How do I file a patent from ChatGPT?

You file a patent from ChatGPT the same way as from Claude: connect ChatGPT to a patent platform whose attorneys do the filing, then run the disclosure, review and approval steps in the chat. With Lightbringer:

1. Sign up free at app.lightbringer.com and have an administrator enable MCP access for your organisation under Advanced Settings.
2. In ChatGPT, search for Lightbringer in the apps and plugins directory, click Install, sign in with email, Google or Microsoft, and select your organisation. In OpenAI Codex or any other MCP client, add https://mcp.lightbringer.com/mcp as a remote MCP server with OAuth.
3. Confirm the connection by asking who you are on Lightbringer.
4. Describe the invention or paste your technical notes. ChatGPT creates the invention disclosure against your template, then checks it against patent review criteria for missing detail, unclear passages and an undefined technical problem.
5. Submit the disclosure for attorney review. Write actions are confirmed with you first.
6. Read attorney comments and redlines, answer questions and approve changes from ChatGPT. Lightbringer's registered patent attorneys draft and file the application.

One difference matters on ChatGPT specifically. On Free, Plus and Pro plans, conversations train OpenAI's models by default; switch off Improve the model for everyone in Data Controls, use a Temporary Chat, or use a Team or Enterprise workspace before discussing an unfiled invention. Business plans and the API do not train on your data by default. Setup details: Lightbringer MCP.
