Individual letters as trademarks – protection with restrictions
In principle, individual letters can be registered and protected as trademarks. However, the scope of protection for such "one-letter marks" is often limited in practice. This article provides a comprehensive overview of the current legal situation. We will also examine the differences between various types of trademarks and the responsible offices.
Eligibility for Registration of Single Letters
Individual letters are eligible for registration as trademarks under both German and European trademark law. A key prerequisite is that they possess sufficient distinctive character and are not purely descriptive. The Federal Court of Justice clarified as early as 2000 that individual letters are generally eligible as trademarks.
Limited Scope of Protection for One-Letter Marks
In practice, the scope of protection for one-letter trademarks is frequently interpreted very narrowly. This leads to specific considerations:
- Courts and trademark offices meticulously examine the specific graphic design when assessing the likelihood of confusion.
- Even if two marks use the same letter, a likelihood of confusion can be denied if their overall visual appearance differs significantly.
- In 2010, the ECJ ruled that individual letters are not inherently unprotectable. However, it must be determined in each individual case how the relevant public perceives the mark (judgment of 09.09.2010, C-265/09 P – α).
- More recently, in 2022, the European Court of First Instance emphasized that even slight differences in the design of individual letters can be sufficient to preclude a likelihood of confusion. This was highlighted in a case concerning two "K" marks (judgment of 09.11.2022, T-610/21).
Distinction Between Word Marks and Word/Figurative Marks
Word Marks
Word marks consist exclusively of words, letters, numbers, or other characters without any graphic design. The protection of a word mark generally extends to all customary forms of reproduction, including various fonts and capitalization. This broad protection applies irrespective of specific visual elements.
Word/Figurative Marks
Word/figurative marks, conversely, combine textual elements with distinct graphic design elements. They often offer an advantage, as they can be registrable even when a pure word mark might be rejected. This can occur with descriptive terms or terms that need to be kept free for general use. However, their scope of protection is typically limited to the specific graphic design presented in the application.
DPMA vs. EUIPO: Differences in Trademark Registration
The German Patent and Trade Mark Office (DPMA) is responsible for registering national German trademarks. In contrast, the European Union Intellectual Property Office (EUIPO) administers EU trademarks, which provide protection across the entire European Union.
Application Procedure
- DPMA: The trademark is registered and published after an examination of absolute grounds for refusal. The opposition period commences only after publication.
- EUIPO: The EU trademark is registered only after the opposition period has expired, provided no opposition has been filed.
Costs
- DPMA: 300 euros (290 euros for electronic filing) for up to three classes. Each additional class costs 100 euros.
- EUIPO: 850 euros for one class for online filing, 50 euros for the second class, and 150 euros per class from the third class onwards.
Scope of Protection
- DPMA: Protection is limited to Germany only.
- EUIPO: Provides uniform protection across all EU member states.
Single-Image Marks at DPMA and EUIPO
When it comes to single-image marks, which are purely figurative marks without word elements, there are no significant differences in the application procedure between the DPMA and the EUIPO. Both offices examine single-image marks for absolute grounds for refusal and distinctiveness. The requirements for graphic representability and the assessment of protectability are largely identical in both jurisdictions.
As with other trademark forms, the primary distinction lies in the territorial scope of protection, along with the associated costs and procedural specifics. A single-image mark filed with the DPMA is protected solely in Germany, while an EUIPO-registered single-image mark receives protection throughout the entire EU.
Conclusion
Choosing between a national trademark and a European Union trademark, as well as between different trademark forms, depends on several factors. These include the planned area of use, the available budget, and the distinctive character of the sign. For single letters and single-image marks, it is crucial to ensure a characteristic design to maximize the scope of protection.
Overall, trademark offices and courts carefully scrutinize one-letter trademarks and single-image trademarks. They strive for a fair balance between trademark protection and the necessity to keep certain elements free for general use. Careful planning and professional legal advice can help you achieve optimal protection for your trademark, regardless of whether the application is filed with the DPMA or EUIPO.
