Legal services

Our law firm provides strategic advice on all aspects of patent law, trademark law and design law worldwide.

We systematically support you throughout your entire product development process with regular monitoring and analysis of third-party patents as well as with searches, expert opinions, the filing of patent applications and their enforcement and defense against competitors.

Our patent attorneys represent you before the respective patent offices, the Federal Patent Court as well as the Federal Supreme Court and also accompany your proceedings before the regional and higher regional courts.

As a law firm in the premium segment, we follow the highest quality standards. This is the guarantee for our exceptional track record.

Fields of technology

We have broad expertise in many technical and scientific fields. The main areas of expertise include electrical engineering with specialization in

  • control engineering and
  • communication technology,

mechanical engineering with specialization in

  • mechatronics and
  • drive systems and components

as well as process engineering with specialization in

  • bioprocess technology and
  • medical engineering.

System combining law firm and TechCenter

The law firm and the TechCenter form the two pillars of our system.

The TechCenter is composed of specially qualified, industry oriented patent engineers who provide the experienced patent attorneys of the law firm with a comprehensive technical and practical knowledge base.

Based on this, our patent attorneys can fully utilize their legal expertise. The interaction of engineers and patent attorneys can make all the difference, especially in patent litigation.

State-of-the-art software tools are used in almost every step of our work, so that the acquisition and processing of all relevant data is always carried out at the highest technical level.

Dispute management

Every dispute begins with the consideration of whether to pursue a judicial or extrajudicial and whether to pursue an aggressive or defensive strategy. In this process, we advise you on company-strategic, procedural and financial aspects. Often, the synchronization with parallel validity proceedings such as opposition or nullity proceedings must also be taken into account.

The successful implementation of a legal dispute ultimately stands or falls with the formation of a powerful team consisting of our patent attorneys and external attorneys-at-law.

Patent infringement proceedings

Success in legal infringement proceedings means efficient teamwork with a complete knowledge base.

Therefore, we provide our TechCenter of specially qualified patent engineers to the participating team of attorneys. They systematically determine the technical relationships, taking into account the general technical knowledge, research the prior art and prepare all information in an easily understandable and court-presentable form.

The effective interaction of patent attorneys and attorneys-at-law with the patent engineers from the TechCenter is unique and has proven to be particularly effective in practice.


On the liability side of a dispute, the question of the necessity of design-arounds always arises.

The very conception of a theoretically possible design-around can be a strategically effective measure to steal the attacker's thunder and to strengthen one's own negotiating position.

Our team of patent attorneys and patent engineers at the TechCenter has many years of experience, especially in the conception and legal evaluation of design-arounds.

Development support

We support you right from the start in your development decisions with regard to the patent situation. In doing so, we identify risks of infringement at an early stage and identify well-known and freely usable solutions in order to avoid unnecessary iterations.

We use the knowledge gained in this process to strategically build and manage your patent portfolio. The industry oriented working concept of the TechCenter results in an optimal interface to your business processes.

Patent application procedure

In the application procedures for technical inventions, complex technical issues are brought to the point through our systematic working methods:

Every invention is prepared by the TechCenter in its complete technical depth. This applies to the technical environment of the invention as well as to all invention-relevant technical details.

The law firm will transform this detailed technical information into a robust patent structure.

The implementation is tailored to your competitive environment and takes into account the case-relevant, supreme court jurisdiction.

Validity proceedings

The parallel interaction of legal and technical competences is fully exploited in the adversarial validity proceedings as opposition and nullity proceedings:

The law firm can concentrate fully on the legal issues, while at the same time, the TechCenter prepares the technical facts.

This system enables us to pursue both legally and technically demanding proceedings in an efficient and resource-saving manner.
