Headwater Partners II LLC has sued AT&T (AT&T Mobility and other subsidiaries) (2:24-cv-00016), Deutsche Telekom (Sprint, T-Mobile) (2:24-cv-00015), and Verizon (Verizon Wireless and other subsidiaries) (2:24-cv-00007) over two patents naming Gregory Raleigh as an inventor. Targeted in the new trio of Eastern District of Texas complaints are certain features (e.g., 5G NR adaptive beamforming and 5G NR Integrated Access Backhaul (IAB)) through the provision/use of certain telecommunications equipment—including 4G LTE and 5G cellular base stations manufactured by Ericsson, Nokia, and/or Samsung, as well as 4G LTE and 5G nodes. Headwater Research LLC is already in litigation, over other Raleigh patents, against these same defendants, as well as against Lenovo (Motorola Mobility) and Samsung.
