Question

Quizplus · Accepted Answer

Not all marks that are ineligible for the Principal Register can be registered on the Supplemental Register. The Supplemental Register is primarily for marks that are capable of distinguishing an applicant's goods or services but are not yet distinctive enough for the Principal Register, often because they are merely descriptive, not inherently distinctive, or have not acquired secondary meaning. Marks that are generic, deceptive, or violate other registration prohibitions cannot be registered on the Supplemental Register.
