Welcome to PatentStorm

PatentStorm offers patents from the US Patent Office, including full-text patent search. Whether you are an inventor, a patent attorney, a patent agent or just curious about how things work, this site is for you.

Today, we have all patents from January 1990 forward. Soon, we will provide the most comprehensive source of free patent information on the web.

While you're here, be sure to check out our Patent Resources, which we hope to grow into the most useful and interesting collection of patent links and other patent information available anywhere. We plan to offer advanced search systems for all US patents as well.
