the Registrar may, after hearing the applicant if he so desires, withdraw the acceptance and proceed as if the application had not been accepted.
The Registrar may in his discretion cause the application to be advertised again or, in any case falling under clause (b) may, instead of causing the application to be advertised again, notify in the prescribed manner the correction or amendment made in the application.
Any person may, within three months from the date of the advertisement or re-advertisement of an application for registration or within such further period, not exceeding one month in the aggregate, as the Registrar, on application made to him in the prescribed manner and on payment of the prescribed fee, allows, give notice in writing in the prescribed manner to the Registrar, of opposition to the registration.
the Registrar shall, unless the Central Government otherwise directs, register the said trade mark in Part A or Part B of the register, as the case may be, and the trade mark when registered shall be registered as of the date of the making of the said application and that date shall, subject to the provisions of section 131, be deemed to be the date of registration.
those persons may be registered as joint proprietors of the trade mark, and this Act shall have effect in relation to any rights to the use of the trade mark vested in those persons as if those rights had been vested in a single person.
