Opposing Party Must Be Notified of Communications Regarding Interference
Note:
Parties in an interference must be informed and allowed to participate in communications or actions related to the involved patents or applications.

Since an interference involves two or more parties, the integrity of the process requires the opportunity for the opposing party to participate in communications or actions regarding any involved application or patent. Once an interference is declared, any attempt by a party to communicate with the Board through the examiner or to have the examiner act in an involved patent or application without Board authorization should be promptly reported to the Board. Board action may include a sanction in the interference or referral of a patent practitioner to the Office of Enrollment and Discipline.
