Welcome to PatentStorm

PatentStorm has a new look and new functionality.

PatentStorm offers full-text U.S. patents from the U.S. Patent Office, including advanced patent search capabilities and full image retrieval in handy PDF format. Whether you are an inventor, a patent attorney, a patent agent or just curious about how things work, this site is for you.

Our full-text patent database goes back to 1976, when the U.S. Patent Office began converting its patents to full text. Everything we offer is free.

PatentStorm is a sister company of Storming Media, a Washington, D.C.-based company that makes Pentagon information more accessible, and LegiStorm, which provides transparency to the operations of the U.S. Congress.
