Act 17 Trademarks Act 2010 (2) The registrar shall not, in exercise of any power conferred on him or her, under this section make any amendment to the register that would have the effect of adding goods or services or classes of goods or services to those in respect of which a trademark is registered whether in one or more classes immediately before the amendment is to be made or of ante-dating the registration of a trademark in respect of any goods or services. (3) This subsection shall not have effect in relation to goods or services as to which the registrar is satisfied that compliance with this subsection in relation to the goods or services would involve undue complexity and that the addition or ante-dating, as the case may be, would not affect any substantial quantity of goods or services and would not substantially prejudice the rights of any person. (4) A proposal for amendment of the register for the purpose referred to in subsection (1)— (a) shall be notified to the registered owner of the trademark affected; (b) shall be advertised with any modifications; (c) may be objected to before the registrar by a person aggrieved on the ground that the proposed amendment contravenes subsection (2). (5) A person aggrieved by the decision of the registrar under this section may appeal to the court. 93. Recognition of agents. Where under this Act an act is to be done by or to a person in connection with a trademark or proposed trademark or a procedure relating to the trademark, the act may under and in accordance with the regulations, be done by or to an agent of that person duly authorised in the prescribed manner. 69
