Also, the district court allowed Fujitsu's expert witness to demonstrate a WiFi system configured to transmit an alert signal every 102 milliseconds. The district court reported that the Netgear system remained on as long as a "more data" flag or the alert beacon was enabled. If the beacon was inactive or the "more data" flag was not set, the system immediately powered down. This proved Netgear's system does not have a fixed data receive-ready period. Judgment by the court of appeals for the federal circuit During the appeal, Fujitsu claimed "synchronously" does not mean "at the same time". Instead, Fujitsu stated "synchronously" means: "the shifting to a power-on state has a temporal relationship with the beacon signal so that the beacon signal can be received." In addition, Fujitsu argued that the district court's definition of "synchronous" would require two events to occur at precisely the same time which they stated is a physical impossibility. Netgear argued the district court's interpretation was correct. The circuit court defined synchronous to mean "just before or at the same time" and thereby slightly relax the limitation. Given the evidence from the district court's experiment, however, the circuit court affirmed the district court's grant of summary judgment of non-infringement without modification. Analysis of the courts on US patent 993 Patent claim analysis (Clarification of the terms used in claim) The final patent under consideration is 6,469,993 owned by LG Electronics. This patent described a system for quality of service in a communications network where the base station assigns priority to different clients and traffic types. Specifically, the LG patent grants individual terminals priority levels. Here, the important fact is that the priority to determine which data would be received first is assigned at the terminal level. Patent infringement analysis by the district court LG electronics argued that Netgear products that implemented WMM Specification infringed its 993 patents. The WMM Specification is a complement to the 802.11 standard that outlines a set of structures and methods to ensure better quality of service within an 802.11 compliant network. However, the district court held that the accused products did not infringe the patent because the WMM Specification states that priority is assigned to message types, but not to individual terminals as described in the 993 patent. Judgment by the court of appeals for the federal circuit The appeals court affirmed the district court's judgment of non-infringement for US
