Regulation 60

Any person, other than the registered proprietor, claiming to have an interest in a registered trade mark which is the subject of an application under rule 57 may apply to the Registrar in writing for permission to intervene.

The Registrar may, after hearing the parties concerned if he so required, refuse permission to intervene, or grant leave to intervene upon such terms (including any undertaking as to costs) as he thinks fit.

Any person granted permission to intervene shall, subject to the terms and conditions imposed in respect of the intervention, be treated as a party to the proceedings in question.
