Trademark law
Not everyone immediately thinks of trademark law when they think of paper tissues or caffeinated cold drinks. And yet it plays an important role. After all, everyone probably has at least one brand name in mind when it comes to these products. Through the clever selection of their products and brands, the companies behind them have succeeded in making these names synonymous with an entire product category. We advise and represent you in all areas of trademark law.
You can find us at Kaiserstrasse 1a in Bonn, just a few minutes’ walk from the main train station. From there, we represent clients from the Rhineland and throughout Germany in trademark matters before the German Patent and Trademark Office as well as the European Union Intellectual Property Office. You decide whether we meet at our offices in Bonn or speak via video conference.

Frequently Asked Questions About Trademark Law
What is a trademark, and what types of trademarks are there?
A trademark is a legally protected symbol that identifies a company’s goods and services and distinguishes them from those of others. There are word marks (e.g., company names), figurative marks (logos), word/figurative marks (a combination of a name and a logo), sound marks, color marks, and three-dimensional marks.
Why should I register a trademark?
A registered trademark grants you the exclusive right to use it and protects you from third parties using the same or a similar name, logo, or symbol for similar goods or services. This strengthens your position in the market and safeguards your brand name as a valuable asset.
What is the process for filing a trademark application?
The trademark registration process consists of several steps: First, a trademark search is conducted to ensure that no similar trademarks exist. The trademark is then filed with the German Patent and Trademark Office (DPMA) or with EUIPO (for EU trademarks). After examination and payment of the fees, the trademark is registered if no objections are raised.
How long does trademark protection last?
A registered trademark is initially protected for ten years. Protection may be renewed as often as desired for additional periods of ten years, provided that the trademark is actively used and the renewal fees are paid on time.
How much does it cost to register a trademark?
The costs vary depending on the type and scope of the application. A German trademark application costs starting at approximately 300 euros for the first three classes with the DPMA. An EU trademark application is more expensive because it provides protection in all EU countries. In addition, there may be costs for professional consultation and trademark searches.
How do I check if my trademark already exists?
A trademark search is essential to determine whether identical or similar trademarks have already been registered. This can be done in the DPMA’s trademark register or through European and international trademark offices. An attorney can conduct a more comprehensive search to avoid potential conflicts.
What is trademark infringement, and what can I do if my trademark is infringed?
A trademark infringement occurs when a third party uses your trademark without permission for similar goods or services. You have the right to take action against such use—through cease-and-desist letters, injunctions, or claims for damages. Consulting with an attorney can help you take the appropriate steps.
What happens if my trademark application is rejected?
If the Trademark Office rejects your application, you have the option to file an opposition or, if necessary, amend the trademark. It is advisable to review the grounds for rejection and, if necessary, determine the best course of action with the assistance of an attorney.
Can I register my trademark internationally?
Yes, by filing an international trademark application (through WIPO), you can protect your trademark in multiple countries at the same time. Alternatively, you can also apply for an EU trademark, which is valid in all EU member states. An expert can help you develop the best strategy for your international markets.
How can I ensure that my trademark remains protected in the long term?
To maintain your trademark protection, you must ensure that the trademark is used regularly and that renewal fees are paid on time. In addition, monitoring can be useful for identifying potential trademark infringements early on and taking action against them.
