The U.S. Court of Appeals for the Federal Circuit (CAFC) in a precedential opinion today affirmed a district court’s judgment that AT&T Mobility LLC did not infringe an inventor’s wireless communications technology patent but held that AT&T had forfeited its chance to prove the patent is invalid on appeal. Joe Salazar’s U.S. Patent No. 5,802,467 is titled, “Wireless and Wired Communications, Command, Control and Sensing System for Sound And/or Data Transmission and Reception.” After unsuccessfully suing HTC Corp. for infringement in 2016, Salazar sued HTC’s customers, AT&T, Sprint, T-Mobile and Verizon, in 2019, alleging certain phones sold by the companies infringed his patent. A jury ultimately found that the companies did not infringe but that the patent was not invalid as anticipated.
