoenas, which can take significant time and effort to obtain. It is possible, however, to obtain a subpoena in a PTAB case. In certain circumstances, a PTAB subpoena can be a useful tool to bolster your case at the PTAB, but there are specific procedures that must be followed to properly issue and enforce such a subpoena. Precise compliance with these procedures is necessary to obtain the discovery sought.

On February 5, 2024, the U.S. Court of Appeals for the Federal Circuit (CAFC) held its en banc oral argument to reconsider the obviousness test for design patents. Overall, the many judges’ questions indicated a hesitancy to change the current law, as they expressed concern with positions advanced by the patent challenger. Listening to the argument, it became instantly clear that the designer’s voice was missing from the arguments of both parties. The judges had deeply probing and important questions that need the input of a design professional. As an experienced design professional, I penned this article to highlight the designer’s voice by providing answers to several critical questions posed by the court during oral argument.

On February 16, the U.S. Court of Appeals for the Federal Circuit issued a pair of precedential rulings in Promptu Systems Corp. v. Comcast Cable Communications, LLC, vacating a final judgment of infringement after reversing part of the district court’s claim construction rulings. The entire U.S. patent community, however, should take notice of the Federal Circuit’s sua sponte order informing future litigants that evading briefing limits by incorporating much larger documents by reference will likely result in sanctions.

In an ideal world, issued patents would not contain errors. In reality, patent drafting is tedious and time-consuming work and perfection is not an attainable goal. The patent industry seems to be steadily getting better, though. In a recent study, we uncovered an 11.24% decrease in errors per patent over the past four years. We observed this decrease by reviewing every patent issued by the U.S. Patent and Trademark Office (USPTO) since 2020 – nearly 1.4 million patents.

It was an average week for patent filings at the Patent Trial and Appeal Board (PTAB) and an above-average week in district courts, with 72 district court complaints filed and 18 new PTAB petitions—one petition for Post Grant Review (PGR), and 17 for Inter Partes Review (IPR). At the PTAB, a number of challenges were filed, including two IPRs by Tesla challenging patents owned by Iqar Inc, four IPRs by Dish challenging patents owned by Entropic Communications LLC (associated with Fortress), two IPRs by Microsoft challenging patents owned by Interdigital Patent Holdings Inc (associated with InterDigital Inc.), and two IPRs by Juniper Networks challenging patents owned by Monarch Networking Solutions LLC (associated with Acacia Research Corporation).

The U.S. Court of Appeals for the Federal Circuit (CAFC) today held that certain claims of a patent for a system to protect against identity theft and fraud were invalid for indefiniteness. Judge Schall dissented-in-part, explaining that he would not have found the claims indefinite based on the intrinsic evidence. U.S. Patent No. 9,361,658 is owned by Mantissa Corporation and is titled “System and Method for Enhanced Protection and Control Over the Use of Identity.” Mantissa sued First Financial Corporation and First Financial Bank, N.A. in the U.S. District Court for the Northern District of Illinois, alleging infringement of certain claims. The parties mainly disputed two terms during claim construction: (1) “transaction partner” and (2) “OFF.” The district court relied on First Financial’s expert testimony to conclude that “transaction partner” was indefinite, after finding that the expert used was a person of ordinary skill in the art (POSA).

Is your company paying the United States Patent and Trademark Office (USPTO) maintenance fees for expired patents? The USPTO requires payment of maintenance fees to keep a granted patent in force due at 3.5 years, 7.5 years, and 11.5 years after the date of grant of a patent. For 2023, these fees amount to $2,000, $3,760, and $7,700, respectively. You may be unknowingly paying maintenance fees for expired patents.

The year 2023 marked another year of rapid advancements in quantum computing technology, showcasing significant progress in key areas such as scalable quantum computing and quantum error correction. Multiple physical realization approaches or modalities for creating quantum bits (qubits) are under development, offering different tradeoffs in performance metrics such as qubit count, error rate, decoherence time, and gate speed. Patenting activities are effective indicators of innovation speed and resource distribution in a technology field. As 2024 begins, this post explores the newest development focus and trends in the quantum computing industry through the angle of its patent landscape and discusses strategic considerations for patenting in this rapidly evolving field.

The U.S. Patent and Trademark Office (USPTO) today released guidance for determining inventorship of artificial intelligence (AI)-assisted inventions. As the Office has previously stated, the guidance clarifies that “while AI-assisted inventions are not categorically unpatentable, the inventorship analysis should focus on human contributions, as patents function to incentivize and reward human ingenuity.” The USPTO issued a call for comments on AI inventorship in February 2023. That Federal Register Notice (FRN) asked the public to respond to 11 questions, including “how does the use of an AI system [in the invention process]…differ from the use of other technical tools”; whether AI inventions may be patentable under current patent laws on joint inventorship by, for example, simply listing the natural person involved in inventions created by AI machines; and whether statutory or regulatory changes should be made to better address AI contributions to inventions.

The importance and profitability of diversity are already well-known by companies. Research conducted by McKinsey & Company shows that in 2019 companies in the top quartile for gender diversity on executive teams were 25% more likely to have above-average profitability than companies in the fourth quartile. However, when we look at diversity in the patent sphere, a report published by the World Intellectual Property Office (WIPO) showed that, in 2021, women accounted for only 16.5% of all inventors listed in Patent Cooperation Treaty (PCT) applications.

On February 8, the U.S. Court of Appeals for the Federal Circuit issued a precedential decision in Weber, Inc. v. Provisur Technologies, Inc. that vacated rulings by the Patent Trial and Appeal Board (PTAB) nixing validity challenges by American grill maker Weber against Provisur’s commercial food slicer patent claims. The Federal Circuit reversed the PTAB on claim construction and also found that the Board misapplied CAFC precedent on the level of public dissemination required before printed publications can qualify as prior art.
