IP courts resolved the dispute over the well-known name BEYONCE. After registration of her name by different Turkish companies, the famous singer and actress BEYONCE KNOWLES represented by Alimoğlu Oruç instituted actions for invalidation of these registrations. In their rulings, all IP Courts acknowledged the notoriety of the name of the singer. In their judgments, the Courts agreed that the mark BEYONCE was not well-known at the time the trademark applications have been filed, the name still gained notorious status and thus cannot be registered by any person other than BEYONCE KNOWLES. The arguments of the defendants that the actions should be refused because of remaining silent for long time was unanimously dismissed by the Courts with a view that a party which registered a trademark in bad faith cannot rely on loss of right for remaining silence.
