CAFC Rejects Apple’s Claim Construction and Partially Affirms Infringement of Wi-LAN Patents, But Orders New Damages Trial
On February 4, the United States Court of Appeals for the Federal Circuit (CAFC) affirmed in part, reversed in part, vacated in part, and remanded a patent infringement decision of the U.S. District Court for the Southern District of California that had awarded WiLAN, Inc. $85.23 million in damages from Apple Inc. Wi-LAN is the owner of two patents related to allocating bandwidth in a wireless communication system, U.S. Patent Nos. 8,457,145 (the ‘145 patent) and 8,537,757 (the ‘757 patent). In May 2014, Apple sued Wi-LAN in the Southern District of California seeking a declaratory judgment of non-infringement and invalidity for all claims of the ‘757 and ‘145 patents. Wi-LAN counterclaimed, asserting that certain Apple devices, including certain iPhone 5 and 6 models infringed claim 1 of the ‘757 patent and claims 9, 26, and 27 of the ‘145 patent based on their use of its Long-Term Evolution (LTE) wireless communication standard. Wi-LAN argued that the technology in the two patents at issue enabled Voice over Loong-Term Evolution (VoLTE), which enables voice call service over a 4G LTE network.
