Nearly three years after an adverse Federal Circuit ruling in the first wave of its sole litigation campaign, X2Y Attenuators, LLC has filed a third district court case against Intel (1:17-cv-00164). The new complaint asserts two patents (8,587,915; 9,036,319) not seen previously in this campaign, which began in May 2011 with an ITC investigation and a district court case, both initially asserting five earlier patents from the same 66-member family to which the ‘915 and ‘319 patents belong against Intel and two of its customers, Apple and HP. All of the patents generally relate to certain circuit structures for reducing electromagnetic interference; accused of infringement throughout the campaign have been Intel’s Core i3, i5, i7, and Xeon microprocessors, with Apple and HP products incorporating those microprocessors also accused in the earlier phase.
