Ten days after a similar suit (5:16-cv-00566) was filed by Supermicro in the Northern District of California, Intel and its subsidiary McAfee have filed a declaratory judgment action (2:16-cv-00028) against Computer Protection IP, LLC (CPIP). The complaint alleges that the NPE sent McAfee and other Intel customers a letter (attached to the filing) on December 23, 2015 threatening to initiate litigation should McAfee not take a license to a single patent (8,468,591) by February 17, 2016. The ‘591 patent generally relates to server security, and CPIP’s letter attaches charts comparing McAfee products that use Intel’s Trusted Execution Technology (TXT) and Cloud Integrity Technology (based on TXT) against claims 39 and 41-44 of the patent.
