The start of 2022 has seen yet another round of litigation in the smart thermostat campaign of EcoFactor, Inc. The patent holder has filed new suits against familiar defendants Alarm.com (Pointcentral) (6:22-cv-00055), Alphabet (Google) (6:22-cv-00032), ecobee (6:22-cv-00033), Vivint (6:22-cv-00034), and Resideo Technologies (6:22-cv-00069), as well as a first suit against new defendants Amazon (6:22-cv-00068) and LG Electronics (8:22-cv-00103). This campaign started in 2019, with prior rounds of litigation either centering around or sandwiched between two investigations before the International Trade Commission (ITC), one ending with no violation found (337-TA-1185) and the other having seen a December 2021 evidentiary hearing (337-TA-1258). This latest round is further complicated, as earlier rounds have been, by competing declaratory judgment actions, one filed by ecobee (1:22-cv-10049) and another by Google (5:22-cv-00162).
