The Expired Patent Arbitrage System

@gippp69 uses Claude to filter millions of public domain patents for commercial viability. By scraping the USPTO Bulk Data portal and scoring expired utility patents based on manufacturing complexity and Amazon gaps, he identifies products that once worked but stopped being made. Examples include a self-watering planter ($1.80 cost vs $14 retail) and a snap-lock collapsible pet bowl ($0.95 cost). It is a pure arbitrage play: $0 for the blueprint, high margins on Amazon.
