Nilssen v. Osram Sylvania, Inc.

Ole K. Nilssen and the Geo Foundation, Ltd. (collectively, “appellants”) appeal from the judgment of the United States District Court for the Northern District of Illinois in favor of Osram Sylvania, Inc. and Osram Sylvania Products, Inc. (collectively, “Osram”) holding fifteen patents issued to Nilssen and exclusively licensed to the Geo Foundation unenforceable for inequitable conduct. Because the district court did not abuse its discretion, we affirm the court’s entry of judgment of unenforceability.
