(1) Subject to Division 2, the Registrar may, at the written request of the registered owner of a registered trade mark—
(a) amend the representation of the trade mark as entered in the Register if the amendment does not substantially affect the identity of the trade mark as at the time when the notice of the acceptance of the application for the registration of the trade mark was published under section 18;
(b) amend any particulars entered in the Register relating to any goods or services in respect of which the trade mark is registered if the amendment does not have the effect of extending the rights that apart from the amendment the owner has under the registration; or
(c) amend, or enter in the Register, any other particular in respect of the trademark if the amendment or entry does not have the effect of extending the rights that, apart from the amendment or entry, the owner has under the registration.
(2) An appeal lies to the High Court from a decision of the Registrar under subsection (1).
