The Federal Circuit has decided to review en banc a panel's decision requiring Google to pay $20 million to EcoFactor for infringing a smart thermostat patent. This rare full-court review comes after Google argued that the court's previous ruling allowed patent owners to 'manufacture a royalty rate.' The original decision, made by a three-judge panel, awarded EcoFactor just over $20 million in damages in 2022. The case revolves around Google's Nest smart thermostats and has significant implications for patent litigation in the tech industry. Google persuaded the Federal Circuit to reassess its trial loss to EcoFactor.
