What are the means of making an international application in order to enjoy trademark protectionİnTurkey? 

Basically, there are two ways of applying for a trademark protection in Turkey:
Direct application to Turkish Patent and Trademark Office: The first way of making a trademark registration application is to file an application directly to Turkish Patent and Trademark Office.

International Applications through the Madrid System: The second alternative for making a trademark application in Turkey is to use the Madrid System which is administered by World Intellectual Property Organisation (WIPO). Madrid System is formed by two treaties complementing each other.

These treaties are the Madrid Agreement and the Madrid Protocol. Turkey is only a member of the Protocol. Therefore, it accepts applications from only the States which are party to the Protocol or from the States which are party to both the Agreement and the Protocol. In both cases, the governing treaty for the international applications filed to Turkish Patent and Trademark Office is the Madrid Protocol.
