An inventor-controlled NPE, Red Rock Analytics, LLC, has filed suit against Samsung (2:17-cv-00101), asserting a single patent (7,346,313) generally related to transceivers with a system for calibrating I and Q signals. At issue in the complaint are Samsung networking devices, mobile phones, and tablet and notebook computers with high data rate transceivers. Red Rock was formed in Massachusetts by John Herbert Cafarella, an MIT-trained electrical engineer named as an inventor on multiple patents.
