How can I check the status of my patent application?

You can check the status of your patent application through several methods:

• Patent Center: This platform provides information on issued patents, published patent applications, and applications claiming domestic benefit.
• Private PAIR (Patent Application Information Retrieval): For unpublished applications, applicants or their registered representatives can securely track progress. Note that a Customer Number must be associated with the application for access.
• Application Assistance Unit (AAU): For general inquiries, you can contact the AAU directly.

As stated in the MPEP: Status information relating to patent applications is available through Patent Center and the Patent Application Information Retrieval (PAIR) system. (MPEP 203.08)

For most up-to-date information, the MPEP recommends: Applicants and other persons seeking status information regarding an application should check Patent Center on the Office website at www.uspto.gov/patents/apply/patent-center.
