In STC.UNM v. Intel Corp., Fed. Cir., No. 2013-1241 (June 6, 2014), The Federal Circuit found that the plaintiff patent owner did not have standing for its infringement claims because one of the four co-owners had not been joined and could not be involuntarily joined.

A joint assignment made two years prior to issuance incorrectly identified all four inventors as UNM employees. This was subsequently corrected with an assignment by UNM to Sandi Corp. Before the issuance of the ‘321 patent, two of the UNM inventors filed another patent, U.S. Patent No. 6,042,998, that incorporated the ‘321 patent by reference and issued in 2000. During the prosecution of the ‘998 patent, the PTO rejected the application for double-patenting in view of the ‘321 patent. UNM filed a terminal disclaimer to overcome the double-patenting rejection, which represented that “any patent granted on this instant application shall be enforceable only for and during such period” that the two patents were commonly owned, and that UNM was “the owner of record of a 100 percent interest.” However, Sandia never claimed ownership in the ‘998 patent.
