Fujitsu v. Netgear, Inc was a patent infringement case centered around three patents claimed to be required for full compliance of the IEEE 802.11 (WiFi) standard and the WiFi Alliance Wireless Multi-Media (WMM) Specification. US patents 4.974,952, 6,018,642, and 6,469,993 were owned by Philips Electronics, LG Electronics, and Fujitsu respectively, and placed in the Via Licensing[1] pool. The Via Licensing pool claimed to hold all patents required for a complete WiFi/WMM implementation and Netgear did not enter an agreement with Via Licensing. Fujitsu sued claiming a complete implementation of the WiFi standard implied violating patents held by Via Licensing pool. When tried in United States District Court for the Western District of Wisconsin, the court granted summary judgment of non-infringement by Netgear for all three patents[2]; however, Fujitsu appealed the district court’s decision. The United States Court of Appeals for the Federal Circuit confirmed non-infringement for two of the three patent and found infringement of the third patent in four of Netgear's products [3] .
