Five Petitions, Five Denials: The Federal Circuit’s Mandamus Wall Grows Higher

CAFC, IPR, Patent

by Dennis Crouch

Five more mandamus petitions challenging IPR institution denials. Five more denials. In a series of nonprecedential orders issued between February 24 and 27, 2026, the Federal Circuit rejected every theory that petitioners offered for why the USPTO's discretionary denial of inter partes review should be subject to judicial oversight. The petitioners included major technology companies (Intel, Tesla), a Chinese communications firm (Kangxi Communication Technologies), an education technology company (Kahoot!), and a startup founded by the very inventors of the patents it sought to challenge (Tessell). Each presented a different factual scenario and a different legal theory. None succeeded. In re Kangxi Communication Technologies (Shanghai) Co., Ltd., No. 2026-115 (Fed. Cir. Feb. 24, 2026); In re Intel Corp., No. 2026-113 (Fed. Cir. Feb. 24, 2026); In re Tessell, Inc., No. 2026-117 (Fed. Cir. Feb. 24, 2026); In re Kahoot! AS, No. 2026-119 (Fed. Cir. Feb. 25, 2026); In re Tesla, Inc., No. 2026-116 (Fed. Cir. Feb. 27, 2026).
