217 Relinquishment of Extension
If a potential opposer whose request for an extension of time to oppose is pending, or whose granted extension has not yet expired, files a letter notifying the Board that it will not oppose, the Board will immediately forward the application that was the subject of the request or extension for issuance of a registration certificate or notice of allowance, as appropriate.
If a potential opposer that has requested or obtained an extension of time to oppose has agreed unconditionally in writing not to oppose, applicant may submit a copy of the agreement to the Board, with an appropriate cover letter bearing proof of service upon potential opposer, and the Board will immediately forward the subject application for issuance of a registration certificate or notice of allowance, as appropriate. Cf. TBMP § 212.06 (Action by Board-After Consideration of Amendment by TMEO).
An ESTTA form for either situation described above involving relinquishment of an extension of time to oppose is available. Consequently, the filing must be made through ESTTA.
