Practice Areas
Rights that work.
Trademark Law
Trademarks create identity. Whether name, product identifier, advertising slogan, logo, or melody: I accompany my clients from the initial clearance search through national, European, and international registrations to ongoing monitoring and enforcement of exclusivity.
Design Law
Whether simple, highly complex, or innovative design – new and distinctive forms deserve protection. I assess your options and guide you through: from research to filing national, European, and international designs, monitoring, and enforcement.
Competition Law
Is your planned marketing campaign legally compliant? Beyond preventive risk analysis, I advise on competitive compliance of market appearances and represent you in defending and enforcing claims arising from unfair competition.
IP Licensing
Your trademark or design has succeeded. Expansion is the next step. I develop licensing models that unite legal precision with commercial objectives, provide security, and preserve economic flexibility.
IP Strategy
I consider IP rights not in isolation, but holistically and with foresight. When building international portfolios, initial decisions have long-term consequences. I disclose the implications and follow-on costs of your choices so that your assets remain commercially calculable.
IP Litigation
Is your IP right being infringed? My services include conducting cease-and-desist proceedings, representation in preliminary injunction proceedings, and litigation in infringement actions for trademarks, designs, copyrights, or unfair competition.
Germany · Europe · International
Trademark Registration: from filing to certificate.
Individual Advice
Comprehensive advice prior to a trademark application. Transparent analysis and clear communication of registration prospects, legal risks, and costs.
Clearance Search
Checking for conflicts prior to a market launch or trademark filing is essential to best prevent costly infringement claims.
Scope of Application
I prepare the goods and services specification tailored to your project – individual, strategic, and future-oriented.
DE · EU · International
Is a Community trade mark advisable in the specific case, or is a national filing later strategically extended internationally recommended? I analyse your geographical protection needs and select the appropriate rights system.
Administration
To relieve your burden, I assume ongoing representation of your trademarks before the DPMA, EUIPO, and WIPO, and reliable monitoring of use requirements and protection expiry deadlines.
Monitoring
In cooperation with CompuMark, I carry out professional conflict monitoring and proactive defence of your trademark rights.
Fees
Trademark registrations are billed on a flat fee basis, calculated according to the number of classes. Official fees of the respective trademark offices are charged separately and advanced by the firm.
Benefits of Registration
- Protection from imitation: Your registered trademark may not be used without prior consent.
- Transferable: Trademarks can be sold or transferred.
- Licensable: Usage rights generate licence income.
- Strategically deployable: Targeted enforcement against competitors.
- Unlimited lifespan: The only IP right renewable indefinitely at 10-year intervals.
- Deterrent effect: The ® symbol signals: this mark is protected.
Risks without Advice
- Risk of direct refusal on absolute grounds (non-distinctive sign), resulting in loss of application fees.
- Costly infringement notices or legal action from prior third-party rights, potentially leading to an immediate sales ban and, in conflict cases, forced costly rebranding.
Trademark registered. What now?
Registration marks the beginning of maintenance: trademark management, deadline monitoring, conflict surveillance. I assume the permanent representative role before the office and provide lasting relief.

Personal. You work directly with the principal. No delegation to associates or junior partners.
Unambiguous. Clear communication about opportunities, risks, and costs forms the reliable foundation of my legal advice.
Precise. Templates are foreign to me. Every IP strategy is as individual as your idea and is tailored precisely to you.
Economical. Your commercial objective and IP budget set the course. My goal is the legally secure development of your assets.
Advisory. You may expect a clear recommendation from me. But the final decision is yours — well informed and in full knowledge of all consequences, including on the cost side.
Prior to engagement you will receive a cost estimate: either on an hourly rate basis, or, for clearly defined service scopes such as trademark or design registrations, as a fixed flat fee.
Philosophy
Negotiate rather than litigate,
when it is promising.
Eye to Eye
Intellectual property is not purely a legal matter — it is a central value driver for your company. I see my role not as purely reactive legal advice, but as strategic partnership at your side.
My Guiding Principle
My legal practice follows two maxims: true protection arises not in dispute, but through unambiguous clarity of one's own position. And: a won case is good — a commercially intelligent amicable settlement is, as a rule, better for your company.
Clear Recommendations
After evaluation, I present the legal situation and possible courses of action. You receive an unambiguous recommendation; the final decision, however, is yours.
AI
Innovative technology
meets years of expertise.
Artificial intelligence has become indispensable in legal practice. I regard AI as a powerful tool that complements legal expertise — it certainly does not replace it. Strategic planning, legal assessment, and ultimate responsibility remain unchanged and exclusively mine.
And what remains unchanged
The Human Factor.
Empathy and sensitivity cannot be replaced by any AI. The human dimension remains foremost — in my collaboration, in negotiations.
