Bad-faith trademark opposition
For bad faith, build a chronology of prior relations, access to the sign, earlier dealings and the disputed filing.
Türkiye: practical decision and evidence
For bad faith, build a chronology of prior relations, access to the sign, earlier dealings and the disputed filing. Explain what the evidence supports. Mere dislike of a competitor or similarity without context does not prove bad faith.
Worked file: a former distributor files the supplier’s mark after negotiations break down. Preserve dated agreements, correspondence, access to branding and the later application. Analyse what shows knowledge and intent, while separating inference from proved facts; similarity alone is not the entire bad-faith case.
Other earlier rights
Earlier rights can include names, trade names, copyright or relevant unregistered signs under the applicable ground. Preserve evidence showing entitlement and acquisition before the challenged filing. An unverified ownership assertion is not enough.
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.
Likelihood of confusion
Confusion is assessed through the signs, goods/services, relevant consumers and the overall impression. Prepare a comparison showing similarities and meaningful differences. A shared letter or a numerical similarity score alone does not establish the legal result.
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.
