Federal Circuit Affirms Dismissal of Pro Se Inventor’s Patent Term Adjustment Suit as Untimely

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.

The Patent Estate Problem: Why Litigation Finance Is the Only Preservation Tool American Inventors Actually Have

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.

What Does a Patent Notice Letter Actually Require? Understanding ‘Actual Notice’

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.

ARIPO vs. OAPI: What U.S. Companies Need to Know Before Building an Africa IP Strategy

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.

CAFC Affirms Fee Award Over Deficient Patent Pre-Suit Investigation

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.
