EnOcean GmbH v. Face Int’l Corp.

EnOcean owns a patent application that claims a self-powered switch, which can be used to turn on and off lights, appliances, and other devices without a battery or connection to an electrical outlet. The named inventors originally filed a patent application disclosing the switch in Germany in 2000; in 2001 they filed a Patent Cooperation Treaty (PCT) international application with a similar disclosure. The Board of Patent Appeals and Interferences declared an interference in 2010 between EnOcean and Face, the real party of interest in a U.S. Patent that also claims a self-powered switch. The Board found the Face claims were unpatentable under 35 U.S.C. 103 based on prior art. Face did not appeal. The Board then applied a presumption that EnOcean’s claims were unpatentable for the same reasons. EnOcean’s argument for rebutting the presumption required determination that EnOcean’s claims could benefit from the filing dates of its German and PCT applications, eliminating a reference from prior art. The Board accorded no benefit of priority to the claims and found all of EnOcean’s claims unpatentable under section 103. The Federal Circuit vacated in part, finding that the Board erred in treating certain EnOcean claims as means-plus-function claims and in finding that certain EnOcean claim limitations lack support in its priority German and PCT applications.View "EnOcean GmbH v.
