Subchapters I and II
The provisions of Subchapter I set forth the right of trademark owners to attain a federal registration of their marks. Subchapter I sets forth the requirements that a mark must meet to receive a registration on the Principal Register, which bestows various rights on the trademark owner to prevent others from infringing their mark. Among the requirements are prohibitions against the registration of marks that are confusingly similar to existing marks, are generic or merely descriptive, are scandalous or immoral, or fall onto certain other prohibited categories. Subchapter I also sets forth certain procedural requirements, such as the submission of an affidavit of continued use after five years of registration.
Subchapter II sets forth a form of registration on the Supplemental Register, for certain marks that are unregistrable under Subchapter I, but may become registrable in the future, such as those that are merely descriptive. This form of registration, while not granting all the protections of registration on the Principal Register, does provide notice to potential infringers that the mark is in use, and also provides some procedural benefits.
