Section 14
SEC. 14. Voluntary surrender, cancellation, amendment and disclaimer after registration.—At any time, upon application of the registrant and payment of the required fee, the Director may permit any registration to be surrendered, cancelled, or for good cause shown to be amended, and he may permit any registered mark or trade-name to be disclaimed in whole or in part: Provided, That the registration when so amended shall still contain registrable matter and the mark or trade-name as amended shall still be registrable as a whole, and that such amendment or disclaimer does not involve such changes in the registration as to alter materially the character of the mark or trade-name. The Director shall make appropriate entry upon the records of the Patent Office and upon the certificate of registration or, if said certificate is lost or destroyed, upon a certified copy thereof. The Director in his discretion and upon payment of the required fee, may issue a substitute certificate limited to the term of the original certificate and incorporating such amendment or correction.
