Can I object to a trademark being granted?

As owner of an earlier registered trademark, you may oppose to the registration of a trademark that was filed on a later (priority) date if, amongst others:

• it is identical or similar with your earlier trademark and the goods or services for which registration is applied for are identical with the products or services for which your earlier trademark is registered;
• it is identical with or similar to your earlier trademark and the goods or services for which registration is applied for are identical with or similar to the goods or services for which your earlier trademark is registered, if there exists a likelihood of confusion on the part of the public on the territory in which your earlier trademark is registered; or
• it is identical with or similar to your earlier trademark with a reputation and where the use without due cause of the trademark applied for would take unfair advantage of, or be detrimental to, the distinctive character or the repute of your earlier trademark.
