###
Differences Between Trademark Registration on the Supplemental Register and the Principal Register:
- While a Principal Registration is prima facie evidence of the registrant’s exclusive right to use of the mark, a Supplemental Registration has no such evidentiary effect.
- While a Principal Registration is constructive notice of claim of ownership so as to eliminate a defense of good faith, a Supplemental Registration has no such effect.
- While a Principal Registration may become incontestable after five years of registration, a Supplemental Registration can never achieve that evidentiary status.
- While a Principal Registration can be used as a basis for the Department of the Treasury to stop importations of infringing products into the United States, a Supplemental Registration cannot.
- While a Principal Registration receives protection as a valid trademark in litigation, a Supplemental Registration will not, prima facie, receive protection as a valid trademark because its very presence on the Supplemental Register indicates a preliminary determination that the mark is not distinctive of the applicant’s goods.
