Requesting proof of trademark use
A proof-of-use request in trademark opposition is distinct from a standalone non-use cancellation.
Türkiye: practical decision and evidence
A proof-of-use request in trademark opposition is distinct from a standalone non-use cancellation. Check the opponent’s registration age, relevant goods/services and procedural conditions. Submit the request and response within the official timetable, using evidence tied to the relevant period.
Worked file: the opponent’s registration is old enough to raise use questions, but its evidence concerns different goods and years. Link the request to the specific procedural conditions and relevant period. Review evidence by goods and territory rather than equating any historic advertisement with legally sufficient use.
Evidence of genuine trademark use
Collect genuine-use evidence showing time, territory, goods/services and commercial use of the mark. Link invoices, packaging, advertising and sales records to the relevant period. An isolated screenshot without context may not establish the claimed use.
Five-year trademark use requirement
Turkish trademark use must be serious use for the registered goods or services in Türkiye. Preserve dated sales, packaging and advertising evidence. Five years of unjustified non-use can expose the registration to cancellation; an unused certificate is not sufficient proof of continuing protection.
Opposition arguments and evidence
An opposition needs the application number, legal grounds, reasoned arguments and indexed evidence. Verify the official filing procedure, payment and receipt before the deadline. Sending documents to a consultant or by ordinary email is not necessarily a valid official opposition.
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.
