There are two ways in which a mark can be objected to;
Third party observations
At any point after the trademark application has been accepted and published an application for registration, and before it is actually registered, anyone can make ‘third party observations’.
You can tell the UKIPO if you think that we accepted the application in error, bringing to our attention any relevant facts of which we may not have been aware at the time we accepted the application.
Making a third party observation is not a formal legal action, and the UKIPO are not bound to act on them. They may, however, rely on evidence given in an observation to support any later objection to the application.
Alternatively, if you wish to formally raise legal objections to the trade mark application you can oppose the application. Opposition is the legal procedure that allows you to try to stop a published mark going on to become registered.
You can oppose the entire application, or only some of the goods or services it covers.
