(a) Issuance and form
Certificates of registration of marks registered upon the principal register shall be issued in the name of the United States of America, under the seal of the Patent and Trademark Office, and shall be signed by the Commissioner or have his signature placed thereon, and a record thereof shall be kept in the Patent and Trademark Office. The registration shall reproduce the mark, and state that the mark is registered on the principal register under this chapter, the date of the first use of the mark, the date of the first use of the mark in commerce, the particular goods or services for which it is registered, the number and date of the registration, the term thereof, the date on which the application for registration was received in the Patent and Trademark Office, and any conditions and limitations that may be imposed in the registration.
(b) Certificate as prima facie evidence
A certificate of registration of a mark upon the principal register provided by this chapter shall be prima facie evidence of the validity of the registered mark and of the registration of the mark, of the registrant's ownership of the mark, and of the registrant's exclusive right to use the registered mark in commerce on or in connection with the goods or services specified in the certificate, subject to any conditions or limitations stated in the certificate.
(c) Application to register mark considered constructive use
Contingent on the registration of a mark on the principal register provided by this chapter, the filing of the application to register such mark shall constitute constructive use of the mark, conferring a right of priority, nationwide in effect, on or in connection with the goods or services specified in the registration against any other person except for a person whose mark has not been abandoned and who, prior to such filing -
(1) has used the mark;
(2) has filed an application to register the mark which is pending or has resulted in registration of the mark; or
(3) has filed a foreign application to register the mark on the basis of which he or she has acquired a right of priority, and timely files an application under section 1126(d) of this title to register the mark which is pending or has resulted in registration of the mark.
(d) Issuance to assignee
A certificate of registration of a mark may be issued to the assignee of the applicant, but the assignment must first be recorded in the Patent and Trademark Office. In case of change of ownership the Commissioner shall, at the request of the owner and upon a proper showing and the payment of the prescribed fee, issue to such assignee a new certificate of registration of the said mark in the name of such assignee, and for the unexpired part of the original period.
(e) Surrender, cancellation, or amendment by registrant
Upon application of the registrant the Commissioner may permit any registration to be surrendered for cancellation, and upon cancellation appropriate entry shall be made in the records of the Patent and Trademark Office. Upon application of the registrant and payment of the prescribed fee, the Commissioner for good cause may permit any registration to be amended or to be disclaimed in part: Provided, That the amendment or disclaimer does not alter materially the character of the mark. Appropriate entry shall be made in the records of the Patent and Trademark Office and upon the certificate of registration or, if said certificate is lost or destroyed, upon a certified copy thereof.
(f) Copies of Patent and Trademark Office records as evidence
Copies of any records, books, papers, or drawings belonging to the Patent and Trademark Office relating to marks, and copies of registrations, when authenticated by the seal of the Patent and Trademark Office and certified by the Commissioner, or in his name by an employee of the Office duly designated by the Commissioner, shall be evidence in all cases wherein the originals would be evidence; and any person making application therefor and paying the prescribed fee shall have such copies.
(g) Correction of Patent and Trademark Office mistake
Whenever a material mistake in a registration, incurred through the fault of the Patent and Trademark Office, is clearly disclosed by the records of the Office a certificate stating the fact and nature of such mistake, shall be issued without charge and recorded and a printed copy thereof shall be attached to each printed copy of the registration certificate and such corrected registration shall thereafter have the same effect as if the same had been originally issued in such corrected form, or in the discretion of the Commissioner a new certificate of registration may be issued without charge. All certificates of correction heretofore issued in accordance with the rules of the Patent and Trademark Office and the registrations to which they are attached shall have the same force and effect as if such certificates and their issue had been specifically authorized by statute.
(h) Correction of applicant's mistake
Whenever a mistake has been made in a registration and a showing has been made that such mistake occurred in good faith through the fault of the applicant, the Commissioner is authorized to issue a certificate of correction or, in his discretion, a new certificate upon the payment of the prescribed fee: Provided, That the correction does not involve such changes in the registration as to require republication of the mark.
