Trademark
A secondary list of trademarks and service marks maintained by the u.s. patent and trademark office. the supplemental register provides limited trademark rights and benefits and consists of marks that do not qualify for the principal register, usually because they are nondistinctive and consumers do not associate these terms with a specific source. (in trademark terminology, they lack secondary meaning.) descriptive marks, surnames, and marks consisting primarily of geographical terms are commonly placed on the supplemental register. (see also: principal register)
