Identify Two Distinctions Between Registration on the Two Registers of the USPTO

Question

Examlex · Accepted Answer

The Answer is While a registration on the Principal Register is prima facie (literally, "at first sight" or "on its face") evidence of the registrant's exclusive right to use of the mark, registration on the Supplemental Register has no such evidentiary effect. A registration on the Principal Register is constructive notice of a claim of ownership so as to eliminate a defense of good faith in an infringement suit, but a Supplemental Registration has no such effect. While a registration on the Principal Register may become incontestable after five years of registration, a Supplemental Registration may never achieve that status. Registration on the Supplemental Register cannot be used to stop importations of infringing or counterfeit goods into the United States. On the other hand, registration on the Supplemental Register does afford some protections: An action for infringement of the mark can be brought in federal court. The registration will be on file with the USPTO and can be cited by the USPTO against another's subsequent application to register a confusingly similar mark. The registration will be located through standard searches of USPTO records, thus possibly deterring others from using or applying for a similar mark. The registrant is entitled to use the registration symbol
