Disputes can arise during the trademark registration process. If this occurs or if you are opposing the registration of another mark and the dispute is handled by the United State Patent and Trademark Office (USPTO), then it is an inter partes proceeding. Such proceedings are handled by the Trademark Trial and Appeal Board (TTAB). The TTAB adheres to Federal Rules of Civil Procedure. These proceedings include filing opposition to a mark after it has been published in the Official Gazette. Parties have 30 days after publication to file such an opposition, although extension of time to file opposition can be requested. This can allow for negotiations with the other party and attempts to settle the dispute early and quickly. A party filing opposition must be by someone that believes they would be damaged if the mark were registered. Grounds for opposition can include dilution, likelihood of confusion, genericness, descriptiveness, misdiscriptiveness, fraud, deceptiveness, lack of intent to use, and scandalous matter.
