WI-LAN USA, Inc. v. Apple Inc.

by
Wi-LAN’s patents result from advances proposed for the WiMAX wireless network standard. In a typical wireless network, a base station connects directly to the user devices that it serves. The patents to add intermediary nodes between the base station and the user devices. Communications from the base station to a user device pass from the base station through an intermediary node to the user device; communications from a user device to the base station take the reverse path. This network architecture allowed for efficiency gains, primarily because the base station could offload some of its more resource-intensive tasks to the intermediary nodes. Wi-LAN claimed infringement by Apple’s iPhone operating on a 4G network. Based on several claim constructions, the district court granted Apple summary judgment of noninfringement. The Federal Circuit affirmed, upholding the court’s construction of the term “specified connection” and the term “UL connections.” View "WI-LAN USA, Inc. v. Apple Inc." on Justia Law
