Basically, there are three types of protection requested abroad. • Classical Patent It should be preferred in case the protection is kept with 2 or 3 countries. All applications are made for each country separately, and all patent processes (research, examination) are retried separately. • PCT (Patent Cooperation Treaty) If the protection will be requested in multiple countries, it should be preferred. With one and single application, the protection can be applied in all 146 member countries of the PCT. The PCT patent is not a license. The system on which research and examination steps are taken jointly. These joint research and examination reports will be effective when you transit to the countries which are the members of the PCT. • EPC (European Patent Convention) It should be preferred if the protection is requested only across Europe (38 countries). When research and examination studies are completed, if the patent fulfills the patent criteria, it will be licensed and the protection is initiated with the translation requested with the translation provided by the member countries of this system.
