Their communications are always clear, easy to understand and on time, and fully address our requests. Their teams demonstrate good understanding of client needs and commercial objectives. There is never any delay when dealing with Zimmermann.” Physics PhD Joel Nägerl is an expert in contentious patent proceedings for names in telecoms, electrical engineering, optics and semiconductors. A tenacious and strategic mind, Nägerl is in great demand for his skills as a litigation support adviser and in nullity proceedings. “Benedikt Neuburger puts the client at the centre of his work. He is supportive and competent at the highest level.” An expert in green technology and engineering, Neuburger is a smooth and confident advocate in examination, opposition, nullity and appeal proceedings before the German and European patent offices and the German Patent Court. “Dominique Gobert works with his clientele over the long term. He is very friendly, and his communications are easy to understand. Most importantly, he can analyse the facts of a matter correctly and in great detail, rendering well-thought-out judgements. His advice and service are prompt and always carefully considered. He is also flexible and understands clients well. Dominique carefully drafts the claims and specifications, taking the requirements in foreign countries into consideration. That is very helpful not only for European applicants planning to file foreign applications, but also for local agents handling applications from European countries. He is certainly one of the very best patent attorneys.” “Frank Steinbach and his team at Zimmermann & Partner are the preferred European patent law firm for patent prosecution in Europe at the European Patent Office and the German Patent Office. Frank is a strategic partner who deeply understands patrons’ businesses and their competitors, and proactively develops sophisticated prosecution strategies that protects their products and creates leverage over competitors.

Ginzel is a technically astute operator in technology fields including telecoms, semiconductors and micro-electromechanical systems, thanks to his PhD in physics. He and Nägerl advise Samsung in a number of matters, including invalidity proceedings launched by Tagivan relating to video coding patents, proceedings launched by Netlist relating to memory module patents and against Imberatek in relation to the packaging of electronic modules. The team also supports Samsung in a range of matters.

Zimmermann & Partner has represented clients in nullity proceedings, challenging patent validity before the first and second-instance nullity courts, including the Federal Patent Court in Munich and the Federal Court of Justice in Karlsruhe. Special care is taken to properly balance arguments regarding infringement and validity before the courts.
As a result of Zimmermann & Partners’ extensive litigation experience, the firm develops patent portfolios and devises patent prosecution strategies for both international players and well-reputed national companies. It assists 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.
Zimmermann & Partner has expertise in the preparation and handling of opposition cases before the EPO, the German Patent Office and the German Patent Court, often doing so with future litigation in mind. The firm’s attorneys are involved in a high number of oppositions and take pride in their high success rate, which stands well above the average results as taken from official statistics. The 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
Zimmermann & Partners’ partners are regularly engaged as court experts by various first and second-instance infringement courts in Germany. This is an obvious sign of their expertise and the high regard with which Zimmermann & Partner is held among the judges at the German infringement courts.
