Patents and Trademarks: Patent Searching in Databases

Information on finding patents and US trademarks

Patents in USC Licensed Databases

Many of the databases that are licensed by the USC Libraries provide patent citations, patent results, or links directly to patents.

Limiting to patents is not straightforward in every database. Please read the description below each link for more information.

Google Patents coverage includes:

  • United States (1790-present)
