Intellectual Ventures I LLC v. T-Mobile USA, Inc.

IV’s 248 patent describes “an application-aware resource allocator” that allocates bandwidth resources to transmit information from software applications over a packet-switched network. The patent explains that quality of service (QoS) requirements may vary among applications, with some types of applications demanding, for instance, error minimization, and others prioritizing speed. To meet these varying requirements, the application-aware resource allocator “allocates bandwidth resource to an application based on an application type.” The district court rejected an infringement suit on summary judgment. The Federal Circuit vacated in part. The plain meanings of “application-aware resource allocator” in claim 1 and “application-aware media access control (MAC) layer” in claim 20 permits the resource allocator to allocate resources based on application type, which can be discerned using information from any of network layer 3, transport layer 4, and application layer 7. The district court’s grant of summary judgment of non-infringement resulted from a contrary construction. The court affirmed a determination that the “allocating means” in claim 20 are indefinite. The patent described QoS as “subjective” and varying based on individual preferences; the patent does not “provide adequate guidance.” View "Intellectual Ventures I LLC v.
