Inventor-Controlled Plaintiff Initiates Litigation over “3D Memory” Products

Inventor-controlled MonolithIC 3D Inc. has filed its first litigation with cases against KIOXIA (2:25-cv-01160) and SK hynix (2:25-cv-01167; 2:25-cv-01176) in the Eastern District of Texas. The 18 patents-in-suit, asserted in overlapping sets, are described by the plaintiff as generally related to “semiconductor memory devices and fabrication methods”. The defendants are accused of infringement through the provision of “products comprising 3D memory”, including at least all “3D NAND memory” and/or “high bandwidth memory”.
