Patent No. EP3650758 (titled "Automatic Cooking Device And Method") was filed by Samsung Electronics on Jul 11, 2018. The application was issued on Apr 27, 2022.
An automatic cooking device comprises a light emitter capable of emitting multiple wavelength bands, a photographing unit with an image sensor, a memory, at least one processor, and a cooker. The processor executes instructions to control the light emitter and photographing unit to identify a food material's kind via vision recognition of a captured image. Subsequently, the processor selects a specific wavelength band based on the identified food kind and performs spectroscopic analysis of the reflected light to obtain the material's characteristic information. The processor then determines and controls a cooking process based on both the food kind and characteristic information, which the cooker executes. The system utilizes AI and machine learning for recognition and determination to automate the cooking operation.

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.
