TracBeam’s first suits in 2014 target Apple and T-Mobile. Four patents are asserted in the suits, including two patents that have not been previously asserted (7298327, 7525484, 7764231, 8032153). The patents-in-suit relate to wireless geolocation using multiple location estimators. Location services available on defendants’ mobile devices and on T-Mobile’s service network are at issue in the suits. TracBeam developed the patents-in-suit, and all four have a priority date in 1996. It began its litigation in 2011, suing a variety of mobile device companies and service providers, including AT&T, Google, Sprint, and Verizon. The current suits are the first since that initial filing. 8/8, Eastern District of Texas, 6:14cv00678, 6:14cv00680
