Patent No. EP3855868 (titled "Method For Controlling The Power Supplied To An Induction Heating Coil Of An Induction Hob And Induction Hob") was filed by EGO Elektro Gertebau on Jan 22, 2020. The application was issued on Jul 17, 2024.
A method for controlling power supplied to a single induction heating coil of an induction hob for heating a pot involves adjusting power as a function of the relative position between the coil's center point and the pot base's center point. The induction heating coil is used to determine changes in this relative position, which serve as the basis for increasing or reducing the supplied power. The pot's initial position is arbitrary, provided it covers at least a portion of the coil. Power may be adjusted based on the distance between center points or changes in coverage area, potentially utilizing a quadratic correlation or analyzing electrical measures, such as load current and inverter voltage/power, to detect movement and coverage changes.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
