Opinions & Orders – April 23, 2025

This morning, the Federal Circuit released one precedential opinion and five nonprecedential opinions. In the precedential opinion, the court reversed a decision of the Patent Trial and Appeal Board based on an incorrect interpretation of the patent statute in the context of determining what qualifies as prior art for use in an inter partes review proceeding. Of the nonprecedential opinions, one comes in a vaccine case, one in an international trade case, one in a patent case appealed from the Patent Trial and Appeal Board, and two in patent cases appealed from district courts. Notably, Judge Stark filed additional views in the international trade case, indicating potential disagreement with the court’s law governing differential pricing analyses, while Judge Prost filed a concurring opinion in the nonprecedential opinion reviewing a decision of the Patent Trial and Appeal Board. Here are the introductions to the opinions.

Recent En Banc Activity

Here is an update on recent en banc activity at the Federal Circuit in patent cases. Since our last update, the court received a petition raising a question related to patent eligibility. The court also issued an invitation for a response to a petition raising a question regarding Article III jurisdiction to adjudicate patent infringement when the relevant patent has already expired. The court has also recently denied two petitions. The first denied petition raised a question concerning whether an abandoned patent application that becomes publicly available only after a challenged patent’s critical date is a printed publication that can form the basis for an inter partes review proceeding. The second denied petition raised questions concerning expert testimony to prove infringement of a means plus function element, claim construction, and the reverse doctrine of equivalents. Here are the details.
