The scope of trademark protection
Trademark right of protection in general gives the exclusive right to use the mark for profit. In other words exclusivity granted by a trademark prohibits others from using in business trademark identical or similar for identical or similar goods / services. To sum up, the scope of trademark rights is determined by the specific goods or services associated with the mark and the geographic territory of its use/registration.
Exceptions are renowned trademarks (trademarks with a reputation), having additional privileges in many countries. Protection of these marks is extended over other goods/services than the one for which the trade mark was originally registered. This is because it is assumed that another entrepreneur could profit considerably from the reputation of a well-known trade mark.
