2220 Certificate of Service

If the requester is a person other than the patent owner, the owner of the patent must be served with a copy of the request in its entirety. The service should be made to the correspondence address as indicated in 37 CFR 1.33(c). The third party requester must set forth on the certificate of service the name and address of the party served and the method of service. The certificate of service must be attached to the request submitted to the Office. Further, the copy of the request served on the patent owner must also include a copy of the certificate of service. >If service was not possible, a duplicate copy of the request papers must be supplied to the Office together with an explanation of what effort was made to effect service, and why that effort was not successful.<

The most recent address of the attorney or agent of record can be determined by checking the Office's register (roster) of patent attorneys and agents maintained by the Office of Enrollment and Discipline pursuant to 37 CFR 10.5 and 10.11(a). See MPEP § 2266.03 regarding service on the requester and on the patent owner.
