Questions

Can ChatGPT or Claude write a patent?

They can help you describe an invention, but a patent is a legal document, and what to claim is a judgment call. With Lightbringer, your assistant captures the invention and the reasoning, and a registered patent attorney drafts and files from that record when you decide it’s worth it.

How do I add it?

Add Lightbringer from the Claude directory or the ChatGPT app directory, sign in with your organisation, and your records are available in the chat. In Claude Code, Codex, or Cursor, the setup page shows the steps.

Is it safe to put unfiled inventions into Claude or ChatGPT?

Lightbringer is built for unfiled inventions. Sign-in is per organisation, nothing is saved until you approve it, and nothing is filed without a person. Claude and ChatGPT keep their own data settings, so check yours before you share details you haven’t filed.

What does it cost?

It is free to start, and you buy credits when you need more. Drafting and filing are part of Managed IP, with plans that include the platform.
