IP for founders who would rather be building.
Lightbringer is an IP platform with its own registered patent attorneys. Work out what’s worth protecting before you raise, launch, or open-source, inside Claude and ChatGPT. It is free to start, and our attorneys step in when something is worth filing.
Free to start. Nothing is saved until you approve it. How your data is handled · Start in the web app
- Reading your deck and product notes
- Listing what looks new
- Checking what’s already captured
Two things look worth capturing, and neither is filed yet. One shows up in your demo next month.
- NewAdaptive cooling schedule. Drafted as an invention.
- NewBattery health model. Two questions open.
- TimingCapture it before the demo. Publishing first can make a patent harder to get.
This is a first look, not legal advice.
Used by more than 200 deep tech companies across the US and EU.



A plain checklist for the raise.
Most of the answers start with writing down what you’ve built and who built it. Start now, and decide later.
You own what you built
Founders, employees, and contractors have assigned their inventions.
You know what’s protected
Filed, pending, and captured, in one view.
You know what you keep secret
Recorded on purpose, not by accident.
You have a plan
An IP strategy that matches the roadmap.
Better found by you than by the investor’s lawyers.
From first idea to first filing.
You don’t need an attorney to capture and decide. You need one to file, and ours start from what you’ve already captured.
Connect your assistant. Capture what you’ve built so far and save a first IP strategy.
Capture new inventions, decide patent or secret, and keep the reasoning for the raise.
File the first patent with our attorneys, from the context you already built.
Nothing is saved, shared, or filed without your approval.

Founder questions
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.
Usually not. The easiest time to write down what you built is while you build it. Capturing an invention does not mean filing it: you decide later, with the reasoning on file. What matters early is that everyone who built it has assigned it to the company.
Lightbringer is free to start, and you buy credits when you need more. Filing a patent is part of Managed IP, with plans that include the platform. You decide if and when to file.
Not to start. You can capture inventions, decide what to protect, and draft a strategy on your own. When something is worth filing, a patent attorney makes the legal calls, through Managed IP or the counsel you already use.
