(1) Where a trade mark consisting of an invented word or invented words has become so well known as respects any goods or services in respect of which it is registered and in relation to which it has been used that use thereof in relation to other goods or services would be likely to be taken as indicating a connection in the course of trade between those goods or services and a person entitled to use the trade mark between those goods or services and a person entitled to use the trade mark in relation to the first-mentioned goods or services, then, notwithstanding that the proprietor registered in respect of the first-mentioned goods or services does not use or propose to use the trade mark in relation to those other goods or services and notwithstanding anything in article 698, the trade mark may, on the application in the prescribed manner of the proprietor registered in respect of the first-mentioned goods or services, be registered in his or her name in respect of those other goods or services as a defensive trade mark and, while so registered, shall not be liable to be taken off the register in respect of those goods under article 698.
