This patent, originally for automated food preparation, now only protects a specific method for cooking or cooling food. It involves placing food on a thin, heat-conducting sheet, which then sits on a base designed to heat or cool it, potentially using air passages and a heating element.
Why it matters: The original broad automation claims were canceled. However, advancements in IoT and precise thermal control systems since 2020 could make the remaining specific conductive heating/cooling method more efficient or network-controllable.
