Find Patents

This guide is an overview of how to find patents using free, public, and UC Library resources.

Patent Families

Patent families are a collection of patent applications related by shared priority claims. They can include international applications. 

Legal Status

Patents are living documents. As such, they often change ownership, status, and coverage depending upon what happens to them. Legal status is important to check for any patent if you are concerned about their current status.
