Opinions & Orders – May 12, 2026

Late yesterday, the Federal Circuit released a nonprecedential opinion in a patent case appealed from the Patent Trial and Appeal Board in an inter partes review proceeding. In this case, a majority of the panel found all relevant claims unpatentable. Notably, Judge Taranto concurred in part and dissented in part, taking the position that the panel should not have reversed the PTAB’s judgment on certain patent claims. This morning, the court released three nonprecedential opinions, one nonprecedential order, and two Rule 36 summary affirmances. One of the nonprecedential opinions comes in a patent case appealed from the Eastern District of Texas, one comes in a case appealed from the Merit Systems Protection Board, and one comes in a government contract case appealed from the Court of Federal Claims. The nonprecedential order comes in a veterans case appealed from the Court of Appeals for Veterans Claims. Here are the introductions to the opinions and the order as well as links to the summary affirmances.
