Greenthread, LLC has filed cases against Cirrus Logic (1:23-cv-00369), Micron Technology (1:23-cv-00333), and Western Digital (1:23-cv-00326) over the provision of certain semiconductor memory products (i.e., dynamic random access memory (DRAM) and/or flash memory products). Six patents naming G.R. Mohan Rao as their sole inventor are asserted in the new District of Delaware cases; Greenthread has been litigating those same patents in a case originally filed in the Western District of Texas, still active there as to defendants Dell and Sony but from which claims against Intel were transferred to the District of Oregon. After transfer, though, a magistrate judge has adopted much of the work that Western District of Texas Judge Alan D. Albright completed—both before and after transfer—including claim construction. Meanwhile, a trial between Vervain, LLC and Micron over a different family of Rao patents, set to begin before Judge Albright next month, was just canceled.
