Section 1051, prior to the accepted filing of a “Statement of Use” and issuance of a “Certificate of Registration” pursuant to Section 1(d) of the Lanham Act or an accepted filing of an “Amendment to Allege Use” whereby such intent-to-use Trademark application is converted to a “use in commerce” application pursuant to Section 1(c) of the Lanham Act.
