(b) the goods having been put on the market under the registered trade mark by the proprietor or with his consent.
(4) Sub-section (3) shall not apply where there exists legitimate reasons for the proprietor to oppose further dealings in the goods in particular, where the condition of the goods, has been changed or impaired after they have been put on the market.
Registration to be prima facie evidence of validity. 31. (1) In all legal proceedings relating to a trade mark registered under this Act (including applications under section 57), the original registration of the trade mark and of all subsequent assignments and transmissions of the trade mark shall be prima facie evidence of the validity thereof;
(2) In all legal proceedings as aforesaid a registered trade mark shall not be held to be invalid on the ground that it was not a registrable trade mark under section 9 except upon evidence of distinctiveness and that such evidence was not submitted to the Registrar before registration, if it is proved that the trade mark had been so used by the registered proprietor or his predecessor in title as to have become distinctive at the date of registration.
Protection of registration on ground of distinctiveness in certain cases. 32. Where a trade mark is registered in breach of sub-section (1) of section 9, it shall not be declared invalid if, in consequence of the use which has been made of it, it has after registration and before commencement of any legal proceedings challenging the validity of such registration, acquired a distinctive character in relation to the goods or services for which it is registered.
Effect of acquiescence. 33. (1) Where the proprietor of an earlier trade mark has acquiesced for a continuous period of five years in the use of a registered trade mark, being aware of that use, he shall no longer be entitled on the basis of that earlier trade mark—
(a) to apply for a declaration that the registration of the later trade mark is invalid, or
(b) to oppose the use of the later trade mark in relation to the goods or services in relation to which it has been so used,
unless the registration of the later trade mark was not applied in good faith.
(2) Where sub-section (1) applies, the proprietor of the later trade mark is not entitled to oppose the use of the earlier trade mark, or as the case may be, the exploitation of the earlier right, notwithstanding that the earlier trade mark may no longer be invoked against his later trade mark.
Saving for vested rights. 34. Nothing in this Act shall entitle the proprietor or a registered user of registered trade mark to interfere with or restrain the use by any person of a trade mark identical with or nearly resembling it in relation to goods or services in relation to which that person or a predecessor in title of his has continuously used that trade mark from a date prior—
(a) to the use of the first-mentioned trade mark in relation to those goods or services be the proprietor or a predecessor in title of his; or
(b) to the date of registration of the first-mentioned trade mark in respect of those goods or services in the name of the proprietor of a predecessor in title of his;
whichever is the earlier, and the Registrar shall not refuse (on such use being proved) to register the second mentioned trade mark by reason only of the registration of the first-mentioned trade mark.
Saving for use of name, address or description of goods or services. 35. Nothing in this Act shall entitle the proprietor or a registered user of a registered trade mark to interfere with any bona fide use by a person of his own name or that of his place of business, or of the name, or of the name of the place of business, of any of his predecessors in business, or the use by any person of any bona fide description of the character or quality of his goods or services, services.
