The Trade and Merchandise Marks Act,1958
Section 30. Acts not constituting infringement
(1) Notwithstanding anything contained in this Act, the following acts do not constitute an infringement of the right to the use of a registered trade mark-
(a) Where a trade mark is registered subject to any conditions or limitations, the use of the trade mark in any manner in relation to goods to be sold or other-wise traded in, in any place, or in relation to goods to be exported to any market, or in any other circumstances, to which, having regard to those conditions or limitations, the registration does not extend:
(b) The use by a person of a trade mark in relation to goods connected in the course of trade with the proprietor or a registered user of the trade mark if, as to those goods or a bulk of which they form part, the registered proprietor or the registered user conforming to the permitted use has applied the trade mark and has not subsequently removed or obliterated it, or has at any time expressly or impliedly consented to the use of the trade mark;
(c) The use of a trade mark by a person in relation to goods adapted to form part of, or to be accessory to, other goods in relation to which the trade mark has been used without infringement of the right given by registration under this Act or might for the time being be so used, if the use of the trade mark is reasonably necessary in order to indicate that the goods are so adapted, and neither the purpose nor the effect of the use of the trade mark is to indicate, otherwise than in accordance with the fact, a connection in the course of trade between any person and the goods;
(d) The use of a registered trade mark, being one or two or more trade marks registered under this Act which are identical or nearly resemble each other, in exercise of the right to the use of that trade mark given by registration under this Act.
(2) Where the goods bearing a registered trade mark are lawfully acquired by a person, the sale of or other dealings in those goods by that person or by a person claiming under or through him is not an infringement of the trade mark by reason only of the trade mark having been assigned by the registered proprietor to some, other person after the acquisition of those goods.
