Patent: twenty-year term
The Turkish patent term is twenty years from filing, subject to statutory maintenance requirements.
Türkiye: practical decision and evidence
The Turkish patent term is twenty years from filing, subject to statutory maintenance requirements. Keep a filing-date and annual-fee calendar. An unpaid or expired right must not be presented as active merely because its document still exists.
Worked file: an old patent document is used in a sales presentation without checking annual fees. Build a filing-date calculation and obtain current register status. Record expiry, lapse or active maintenance separately; the presentation must describe the actual right rather than its historical existence.
Patent annual fees
Patent maintenance needs a calendar linked to filing dates and the applicable annual-fee year. Verify the current official tariff and payment record. Payment to an intermediary does not prove that the office received the correct fee for the correct patent.
Patent grant decision
A patent grant follows the competent office’s examination and required formal steps. Check the grant decision, approved claims, fee status and register entry. A search report, supplier promise or test result is not a patent grant.
Patent assignment and licensing
Separate patent assignment from a licence to exploit specified rights. Identify patent/application numbers, territories, exclusive/non-exclusive terms and register requirements. A licence agreement does not automatically make the licensee the patent owner.
Official filing and support
This guidance concerns Turkish rights unless a section expressly names another jurisdiction. Kayra can coordinate research, document preparation and follow-up. Registration, opposition and grant decisions belong to the competent office. Verify any required representative’s registration and authority before appointing them; court proceedings require appropriately qualified legal representation. The enquiry form requests consultancy, and does not itself file an official application.
