Headwater Research LLC has filed a second Eastern District of Texas case against Verizon (Verizon Wireless) (2:25-cv-00156), adding five more patents to a litigation campaign that already had 30. The plaintiff targets a wide array of products, including its cellular networks, servers, and services; eSIM provisioning and management components and systems; and eSIM-enabled devices ranging from smartphones to vehicle infotainment systems. A first trial in this campaign went against Headwater last month, with a second, again against Samsung, now set for April 2025. The parties there continue to contest, among other things, Headwater’s standing, Samsung arguing that Qualcomm is the true owner of this portfolio.
