(d) Verified statement that trademark is used in commerce
(1) Within six months after the date on which the notice of allowance with respect to a mark is issued under section 1063(b)(2) of this title to an applicant under subsection (b) of this section, the applicant shall file in the Patent and Trademark Office, together with such number of specimens or facsimiles of the mark as used in commerce as may be required by the Director and payment of the prescribed fee, a verified statement that the mark is in use in commerce and specifying the date of the applicant’s first use of the mark in commerce and those goods or services specified in the notice of allowance on or in connection with which the mark is used in commerce.

Such examination may include an examination of the factors set forth in subsections (a) through (e) of section 1052 of this title.

(4) The failure to timely file a verified statement of use under paragraph (1) or an extension request under paragraph (2) shall result in abandonment of the application, unless it can be shown to the satisfaction of the Director that the delay in responding was unintentional, in which case the time for filing may be extended, but for a period not to exceed the period specified in paragraphs (1) and (2) for filing a statement of use.
