This past August, Texas plaintiff Cobblestone Wireless, LLC filed a second trio of suits against AT&T (AT&T Mobility), Deutsche Telekom (T-Mobile), and Verizon (Verizon Wireless). In the first set of complaints, filed in December 2022, Cobblestone asserted four former Empire Technology Development LLC patents, but in April of this year, the plaintiff picked up a batch of patents from a new source, circling back to assert one of those patents against each of the three wireless carriers. Now, Cobblestone has accused Cisco (2:23-cv-00454), HP Enterprise (HPE) (Aruba Networks) (2:23-cv-00457), and CommScope (ARRIS) (2:23-cv-00455) of infringing that same, more recently acquired, “fifth” asserted patent.
