Individual inventor James B. Goodman has added a case against Samsung (4:17-cv-00455) to the litigation campaign that he started over a decade ago. The new complaint asserts a single patent (6,243,315), targeting computing devices that contain certain memory devices (DDR3 and DDR4). The ‘315 patent generally relates to volatile memory systems that have the capability to retain some data during low power situations. Goodman accuses the Samsung memory products of infringement through compliance with relevant JEDEC standards. The inventor’s latest complaint identifies Samsung as one of his prior licensees, but court filings in recent, parallel cases suggest that that license expired, as long ago as 2003.
