Atlantic IP Services Limited has begun litigating the former Siemens patents that it received from a Fortress Investment Group LLC vehicle this past October. The Dublin-based monetization firm’s Ollnova Technologies Limited has filed suit against Alphabet (Google) (6:22-cv-00246) in the Western District of Texas, Carrier (9:22-cv-80388) in the Southern District of Florida, and ecobee (2:22-cv-00072) in the Eastern District of Texas, targeting the respective provision of various smart home products (primarily thermostats) with overlapping subsets of five such former Siemens patents. With these suits, Ollnova joins eight other Atlantic IP entities to litigate former operating company assets, including Arigna Technology Limited, which recently added a case against TCL (6:22-cv-00217) to one of its many such campaigns, and Sonraí Memory Limited, which just hit AMD (6:22-cv-00229) with a former Atmel patent following additional lawsuits filed against existing defendants Amazon (6:22-cv-00225), Dell (6:22-cv-00188), Kingston Technology (6:22-cv-00192), LG Electronics (LGE) (6:22-cv-00187), and Samsung (6:22-cv-00189).
