Information on finding patents and US trademarks

USC Quick Links


This guide has been created to help in the understanding and searching for patents in the United States and across the globe.

First time? Start by reading the Families and Classifications tab to help familiarize yourself with the organization of patent and trademark data.

If you are searching for a patent by topic or category (with no specific country in mind), it is recommended to start with Patent Searching in Databases tab above.

If you are searching for a patent by a specific country or you have patent number (i.e. US xxxxxxx, WO xxxxxxx, EU xxxxxx), then go directly to the United States or Other Countries tab above.

For more information on filing patent of USC conducted research, please contact the USC Stevens Center for Innovation.
