Its prior case against Samsung stayed in light of a set of inter partes reviews (IPRs) of the five former Shanghai Langbo Communication Technology patents-in-suit, Apex Beam Technologies LLC has filed a second complaint against Samsung asserting a dozen patents from a different source against the provision of a long list of “5G mobile handsets, tablets, and notebooks”. In a parallel action against TCL (TCT Mobile), not stayed in light of those IPRs, Apex Beam has moved to amend the complaint to add five of those newly sourced patents. TCT Mobile has opposed that motion, through a sur-reply filed with Eastern District of Texas Chief Judge Rodney Gilstrap at the end of February.
