On the heels of settlement in a case brought this past March against Dell, Modern Telecom Systems, LLC has added three cases to its campaign over a single, long-litigated patent characterized as a “learning sequence patent”, generally related to synchronization signals exchanged by network interfaces (in the past, dial-up modems) to learn how to communicate with one another. The new defendants are Barnes & Noble (1:17-cv-01725), Panasonic (1:17-cv-01724), and Sony (1:17-cv-01722). Modern Telecom’s complaints target a wide variety of Wi-Fi-enabled computing devices (in the latest complaints, certain phones, tablets, televisions and Blu-Ray players of Sony; still and video cameras and tablets of Panasonic, and Barnes & Noble’s NOOK Tablet and NOOK Glowlight), alleging that operations compatible with particular Wi-Fi standards infringe.
