In re Burandt — Fed. Cir. (Oct 7, 2026)

No. 25-1336 Argued October 7, 2026 Published October 9, 2026

The Federal Circuit hears In re Burandt. Corliss Burandt developed technology for controlling valves in automobile engines. A related patent application was abandoned for years, then revived by the Patent Office in 2010. Revival returned it to examination; it did not guarantee a patent. Burandt says extra scrutiny under the Sensitive Application Warning System, or SAWS, unfairly stalled his application. The program sent selected applications for extra internal review. He is now challenging a Patent Trial and Appeal Board decision. Edward Pennington, of Pennington Oliak, represents Burandt. He will challenge the patent rejections and the way the application was handled.

In re Burandt (No. 25-1336) — U.S. Court of Appeals for the Federal Circuit, argued October 7, 2026.
