Intellectual property > Trade marks

IP boutique Rospatt Osten Pross, based in Düsseldorf and Mannheim, is renowned for its powerful trade mark, design and copyright litigation practice. Clients benefit from the firm’s expertise in the hard IP and soft IP arena, offering a one-stop IP shop service. The team is particularly active in advising on grey and parallel imports of pharmaceuticals and low-cost electronic goods. In 2020, the team achieved two major successes, in October before the ECJ on the right-preserving use of the Testarossa trade mark and once before the ECJ on the risk of confusion with regard to non-distinctive trade marks, specifically the CORNEREYE trade mark. Key figures are Rüdiger Pansch (patent, trade mark and design law), litigator Max von Rospatt as well as Hetti Hilge and Stephan von Petersdorff-Campen, who cover all IP and competition law matters.


‘Very broad and deep IP expertise – industry know-how in many sectors. Good service mentality, lean teams.’

‘We appreciate the uncomplicated and always reliable consulting practice and the practical problem-solving skills of the lawyers.

Rüdiger Pansch: Outstanding litigator, especially for fundamental and complex issues, particularly experienced with proceedings at the ECJ, always realistic and reliable assessment of risks, opportunities and problems of a legal case.

The firm: For more than 70 years, Rospatt Osten Pross (ROP) has been a specialist in patent litigation. The firm’s offices are located in Düsseldorf and Mannheim, the leading venues for patent litigation in Europe, but it operates in all of Germany and also sides litigation with colleagues in other countries. The firm handles more than 100 patent litigation cases each year in Germany alone.

Due to the high number of cases that ROP handles, the lawyers know the judges that decide patent infringement cases as well as validity cases. ROP also knows the ‘hot topics’ and their possible solutions. The knowledge and experience is spread among all members of the firm because ROP still has a manageable size which allows for a close exchange. ROP’s clients value the efficient and focused work.

International and national companies entrust ROP with their prestige litigation cases just as well as the day-to-day contingency patent work.

Areas of practice: One focus of ROP’s work is litigation. The lawyers secure the entrepreneurial basis of clients’ businesses by defending and enforcing their IP rights or warding off attacks from competitors. ROP appears before all German and European courts, and the German and international offices for trade mark and design protection. The firm is frequently assisted in its work by independent patent attorneys. ROP’s experience with multinational trial series and its good contacts with firms in other countries enable it to provide clients with multinational strategies and concepts at short notice whenever the need arises.
