(a) the use by a person of his own name or address,

(b) the use of indications concerning the kind, quality, quantity, intended purpose, value, geographical origin, the time of production of goods or of rendering of services, or other characteristics of goods or services, or

(c) the use of the trade mark where it is necessary to indicate the intended purpose of a product or service (in particular, as accessories or spare parts),

provided the use is in accordance with honest practices in industrial or commercial matters.

(3) A registered trade mark is not infringed by the use in the course of trade in a particular locality of an earlier right which applies only in that locality.

For this purpose an “earlier right” means an unregistered trade mark or other sign continuously used in relation to goods or services by a person or a predecessor in title of his from a date prior to whichever is the earlier of—
