Can the owner of a well-known trade mark stop the use of a similar mark in relation to unrelated goods and/or services?

A trade mark with a reputation may be protected from unauthorised use in relation to non-competing goods and/or services. They are protected in case the use of a later trade mark without due cause would take unfair advantage of, or be detrimental to, the distinctive character or the repute of the earlier trade mark.

How do I know if a trade mark proposed for registration is already being used by another undertaking? Why should I perform a trade mark search?

Trade mark searches are extremely important and typically designed to determine whether a particular trade mark is available for use on a relevant territory. Trade mark search is an investigation to discover potential conflicts between a proposed mark and the existing ones. Searches help to determine if you can register your trade mark on a relevant territory. The search may identify trade marks that are visually, phonetically, or conceptually the same or similar to the trade mark to be adopted and that cover the same or similar goods or services.
