Turkey is a member of EPC and PCT and accepts validity of patents via both routes. After a PCT application, it is possible that this application can be prosecuted to the Turkish Patent Trademark Office (TURKPATENT) for national entry.
In other words, applications received via this route are treated as national patent applications. TURKPATENT, in this case, skips the search step and starts from examination step for such applications. National entry services involve filing, examination, grant, renewal, appeal services.
