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.

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision on Thursday vacating the Trademark Trial and Appeal Board’s (TTAB’s) denial of a petition to cancel a trademark for a medicated tea product to treat colic in babies. Naterra International, Inc. petitioned the TTAB to cancel the mark BABIES’ MAGIC TEA based on likely confusion in the market with its own registrations for the mark BABY MAGIC, which cover “numerous toiletry goods.” The Board found that Naterra failed to prove confusion under the 13 DuPont Factors.

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 said in a precedential decision that the U.S. Patent and Trademark Office (USPTO) did not need to engage in notice-and-comment rulemaking to require trademark applicants and registrants to provide a physical street address with their trademark applications. The court took the case as an opportunity to directly address “when a rule is procedural and excepted from notice-and-comment rulemaking as a ‘rule[] of agency organization, procedure, or practice.’”

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.

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.

It was a busy week at the Patent Trial and Appeal Board (PTAB) with 40 new filings—all inter partes review (IPR)—and an average week in the district courts with 51 new filings. The bulk of new PTAB filings can be attributed to a few petitioners challenging multiple patents held by one patent owner (and all asserted in parallel district court litigations). For example, Apple continued its filings against Carbyne Biometrics LLC [associated with Bjorn Markus Jakobsson] patents, adding another five petitions against four patents to the two filed earlier this month

The U.S. Court of Appeals for the Federal Circuit (CAFC) today issued a precedential decision vacating and remanding a Patent Trial and Appeal Board (PTAB) decision that a patent for a climate control system was not proven unpatentable by Google LLC and Ecobee, Inc. In so doing, the court clarified how to determine when a court or the PTAB has implicitly construed a claim.

U.S. Patent and Trademark Office (USPTO) Director Kathi Vidal has released a guidance memorandum for the Trademark and Patent Trial and Appeal Boards (TTAB and PTAB) on the misuse of artificial intelligence (AI) tools before the Boards that largely clarifies the application of existing rules to AI submissions. The announcement is a precursor to a coming Federal Register Notice that will provide additional guidance on the use of AI tools for the public and other USPTO departments. The guidance document suggests that part of its impetus was Supreme Court Chief Justice John Roberts’ recent year-end report, which acknowledged both the benefits and dangers of AI in the context of the legal profession.

One day before comments closed on the Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights, published by the National Institute of Standards & Technology (NIST) and the Department of Commerce last month, the Department of Health and Human Services (HHS) denied an appeal of a decision not to march in on the blockbuster prostate cancer drug, Xtandi®.

The first software patent was granted in 1968. It’s now been three decades since the “Year of the Algorithm” in 1994, when cases such as In re Allapat, In re Lowry, and In re Beauregard initiated a wave of software patents. Well over half of U.S. patents granted annually are at least “software-related,” and even a cursory search of U.S. patents reveals software patents in fields ranging from encryption to speech recognition to network security. Why, then, do so many people continue to think that software cannot be patented at all? What explains the stark contrast between the long-standing legal reality and the beliefs of otherwise well-informed engineers, high-tech business people, and even some lawyers?

An en banc panel of the U.S. Court of Appeals for the Federal Circuit (CAFC) today heard arguments from LKQ Corporation, the U.S. government and GM Global Technology Operations in a case that could change the test for assessing design patent obviousness. The judges seemed interested in tweaking the existing “Rosen-Durling” test but struggled with getting the parties to clearly articulate a replacement approach that wouldn’t be potentially just as bad. The so-called Rosen-Durling test for design patent obviousness requires that, first, under In re Rosen (C.C.P.A., 1982), courts identify a prior art reference “the design characteristics of which are basically the same as the claimed design.” Next, under Durling v. Spectrum Furniture Co., 101 F.3d 100, 103 (Fed. Cir., 1996)), if such a reference is identified, the court must consider whether it can be modified based on other references to come up with “the same overall visual appearance as the claimed design.”

It was an average week for patent filings at the Patent Trial and Appeal Board (PTAB) and a slightly above-average week in district courts, with 62 district court complaints filed and 21 new PTAB petitions—one petition for Post Grant Review (PGR), and 20 for Inter Partes Review (IPR). The PTAB instituted 13 cases; iInstitution was denied in 12 cases and 15 cases settled. In district courts, 62 new cases were filed and 12 cases were terminated.
