  "title": "How Percy Spencer Invented the Microwave Oven",
  "original_title": "Method of treating foodstuffs",
  "summary": "This 1945 patent describes the process of using concentrated microwave energy to cook food, the fundamental technology behind the modern microwave oven.",
  "what_it_does": "The patent outlines a method for cooking food by generating electromagnetic waves specifically in the microwave range. It requires guiding and concentrating these waves into a restricted, enclosed space where the food is placed. By exposing the food to this concentrated energy for a specific duration, the internal temperature of the food rises, effectively cooking it.",
  "what_it_does_not_cover": [
    "Does not cover the specific electronic circuitry or magnetron design used to generate the waves.",
    "Does not cover methods of cooking that use infrared radiation or traditional convection heat.",
    "Does not cover the use of microwave energy for non-food applications like telecommunications or radar."
