806.04 Deleting a Basis
If an applicant claims more than one basis, the applicant may delete a basis at any time, before or after publication. 37 C.F.R. §2.35(b)(1). No petition to the Director is required to delete a basis from a multiple-basis application after publication. When the applicant deletes a basis, the applicant must also delete the goods/services/classes covered solely by that basis. 37 C.F.R. §2.35(b)(7).
To expedite processing, the USPTO recommends that a request to delete a §1(b) basis from a multiple-basis application be filed through TEAS, at http://www.uspto.gov/trademarks/teas/post_publication.jsp.
