Inventor-controlled Red Rock Analytics, LLC has filed a second suit in the litigation campaign begun in February 2017, suing Apple (2:19-cv-00117) in the Eastern District of Texas over the same patent. That patent broadly concerns transceivers with a system for calibrating I and Q signals, with infringement allegations in the new complaint focused on devices—various models of iPhone, iPad, iPod touch, Apple Watch, Airport, Time Capsule, and Mac as well as the Homepod—compliant with the 802.11n Wi-Fi standard and with later versions of Wi-Fi (“e.g. 802.11ac, 802.11ad, and/or 802.11ax”), including “802.11n and later wireless transceivers made by Broadcom”. This new case follows as the prior suit, filed against Samsung in the same district, appears to be headed toward dismissal on the eve of trial.
