District Judge Dissents from CAFC Ruling for Amazon, Citing Claim Construction ‘Rabbit Hole’

On Friday, the U.S. Court of Appeals for the Federal Circuit issued a ruling in AlterWAN, Inc. v. Amazon.com, Inc. affirming a stipulated final judgment of noninfringement entered by the District of Delaware and dismissing AlterWAN’s challenges to the district court’s construction of claims directed to wide area network (WAN) implementation. Dissenting to the majority opinion was U.S. District Judge Arun Subramanian, sitting by designation from the Southern District of New York, who took issue with the majority’s judgment resting on non-claim terms inferred as limitations from vague specification language and irrelevant prosecution history.

The 24-Month Provisional: A Better Way for Inventors to Test the Market

Congress should let provisional applications be renewable for an extra year, and then publish them if a nonprovisional is not filed. Filing a nonprovisional is a big deal for small businesses. In some cases the expense pays off because it lets inventors recover from infringers, while in others it does not pay off because the market never develops. Under today’s law, the decision is mostly all or nothing—spend large amounts of money on attorney and United States Patent and Trademark Office (USPTO) fees, or compete in the market without protection.

CAFC Affirms Noninfringement Rulings on Spinal Implant Patents

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision Friday in Moskowitz Family LLC v. Globus Medical, Inc., affirming a district court’s grant of summary judgment of noninfringement, its construction of the claim term “universal,” and its denial of a motion for judgment as a matter of law (JMOL) of infringement.

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. But what does a notice letter need for it to count? How granular must it be? Are claim charts required?
