Under the Lanham Act, any party who may be damaged by the actual or proposed registration of a mark is entitled to challenge the registration. If the mark has been published for proposed registration on the Principal Register, the party—usually the owner of a competing mark—can oppose the registration. The opposition must be in writing and be filed within 30 days of the proposed mark's publication in the Official Gazette. The U.S. Patent and Trademark Office (USPTO) may grant extensions of the 30-day period upon written request.
Under rules promulgated by the Madrid Protocol, if a party wants to oppose a trademark registration, the period for filing an opposition cannot be extended more than 180 days from the date the application was published. Those extensions must be now requested in one of two ways. A party opposing registration can, after the first 30-day period, either:
A party who intends to oppose a Section 1 or Section 44 trademark application can do so electronically or on paper. An opposition to a Section 66 application (an application under the Madrid Protocol) must be filed electronically.
If the mark has already been placed on the Principal Register, the party may petition the USPTO for cancellation of the registration. (15 United States Code, Section 1064.) A cancellation petition may be filed:
Marks proposed for placement on the Supplemental Register are not published for opposition. If a party believes that a mark's placement on the Supplemental Register may cause it harm, the party may file an application with the USPTO to have the registration cancelled. (15 United States Code, Section 1092.)
When a petition for opposition or cancellation is filed, or the USPTO declares an interference, an inter partes proceeding to resolve the dispute will be scheduled before the Trademark Trial and Appeal Board. (15 United States Code, Section 1067.) At the conclusion of this hearing, the Patent and Trademark Commissioner may:
The USPTO will cancel a mark on its own—without anyone asking for it—if the mark's owner fails to timely file a Section 8 Declaration showing that the mark is still in use. Because this form must be filed between the fifth and sixth year following the initial registration, and because the USPTO doesn't send a reminder, the registrations of many marks are cancelled for this reason. And because the USPTO also doesn't send notice of the cancellation, many trademark owners continue to use their marks in the belief that they are registered, when they're not.
The fact that a mark's registration is cancelled in no way affects the right of the mark's owner to challenge other users of the mark on the basis of first use. But as long as the mark remains unregistered, the owner will not be entitled to the benefits of registration should a trademark infringement suit become necessary.
