Daingean Technologies Limited has filed a third complaint in the litigation campaign that it began this past March. Then, it sued AT&T (AT&T Mobility) in an Eastern District of Texas case in which Ericsson has since intervened. A July suit in the same district against Deutsche Telekom (Sprint, T-Mobile) followed, and now Daingean has hit Apple (3:23-cv-01560). Daingean operates under the Atlantic IP Services Limited umbrella; other such entities have repeatedly sued Apple in the Western District of Texas where the parties have engaged in long venue disputes, triggered each time by a motion to transfer for convenience; this time, the case has been filed directly in the Southern District of California.
