  "title": "How Georges Claude Invented the Neon Light",
  "original_title": "System of illuminating by luminescent tubes.",
  "summary": "A 1915 patent describing the use of neon gas in sealed glass tubes to create bright, colorful light for signs and illumination.",
  "what_it_does": "The patent details a method for creating electric light by sealing neon gas inside a glass tube with electrodes at each end. When high-voltage electricity flows through the gas, it ionizes the neon, causing it to glow with a characteristic bright red-orange light. The invention specifically addresses the purification of the gas and the design of the electrodes to prevent the gas from being absorbed into the glass walls during operation, which was a major hurdle for early gas-discharge lamps.",
  "what_it_does_not_cover": [
    "Does not cover the use of gases other than neon for illumination",
    "Does not cover modern LED-based signage that mimics the look of neon",
    "Does not cover low-voltage lighting systems"
