Samsung (1:21-cv-01453) has filed a District of Delaware complaint seeking, among other things, declaratory judgments of noninfringement, invalidity, and unenforceability of four memory technology patents from a Netlist portfolio that has been in litigation since 2008. The case follows a May 2020 complaint that Netlist filed against Samsung in the Central District of California alleging breach of a November 2015 joint development and license agreement between the parties. Samsung’s case also drops after a ten-year stay in litigation between Alphabet (Google) and Netlist was lifted earlier this year, after the patent asserted there—one of the four subject to Samsung’s new complaint—emerged from extensive and multiple reexamination proceedings.
