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?
This week on IPWatchdog Unleashed, I spoke with Hilary Preston. Our conversation focused on the rapidly expanding AI data center ecosystem and the technology, infrastructure, and intellectual property risks emerging as billions of dollars flow into the sector.
The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision today in Ironburg Inventions Ltd. v. Valve Corporation, reversing a district court ruling that had estopped Valve Corporation from asserting two invalidity grounds at trial. The majority opinion, authored by Judge Hughes, concluded that the district court relied on insufficient evidence to estop one ground and failed to adequately account for hindsight bias in estopping the other. Judge Stark filed a concurring opinion.
This week on IPWatchdog Unleashed, I speak with Martin Correa. Correa, who leads foresight work at the World Intellectual Property Organization (WIPO). Correa’s job is not to predict the future of IP, but to consider what futures are possible so WIPO and Member States can be better prepared for whatever eventuality does materialize. And since there is no data about the future—as he puts it—his work uses signals of change, horizon scanning and competing scenarios to expose assumptions and identify the decisions that could push the IP system in one direction or another.
Patent monetization is often discussed as if the hard part begins when a patent owner makes the decision to license, sell, finance, or enforce its patent assets. That is a mistake and demonstrates a lack of understanding of the difficulties and complexities of patent monetization. By the time a patent owner is sitting across the table from a potential licensee, buyer, lender, litigation funder, or accused infringer, much of the outcome has already been fully determined. The real work begins years earlier in preparation for monetization.
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.
The United States patent system is not failing because Americans have stopped inventing. It is failing because the legal and institutional architecture built to protect invention no longer operates as a coherent innovation framework. Over time, the system has become a patchwork of overlapping tribunals, inconsistent legal standards, procedural inefficiencies, and doctrinal barriers that make it harder to obtain, defend, enforce, license, and rely upon even high-quality patent rights covering innovations of extraordinary consequence. Now in the coming months we will move forward with a candid, serious, historically grounded, and focused conversation on building—not merely patching—the next American patent system.
Recent amendments to Federal Rule of Evidence 702 did not invent the trial judge’s gatekeeping obligation, nor did they transform economic analysis. They did, however, sharpen the focus on the burden of establishing admissibility and whether an expert has reliably applied a valid methodology to the facts. Combined with the Federal Circuit’s increasingly demanding review of patent damages opinions, the practical message is unmistakable: the economic case must be engineered from the beginning, or you will surely suffer the consequences only after it is too late.
The mythology surrounding the act of invention tends to concentrate on the breakthrough moment. There is a flash of insight, a sketch is made on a cocktail napkin, the prototype is assembled in a garage to prove the brilliance of the concept. Unfortunately, commercial markets are considerably less romantic. They do not reward ideas merely because they are clever, patentable or even technically superior. They reward products that work, solve a problem customers recognize, can be manufactured at an economically sustainable price and generate an acceptable return for whoever assumes the risk of bringing them to market.
