Patentee May Alert Examiner to Interfering Claims
Note:
A patentee can inform an examiner about interfering claims in an application, but must not suggest an interference unless they become the applicant by filing a reissue application.

A patentee may not suggest an interference unless it becomes an applicant by filing a reissue application. A patentee may, however, to the limited extent permitted under 37 CFR 1.291, alert an examiner to the existence of interfering claims in an application. See MPEP §§ 1134 and 1901.
