  CHAPTER I--UNITED STATES PATENT AND TRADEMARK OFFICE, DEPARTMENT OF 
                                COMMERCE
 
PART 2_RULES OF PRACTICE IN TRADEMARK CASES--Table of Contents
 
Sec. 2.35  Adding, deleting, or substituting bases.

    (a) In an application under section 66(a) of the Act, an applicant 
may not add, substitute or delete a basis, unless the applicant meets 
the requirements for transformation under section 70(c) of the Act and 
Sec. 7.31 of this chapter.
    (b) In an application under section 1 or section 44 of the Act:
    (1) Before publication for opposition, an applicant may add or 
substitute a basis, if the applicant meets all requirements for the new 
basis, as stated in Sec. 2.34. The applicant may delete a basis at any 
time.
    (2) After publication, an applicant may add or substitute a basis in 
an application that is not the subject of an inter partes proceeding 
before the Trademark Trial and Appeal Board, but only with the express 
permission of the Director, after consideration on petition. 
Republication will be required. The amendment of an application that is 
the subject of an inter partes proceeding before the Board is governed 
by Sec. 2.133(a).
    (3) When an applicant substitutes one basis for another, the Office 
will presume that there was a continuing valid basis, unless there is 
contradictory evidence in the record, and the application will retain 
the original filing date, including a priority filing date under section 
44(d), if appropriate.
    (4) If an applicant properly claims a section 44(d) basis in 
addition to another basis, the applicant will retain the priority filing 
date under section 44(d) no matter which basis the applicant perfects.
    (5) The applicant may add or substitute a section 44(d) basis only 
within the six-month priority period following the filing date of the 
foreign application.
    (6) When the applicant adds or substitutes a basis, the applicant 
must list each basis, followed by the goods or services to which that 
basis applies.
    (7) When the applicant deletes a basis, the applicant must also 
delete any goods or services covered solely by the deleted basis.
    (8) Once an applicant claims a section 1(b) basis as to any or all 
of the goods or services, the applicant may not

amend the application to seek registration under section 1(a) of the Act 
for those goods or services unless the applicant files an allegation of 
use under section 1(c) or section 1(d) of the Act.
