Cypress Lake Software, Inc. has filed suit against Samsung (6:18-cv-00016) for a third time, accusing the tech giant of infringing 13 patents through the manufacture and sale of smartphones, tablets, and laptops “that come installed with, or can be upgraded to, Google’s Android or Chrome operating systems”. Filed in November 2015 as part of a wave of filings in advance of the take-effect date for certain changes to the Federal Rules of Civil Procedure, Cypress Lake’s first case against Samsung was dismissed without prejudice in March 2016. The second, October 2016 suit focused infringement allegations on desktop and tablet computers running Microsoft’s Windows 10; it was dismissed with prejudice in August 2017, apparently as a consequence of a wider resolution between Cypress Lake and Microsoft. The NPE pleads that the six patents now asserted, which were previously asserted against Samsung, cannot be challenged by the defendant in an inter partes review (IPR), as more than one year has passed since that earlier suit.
