PQAI – AI Powered Patent Search


PQAI is a free and open source tool that you can use to run prior-art searches in a simple way by just entering a plain English description of a technical idea. it will find the closest prior work from patents and research papers and show it to you in an easy to understand format.


It is better than traditional search tools because you can entire longer text, up to 100 words. It will return results based on comparing the abstracts of the prior art in the USPTO patent database. The search database is updated on a monthly basis.

If you want to include this search into your own tool then you also get an API for that. Please contact the manufacturer for this, they are mentioned on the website of that widget.
