Similar Sign, Different Mark: Trademark Infringement Claim by GSM Operator Dismissed

Case Overview

A major Turkish mobile operator sued a small mobile accessories retailer whose shop sign allegedly resembled the operator's trademark in colour, background and wording. The defendant denied infringement and did not participate in the proceedings.

Expert and Court Analysis

• Holistic comparison: Two successive expert panels found the defendant's sign not similar to the plaintiff's marks visually, phonetically or conceptually; dominant elements differ.
• Average consumer test: In a mobile accessories retail setting, an average consumer would not confuse the two signs.
• Evidentiary gap: A photograph in the claim could not be dated or attributed to the defendant, limiting its probative weight.

Key Takeaway

Famous mark status does not make every similar-looking sign automatically infringing. SMK Article 29 requires an actual risk of consumer confusion assessed holistically across all verbal, figurative and colour elements. This decision is a significant precedent against overbroad infringement claims by well-known mark owners.

FAQ

Can similar colours or background alone establish trademark infringement in Turkey?

No. Colour similarity is one factor in the holistic comparison. Here, different dominant verbal and figurative elements outweighed any colour similarity.

Who is the relevant consumer in trademark confusion analysis?

An averagely informed, reasonably attentive consumer who cannot simultaneously compare both signs side by side — not an expert. The comparison is holistic and focused on dominant elements.
