Thousands of patents are abandoned every year — and the ideas inside them are still good. AutoInvent shows you fifteen of them every morning. Real inventions, with the original drawings. FIND SOMETHING WORTH BUILDING A new wall of fifteen abandoned patents each day, chosen around the industries you care about. Every one is a real filing with real figures, explained in plain language instead of legal drafting. HOLD IT WHILE YOU THINK Found one you like? Hold it for 48 hours. It stays out of everyone else's feed while you decide. MAKE IT YOURS Pick a direction — make it smarter, make it cheaper, take it to a new market — and AI reworks the invention into your own version. Your changes, grounded in what the original actually claimed. CAPTURE IDEAS THE MOMENT THEY ARRIVE Say an idea out loud and it's written up and waiting in your log. Type one if you'd rather. Everything you save, reinvent, or file lives in one place. PROTECT IT Turn an idea into a provisional patent application, drafted with AI and formatted for the USPTO. Lock in your filing date, then decide about the full application within twelve months. WHO IT'S FOR Independent inventors, product people, entrepreneurs had an idea at 11pm and no way to do anything with it. AutoInvent is not a law firm and does not provide legal advice. Filing a patent application is your decision. SUBSCRIPTION AutoInvent Pro unlocks the full daily wall, unlimited AI reinventions, and provisional patent drafting. • Monthly — $39/month • Annual — $300/year (save 36%) A 3-day free trial is included. Payment is charged to your Apple ID at confirmation of purchase. Your subscription renews automatically unless cancelled at least 24 hours before the end of the current period.
