The assessment of bad faith under Turkish law has developed through legislation and case law, with the circumstances of each application playing a central role.

In their article “Evaluation of Bad Faith in Trademark Applications Under Turkish Trademark Law,” published in The Trademark Reporter (TMR), our Partner Uğur Aktekin, Senior Associate Selin Bilik Erdönmez and Associate Bilge Ayperi Kemer examine the definition and legal nature of bad faith under Turkish trademark law, its typical appearances in trademark practice, and the judicial and procedural principles applied in determining bad faith. The article also addresses the consequences of a finding of bad faith and provides a comparative analysis from the perspective of EU law and Common Practice No. CP13.
