But are the marks merely descriptive of the underlying goods? A mark that merely describes the goods in connection with which it is being used cannot be registered on the USPTO's Principal Register without a showing of acquired distinctiveness. TMEP 1209; 15 USC 1052(e)(1). A mark is merely descriptive " if it describes an ingredient, quality, characteristic, function, feature, purpose, or use of the specified goods or services." TMEP 1209.01(b). However, if a mark is deemed merely descriptive, it can be registered upon proof of "acquired distinctiveness," which means the mark has become distinctive as applied to the applicant's goods in commerce (i.e., consumers associate the mark with the applicant's goods, rather than only as a descriptive term). TMEP 1212; 15 USC 1052(f).

Or do the terms "require imagination, thought, or perception to reach a conclusion as to the nature of those goods..." in which case the mark would be suggestive and registerable on the Principal Register without a showing of acquired distinctiveness. TMEP 1209.01(a).
