801.02(a) Act of 1946, Principal Register
The primary provision for registration in the Trademark Act of 1946 is for registration on the Principal Register (15 U.S.C. §§1051–1072). When a mark has been registered on the Principal Register, the mark is entitled to all the rights provided by the Act. The advantages of owning a registration on the Principal Register include the following:
- Constructive notice to the public of the registrant’s claim of ownership of the mark (15 U.S.C. §1072);
- A legal presumption of the registrant’s ownership of the mark and the registrant’s exclusive right to use the mark in commerce on or in connection with the goods/services listed in the registration (15 U.S.C. §§1057(b), 1115(a) );
- A date of constructive use of the mark as of the filing date of the application (15 U.S.C. §1057(c); TMEP §201.02);
- The ability to bring an action concerning the mark in federal court (15 U.S.C. §1121);
- The ability to file the United States registration with the United States Customs Service to prevent importation of infringing foreign goods (15 U.S.C. §1124);
- The registrant’s exclusive right to use a mark in commerce on or in connection with the goods or services covered by the registration can become "incontestable," subject to certain statutory defenses (15 U.S.C. §§1065, 1115(b) ); and
- The use of the United States registration as a basis to obtain registration in foreign countries.
If the applicant does not specify a register, the United States Patent and Trademark Office ("USPTO") will presume that the applicant seeks registration on the Principal Register.
