Principal Register

In United States trademark law, the Principal Register is the primary register of trademarks maintained by the United States Patent and Trademark Office. It is governed by Subchapter I of the Lanham Act.Having a mark registered under the Principal Register confers certain benefits on the holder of the mark. Among them are:Nationwide constructive use and constructive notice, which cuts off rights of other users for similar marksThe possibility of achieving incontestable status after five years (which cuts off certain defenses of potential infringement defendants)The right to bring a federal cause of action for infringement without regard to diversity or amount in controversyThe right to request U.S. Customs and Border Protection officials to bar importation of goods bearing infringing trademarksProvisions for treble damages, attorney fees, and various other remedies.
