Where should the service of prior art or Section 301 written statements be addressed?

When serving prior art or Section 301 written statements on a patent owner, the service should be addressed to the correspondence address as specified in the patent regulations. The MPEP states:

“The service to the patent owner should be addressed to the correspondence address as set forth in 37 CFR 1.33(c).”

This means that the service should be sent to the official correspondence address on record for the patent. For more information on the correspondence address, the MPEP directs readers to MPEP § 2222.
