Iridescent Networks, Inc. v. AT&T Mobility, LLC, No. 18-1449 (Fed. Cir. 2019)
Annotate this CaseIridescent’s 119 patent, entitled “System and Method of Providing Bandwidth on Demand,” is directed to a system and method of network communication that provides guaranteed bandwidth on demand for applications that require high bandwidth and minimizes data delay and loss during transmission. In Iridescent’s infringement suit against AT&T, the parties stipulated to noninfringement based on the district court’s construction of the term “high quality of service connection.” The Federal Circuit affirmed. The term “high quality of service connection” is a term of degree that is limited to the minimum connection parameter requirements disclosed in Figure 3 of the 119 patent. The term means “a connection that assures connection speed of at least approximately one megabit per second and, where applicable based on the type of application, packet loss requirements that are about 10-5 and latency requirements that are less than one second.”
