Protection Term and Payment Obligation

Patents are protected for 20 years from the filing date in Turkey. However, annuities (i.e., annual fees, maintenance, or renewal fees) must be paid each year to maintain the right.

Payment Deadlines

• The 3rd-year fee is due on the 2nd anniversary of the filing date.

• Subsequent annuities are due on the same day each year.

• If not paid on time, a 6-month grace period applies with a surcharge.

Failure to Pay

If the annuity is not paid within the grace period, the patent expires. A compensatory fee may allow revalidation within 2 months of the notification of lapse, but third-party rights during the lapse are preserved.

Applicable Fee Schedule

Annuities must be paid in the year they become due, based on the official fee schedule published for that year. Early payment according to previous years’ schedules is not accepted.

For clients who prefer a fully automated and self-service option, patent annuity payments may be completed online through our renewal platform, IPriver.

Alternatively, Aksoy IP continues to assist clients who prefer to handle renewals through direct email instructions and bank transfers, particularly in cases involving internal approval processes, accounting requirements, or portfolio-level coordination.
