The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision today in Guymon v. Squires, affirming a decision from the U.S. District Court for the Eastern District of Virginia dismissing with prejudice an inventor’s lawsuit challenging a patent term adjustment (PTA) determination. Circuit Judge Hughes wrote for the court, joined by Chief Judge Moore and Circuit Judge Lourie, and rejected each of the three arguments that Guymon raised on appeal.

Congress and the courts have spent two decades treating patents as active weapons in an ongoing commercial fight. That framing misses what patents actually are to most of the people who own them: inheritable property. Twenty-year terms outlast careers. Portfolios pass to spouses, children, foundations, and trusts. Licensing income can support a family for a generation after the inventor stops working…. The pending fights over funder disclosure — Suggestion 26-CV-8 before the Advisory Committee on Civil Rules, the USITC’s proposed 19 C.F.R. § 210.14a, and S.3826, the Litigation Funding Transparency Act of 2026 — are not really arguments about transparency. They are arguments about whether a solo inventor’s family keeps what the inventor spent 30 years building.

To prevent innocent individuals from being held liable while acting in good faith, the patent statute requires that patent owners put would-be infringers on notice of their intellectual property rights before they are able to hold them liable for any acts of infringement. But what does a notice letter need for it to count? How granular must it be? Are claim charts required?

Yesterday, the World Intellectual Property Organization (WIPO) released its 2026 Global Innovation Index (GII) identifying metropolitan clusters around the world seeing the highest levels of innovation activity as judged by publications and R&D investments. This year’s Index underscores the growing tech dominance of China, which accounted for one-quarter of the top 100 innovation clusters in this year’s survey of top tech and innovation hubs around the world.

Every year, U.S. companies expanding into Africa make the same planning mistake: they treat the continent as though it has one intellectual property system. It has two, and choosing the wrong one, or failing to choose at all, can leave a brand or invention unprotected across dozens of countries a company assumed it had already covered. Africa is the only continent with two regional IP registration systems operating side by side. Understanding the difference between them is not a technical footnote. It is one of the first strategic decisions a U.S. company should make before it files anything.

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision today in Viavi Solutions Inc. v. Platinum Optics Technology Inc., affirming a Northern District of California ruling that awarded attorney’s fees to Platinum Optics Technology Inc. (PTOT) after finding Viavi Solutions Inc. litigated its patent infringement claims in a manner that met the standard for an “exceptional” case under 35 U.S.C. Section 285.

Under 35 U.S.C. Section 256, one can only correct an inventorship error when the underlying facts and the affected parties can actually be identified, and when the statutory correction procedure can be completed. AI-assisted invention is starting to produce cases where none of that is possible: the development record shows plenty of human activity, but nothing in it establishes which person actually conceived the claimed invention. After Fortress Iron, LP v. Digger Specialties, Inc., No. 2024-2313 (Fed. Cir. Apr. 2, 2026, that kind of gap can turn into a validity problem, not just a paperwork one.

In a previous article, the authors showed that Chinese courts ask a different question than U.S. courts — not whether the inventor possessed what is recited in the claim, but whether the scope of the claim matches the Technical Solution that the invention actually contributed to the advance of the art. This difference in underlying premise leads to one conclusion: a U.S.-style specification needs to be adjusted when filed in China. Below, the authors propose several strategies, offered as their personal views.

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision today in Biofer S.p.A. v. Vifor (International) AG affirming a judgment of non-infringement by the U.S. District Court for the Eastern District of New York in favor of Swiss Pharmaceutical company, Vifor (International) AG. The dispute centered on the construction of a claimed pH range recited in a patent covering a process for producing iron-sugar complexes used to treat iron deficiency.

Yesterday, the U.S. Court of Appeals for the Federal Circuit issued a ruling in Vieth v. MOM Enterprises, LLC affirming the Patent Trial and Appeal Board’s (PTAB) invalidation of Elaine and Dr. Reinhold Veith’s patent claims to methods of administering vitamin D to human beings. The Federal Circuit agreed that most of the claim construction and prior art arguments raised by the Vieths on appeal were forfeited for not being properly developed in the proceedings below, and also dismissed the Vieths’ contentions that they had established nexus between industry praise for its products and the challenged method claims.

The House Judiciary Committee’s Subcommittee on Courts, Intellectual Property, Artificial Intelligence, and the Internet held an oversight hearing today to consider its role in renewing the U.S. Patent and Trademark Office’s (USPTO’s) fee setting authority. Throughout the hearing, Subcommittee Chairman Darrel Issa (R-CA) expressed skepticism about USPTO Director John Squires’ recent changes to discretionary denial practice at the Patent Trial and Appeal Board (PTAB) and wondered whether renewal of such authority under the America Invents Act (AIA) should be conditioned on reforms to the agency’s policy.

Many Worlds 2T Innovations LLC has filed a patent infringement lawsuit against OpenAI OpCo, LLC, alleging that OpenAI’s artificial intelligence products and services infringe five AI patents covering personalized search, vector-based retrieval, recommendation systems and probabilistically controlled content generation. The complaint, filed August 31, 2026, in the U.S. District Court for the Eastern District of Texas, Marshall Division, seeks a jury trial, monetary damages in the form of past and continuing royalties, enhanced damages for alleged willful infringement, and an injunction prohibiting continued infringement.

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision today in Netlist, Inc. v. Micron Technology, Inc., affirming a Patent Trial and Appeal Board (PTAB) final written decision that found all challenged claims of a Netlist computer memory patent unpatentable as obvious. The court rejected Netlist’s arguments that the Board’s findings lacked substantial evidentiary support and that the Board violated the Administrative Procedure Act (APA) in reaching its conclusions.

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision on Monday in Exelixis, Inc. v. MSN Laboratories Private Ltd., affirming a district court finding that certain patent claims covering a cancer treatment satisfy the written description requirement under 35 U.S.C. Section 112(a). The court also granted a motion to dismiss a separate portion of the appeal as moot and vacated the underlying district court judgment on that issue.
