Through two concurrently filed Eastern District of Texas complaints, Headwater Research LLC has accused AT&T (AT&T Mobility) (2:23-cv-00397, 2:23-cv-00398) of infringing the same four mobile data management patents that it asserted against Verizon (Verizon Wireless) in late July and against Deutsche Telekom (Sprint, T-Mobile) in late August. All these cases have been filed in the same district, targeting the provision of “electronic devices, including mobile phones and tablets . . . as well as cellular networks, servers, and services”. A couple of days earlier, Headwater also filed suit against Lenovo (Motorola Mobility) (4:23-cv-04496) in the Northern District of California, adding two more patents from the same family of over 200 to those litigated in this growing campaign.
