Notwithstanding anything in Sees. 37 and 38, a trade mark shall not be assignable or transmissible in a case in which as a result of the assignment or transmission there would in the circumstances subsist, whether under this Act or any other law, an exclusive right in one of the persons concerned to the use of the trade mark limited to use in relation to goods to be sold, or otherwise traded in, in any place in India and an exclusive right in another of these persons to the use of trade mark nearly resembling the first-mentioned trade mark or of an identical trade mark in relation to the same goods or description of goods limited to use in relation to goods to be sold, or otherwise traded in, in any other place in India:
Provided that in any such case, on application in the prescribed manner by the proprietor of a trade mark who proposes to assign it, or by a person who claims that a registered trade mark has been transmitted to him or to a predecessor-in-title of his since the commencement of his Act, the Registrar, if he is satisfied that in all the circumstances the use of the trade mark in exercise of the said rights would not be contrary to the public interest, may approve the assignment or transmission, and an assignment or transmission so approved shall not, unless it is shown that the approval was obtained by fraud or misrepresentation, be deemed to be invalid under this section or Sec. 39 if application for the registration under Sec. 44 of the title of the person becoming entitled is made within six months from the date on which the approval is given or, in case of a transmission, was made before that date.
