Zimmermann & Partner Patentanwälte mbB

Zimmermann & Partner Patentanwälte mbB is an IP firm located in Germany, with offices in Munich, Berlin and Bamberg. Zimmermann & Partner has grown steadily since it was founded in 1999; it currently has 30 qualified German and European patent attorneys and an overall staff of approximately 80 people. Zimmermann & Partner provides the complete range of IP law-related services, with a particular focus on patent litigation and prosecution.


Zimmermann & Partner has successfully handled numerous high-profile patent litigation cases in the fields of telecommunications, semiconductor technology, liquid-crystal display technology and medical and consumer products. We are the patent attorneys of choice responsible for representing Samsung in numerous German proceedings, most visibly in international disputes in the areas of telecommunication and electrical engineering. For medical product manufacturer Medtronic, our firm is continually involved in litigation relating to stents, heart valves and catheter technology. In such litigation cases, we work in close cooperation with several of Germany’s top attorney-at-law firms. Our technical expertise is requested by global players not only for German cases, but also in the context of cross-border litigation and in foreign jurisdictions.

At Zimmermann & Partner, we represent clients in nullity proceedings, challenging patent validity before the first and second-instance nullity courts (the Federal Patent Court in Munich and the Federal Court of Justice in Karlsruhe). Special care is taken to balance properly arguments regarding infringement and validity before the respective courts.


Through our extensive litigation experience, we develop patent portfolios and devise patent prosecution strategies for both international players and well-reputed national companies. We assist clients from the outset in R&D, the development of IP strategies, the drafting of patent applications, the prosecution of applications before the patent offices through to grant and the defence of patents in the event that validity is challenged.


Our firm has particular expertise in the preparation and handling of opposition cases before the European Patent Office (EPO), the German Patent Office and the German Patent Court, often doing so with future litigation in mind. We are involved in a high number of oppositions; we take pride in our high success rate, which stands well above the average results as taken from official statistics. Our firm is often contracted by other European patent law firms to assist in difficult cases and assume the lead in oral proceedings before the EPO Opposition Divisions and Boards of Appeal and the Federal Patent Court.

Engagement as court experts

Our partners are regularly engaged as court experts by various first and second-instance infringement courts in Germany. This is an obvious sign of our expertise and the regard in which Zimmermann & Partner is held among the judges at the German infringement courts.

Analysis, due diligence and valuation

We handle numerous other types of client consultation, including due diligence, infringement and validity analysis, work-around strategies, drafting and analysis of agreements and German Employee Inventor Law consultations. In addition, one of our partners has a PhD in patent valuation, making Zimmermann & Partner a frequent competent partner to investors, banks and liquidators, assisting with the valuation of patent and trademark portfolios over many years.

Administration support

We take pride in making the administrative exchange with clients in a smooth, efficient and cost-effective manner. Thanks to our expertise and renowned customer service, large US corporations employ our services as their European patent department. Thus, we have gathered an abundance of experience with numerous standard external administrative software programs such as Anaqua, Tymetrix and Serengeti, so as to directly interface with clients’ own in-house patent departments. We thereby assist, or in some cases take complete responsibility for, the internal docketing processes for these corporations. In addition, we provide flexible and complex portfolio reporting services, as well as generating and developing interfaces with clients’ software, as desired.
