How can I access patent application status information?

Patent application status information is available through two main systems:

1. Patent Center: Provides information on issued patents, published patent applications, and applications to which a patented or published application claims domestic priority.
2. Private Patent Application Information Retrieval (PAIR): Allows secure tracking of unpublished patent applications for applicants or registered practitioners with power of attorney.

To access Private PAIR, you must associate a Customer Number with your application. As stated in the MPEP: Private PAIR makes available information relating to unpublished patent applications, but the applicant must associate a Customer Number with the application to obtain access.

For more information on Customer Number practice, refer to MPEP § 403.
