Broad-based expertise in all areas

For many companies, technological innovation forms the basis of their commercial success. Patent infringement proceedings can have repercussions that affect the very foundations of the company, regardless of whether it is the plaintiff or the defendant. We have successfully advised clients for decades on all key issues regarding the infringement, legal validity, and exploitation of patents and utility models, as well as on the protection of inventions and know-how. We focus on complex national, pan-European and international patent disputes. The regular engagement of our practitioners in landmark supreme court cases in Germany also contributes to the development of patent case law.

JUVE Handbuch 2019/2020
“... has an excellent reputation.”

We represent plaintiffs and defendants at all stages of legal proceedings and in all German patent litigation courts. These include preparatory proceedings for the preservation of evidence, injunction proceedings, patent infringement proceedings, and invalidity proceedings before the Federal Patent Court and the Federal Supreme Court.


They also include opposition proceedings before patent offices, national and international arbitration as well as customs supervision and border seizure proceedings. Over the past ten years we have litigated more than 100 patent infringement cases.

Transactional & advisory

In addition to our forensic activities, our client offering spans the full range of patent-related legal services (with the exception of patent applications), such as preparing freedom-to-operate analyses, assessing workarounds, developing protection strategies, conducting technology transfers, and setting up and managing patent pools.


Technology transfers are a particularly important part of our practice. We draw up and negotiate complex agreements for licensing, for the transfer of patents and know-how, and for cooperative research and development endeavours. Here our clients benefit from our full-service approach that allows us to call on recognised experts from other practice areas within our firm (such as public assistance or antitrust law) to ensure the provision of comprehensive and integrated advice.

Technology-driven industries

The areas of technology on which our patents team places particular focus include pharmaceuticals and life sciences, consumer electronics, and information and telecommunications technology. We also have substantial expertise in disputes concerning standard-essential patents.


Furthermore, we have litigation experience in numerous other technology-driven industries, including automotive, mechanics, and mechanical engineering, process engineering, chemicals, medical devices, biotechnology and semiconductors. Our constant dealings with complex technical issues as well as our close cooperation with external patent attorneys and other experts in technology ensure that our advice is technologically sound, creative and efficient.

Multinational disputes

We regularly provide advice in multinational disputes, which sees us coordinating legal tactics and patent litigation proceedings across various jurisdictions or working closely with colleagues in other jurisdictions.


This is where clients benefit from our infrastructure and resources as one of Germany’s largest law firms. We have an international network of top patent law specialists, allowing us to put together highly flexible teams of recognised patent litigators in Europe, the US, Japan, and other major jurisdictions that are tailored to our clients’ needs in cross-border patent disputes.
