Last November, with apparent backing by a litigation funder, Apex Beam Technologies LLC filed its first patent case, suing TCL (TCT Mobile) in the Eastern District of Texas, where the Texas plaintiff has now expanded the litigation into a campaign by adding suits against OnePlus (2:22-cv-00031) and ZTE (2:22-cv-00032). The same five wireless communications patents are asserted against each defendant, with infringement allegations targeting the provision of 5G mobile phones and/or tablets.
