I’ve written in the past about a patent ownership stand-off, where, because of a mix-up in assignments and a disinterested possible co-owner, the interested owner cannot enforce the patent (original decision here and en banc decision here). The Supreme Court has refused to review the decision, so Ethicon, Inc. v. United States Surgical Corp., 135 F.3d 1456 (Fed. Cir. 1998) remains good law.
STC.UNM v. Intel, No. 14-717 (S. Ct. March 30, 2015) (cert. denied).
