CAFC Affirms Eastern Texas Rulings of Noninfringement for Telecom Companies
On October 12, the United States Court of Appeals for the Federal Circuit (CAFC) issued two related precedential opinions affirming the decisions of the U.S. District Court for the Eastern District of Texas, holding that neither Verizon Wireless and Sprint Communications nor Nokia Solutions infringed Traxcell Technologies LLC’s patents. raxcell sued Verizon and Sprint for infringing four of its patents, all of which share a specification and a 2001 priority date. The four patents are U.S. Patent Nos. 8,977,284 (the ‘284 patent), 9,5,10,320 (the ‘320 patent), 9,642,024 (the ‘024 patent), and 9,549,388 (the ‘388 patent). In a separate suit, Traxcell sued Nokia for infringing the ‘284, the ‘320, and the ‘024 patents.
The claims of three of the four patents at issue—the ‘284, 320, and ‘024 patents (collectively the SON patents)—are related to self-optimizing network (SON) technology for making “corrective actions” to improve communications between a wireless device and a network.
