My office has often benefited from his expertise and years of experience. His sympathetic way of dealing with his fellow human beings and his pronounced negotiating skills make him a particularly good lawyer for me.’

‘For many years we have been working exclusively and very well with Markus Vogelheim together. He represents us nationwide in all contractual matters, in out-of-court mandates and in court proceedings on the part of the defendant and the plaintiff. Mr. Vogelheim classifies the facts for us competently, calmly and objectively and realistically with a lot of experience – and thus directly usable for the management. He reduces the facts to the legal essentials, which represents a further quality for all parties involved. In the solutions he proposes, he combines the legal, economic and corporate strategic perspectives in a result-oriented manner.’

‘Miss Dahmen is an incredibly dedicated lawyer who is really there for us at any time of day or night and never misses appointments or tasks. She accompanies our issues in court and out of court excellently and very personally with the greatest commitment.’

Intellectual property > Patent litigation: solicitors Tier 4

CBH Rechtsanwälte advises on a broad spectrum of hard IP matters and handles patent disputes, including validity proceedings, employee's inventions, licensing issues and the interface between antitrust law and IT. The management trio consists of Stephan Gruber and Hannes Jacobsen in Munich and Jens Kunzmann in Cologne. The Munich office gained another partner with the promotion of Paul Szynka (patent law, utility model law, competition law) in January 2021.

Other key lawyers:


‘I was particularly impressed by the comprehensive knowledge of the case law of the Federal Court of Justice and the higher courts.’

‘Stephan Gruber: Extensive knowledge of all questions of substantive and procedural law. I am still impressed that he knows the appropriate BGH decision for every question and you can be sure that there is nothing Mr. Gruber does not know. Hannes Jacobsen is certainly one of the most talented litigators of his generation. Technically brilliant.’

‘CBH offers expertise in the IP sector that is rarely found in technology companies, combined with strong industry experience. CBH is a leader in the area of licensing law and employee invention law in particular. The response time is remarkably short compared to the competition. The hourly rates and the type of billing are pleasantly fair, which creates trust.’

‘Jens Kunzmann works very professionally and gives clear and pragmatic advice. He has a strong understanding of his clients’ interests and business. In addition to his above-average expertise in licensing law, he is also characterized by his creativity in approach and argumentation. In addition, Mr. Kunzmann is very pleasant to deal with, so that working together is fun.’

‘When advising on patent infringement litigation, the CBH team always focuses on the interests of the client. CBH’s lawyers work together with the client and the patent team to find solutions that are aligned with the client’s commercial goals.’

‘Hannes Jacobsen and Paul Szynka: well-founded advice in the interests of the client, fast response times.’

‘The CBH team is optimally put together. Stephan Gruber is something of a legend in the patent law field and noticeably passes his experience on to his young colleagues – when we work together, I feel that the team works extremely well.’

‘The support provided by CBH is based on convincing teamwork – but I would like to emphasize the support provided by Hannes Jacobsen. Like others, his accessibility and technical expertise are at an excellent level – but I would like to emphasize his commitment: Mr. Jacobsen formulates his assessments in concrete terms and formulates remaining risks. This quality is extremely helpful for in-house counsel, since risk assessments of alternative or selected procedures are also communicated within the company.’
