Patty reads your codebase and prepares a US provisional patent application: the specification, the drawings and the cover sheet. You sign and file it yourself. Once it is filed, you can say patent pending.
An AI draft that guesses is worse than no draft. Patty’s has to point at your source, line by line, or it does not get built.
Your AI tool writes down each mechanism it finds, with the exact lines it came from. Patty opens every one and compares the text.
## E1. Two-stage eviction Expired entries are removed first. - src/cache.ts:22 | Expired entries go first - src/cache.ts:23-29 | if (store.size < MAX) return;
Example of an evidence entry.
The check fails the packet when:
Black on white, numbered, one figure per sheet, the way a patent drawing looks. Every numeral in a drawing has to appear in the text, and the reverse.

It maps the code, writes the specification from the evidence, draws the figures, searches patents and runs the check.
Read it. Then sign, submit and pay in your own USPTO account, with every field and step written out for you.
Patty writes a packet into your repo. Two PDFs are the filing copies. The rest tells you what to type and when your deadlines are.
Patty was pointed at its own repository. Six minutes later it had a provisional application for its own checker. The checker failed the first draft: one citation was off by a single line.
PREPARED BY PATTY · FILING IS THE INVENTOR’S STEPUSPTO guidance says a signature is entered personally by the person signing. A tool cannot apply it.
A USPTO account belongs to one person. Patty hands you the numbered steps and every field.
The government fee is yours, paid in your own account. Patty is free and takes no card.
Patty is not a law firm and this is not legal advice. A provisional application is not a patent.
Patty runs a first knockout check on a name across domains, package registries and Wikipedia, and writes the fields for a US trademark application. It does not search the USPTO register.
It is a real patent application. A provisional application is never examined and never becomes a patent on its own. Filed by you, it holds your filing date for twelve months. To pursue a patent you file a full application within that time.
Yes, once you have filed the application with the USPTO. Not before.
You need a codebase and an AI coding tool such as Claude Code, Cursor or Codex. Patty plugs into it, and you ask in plain English.
Patty’s server sends no source code anywhere and has no telemetry. A patent search sends your query text to Google Patents. A trademark check sends the name to public registries. The AI tool you run Patty in reads your code under its own terms.
No. Patty is software that prepares documents for you to file yourself. It does not give legal advice. You can take the packet to a patent attorney before you file.
No. It is a quick keyword search of patents. It is not a patentability search and it does not cover papers, products or repositories. Finding nothing does not mean an idea is new.
Patty is free. Government fees are separate, and you pay them yourself in your own USPTO account.
