1. Opposition:
The relevant legislation for opposition of trademark is Section IV of the Trademark Act 2011.
 Any person can file an opposition to registration of a trademark with the Registrar Office within three month from the day following the date of publication of registration (Article 48)
 The facts and grounds must be stated and any attachments shall be enclosed with the filed opposition.
 Once the opposition is filed and sent to the Registrar Office, the proprietor of the opposed trademark will be served a copy and may submit a statement of defense. The Registrar Office shall then serve a copy of the statement to the opponent who may submit an opinion on said statement. However, if the statement or opinion is likely to delay the proceedings, or where the facts and evidence are sufficiently clear, the Registrar Office may conduct opposition proceedings directly.
 The opposition shall be examined by an examiner who didn’t participate in the examination of the application for registration of the opposed trademark (Article 51)
 If the opposition is sustained, the registration of the trademark shall be cancelled (Article 54)

 lack of use of the mark
 failure to attach appropriate distinctive symbols under Article 43

 a mark that is likely to lead the public into misidentification or misconception in respect of the characteristics, quality, or place of origin of the merchandise
 A copy of the revocation will be served to the proprietor of a registered trademark by the Registrar Office who may submit a defense statement. The Registrar Office shall then serve a copy of the statement to the opponent who may submit an opinion on said statement. A request for revocation may be dismissed directly if it is lacking evidence and concrete facts or based on obviously groundless claims.
