Powertech Tech., Inc. v. Tessera, Inc.

by
Defendant's process patent is directed to methods for preventing the contamination of exposed semiconductor chip terminals during encapsulation of the chips in molded plastic. Plaintiff, one of defendant's licensees, sought a declaration of non-infringement. The parties have been involved in other litigation. The district court dismissed for lack of subject matter jurisdiction. The Federal Circuit reversed. The dispute between the parties, as to whether the license agreement requires royalty payments to be tied to valid patent coverage, is sufficient to support declaratory judgment jurisdiction.
