§29 (15 U.S.C. §1111) Notice of registration; display with mark; recovery of profits and damages in infringement suit
Notwithstanding the provisions of section 1072 of this title, a registrant of a mark registered in the Patent and Trademark Office, may give notice that his mark is registered by displaying with the mark the words "Registered in U.S. Patent and Trademark Office" or "Reg. U.S. Pat. & Tm. Off." or the letter R enclosed within a circle, thus ®; and in any suit for infringement under this chapter by such a registrant failing to give such notice of registration, no profits and no damages shall be recovered under the provisions of this chapter unless the defendant had actual notice of the registration.
(Amended Oct. 9, 1962, 76 Stat. 773; Jan. 2, 1975, 88 Stat. 1949; Nov. 16, 1988, 102 Stat. 1343.)
*Note: The amendment of the wording of this term by Public Law 93-596 became effective on January 2, 1975. However, the amendment provides that any registrant may continue to give notice of his registration in accordance with §29 of the Trademark Act of 1946, as amended Oct. 9, 1962, as an alternative to notice in accordance with §29 of the Trademark Act as amended by Public Law 93-596, regardless of whether his mark was registered before or after January 2, 1975.
