Headwater Research Sues the Major Wireless Carriers for a Third Time This Year

On the heels of a $278.8M jury verdict in an earlier case against Samsung, Headwater Research LLC has filed another round of suits against AT&T (AT&T Mobility) (2:25-cv-00464), Deutsche Telekom (Sprint, T-Mobile) (2:25-cv-00462), and Verizon (Verizon Wireless) (2:25-cv-00463), all in the Eastern District of Texas as well. These May cases follow a trio of April ones—AT&T (AT&T Mobility) (2:25-cv-00428), Deutsche Telekom (Sprint, T-Mobile) (2:25-cv-00359), and Verizon (Verizon Wireless) (2:25-cv-00391)—that themselves followed a trio of February suits against the same three defendants.
