As far as European IP boutiques go, it is hard to beat HOYNG ROKH MONEGIER, a firm that handles some of the most complex and high-profile patent disputes continent-wide. Its German contingent is a key component of this offering, serving a diverse and illustrious clientele from its base in Düsseldorf and branch office in Mannheim. Key among said clients is Fujifilm, which it has recently been fighting hard for in infringement proceedings against a US competitor. Leading on the case is Tobias Hahn, with Christine Kanz at his side. Hahn has been working in patents for the best part of two decades, is well placed to advise on parallel US and European litigation, and ably handles FRAND- and antitrust-related cases, while Kanz’s focus is on pharmaceutical disputes. The latest highlight in a 20-year-career is her work acting for Gilead in an SPC-related battle, alongside Mirko Weinert, who works either side of the contentious/non-contentious divide and pairs his patent work with a thriving trade secrets practice. He is also part of the team advising Huawei on a range of issues including SEP licensing – working alongside him are Kay Kasper and Stefan Richter, and leading on the work are Tobias Hessel and Klaus Haft. Kasper is also an expert when it comes to SEP licensing, fighting related cases in court and advising automotive companies on portfolio strategy, while Richter has spent the last decade working with IT and telecommunications patents, as well as committing himself to a healthy amount of data protection work. Hessel, on the other hand, is known for his record acting in opposition and nullity proceedings before the EPO, while Haft takes naturally to even the most complex medical devices and high-technology patents, thanks to his background in physics. Leading the department is Martin Köhler, who since 1998 has acted for some of the biggest names in fields including pharmaceuticals, telecommunications and electronics – including his recent high-profile work for Samsung. Completing the line-up in this year’s IAM Patent 1000 are elder statesmen Christian Osterrieth and Thomas Reimann, who have been in the game since 1984 and 1973, respectively. Both effortlessly craft multinational litigation strategies across all patent-rich industries.

Kay N Kasper's Profile

Kay N Kasper passed the German Bar exam in 2002 and has primarily been acting in patent litigation cases since. In the past few years, he has supplemented this established practice with representation of clients in arbitration and he increasingly acts as a professional consultant in out-of-court negotiations and as a negotiator, in particular in licence negotiations concerning standard-essential patents (SEP). In this capacity he assisted BMW in the negotiations with the licensing platform Avanci. Mr Kasper is a certified global negotiator, certified by the University St Gallen, and a trained commercial mediator.

In court he focuses on the coordination of large SEP-portfolio litigation, especially in the telecoms area. Proceedings abroad, as well as preparatory strategic consulting in the case of such multinational conflicts, form an important part of his practice. Litigation in the field of SEP and consulting on the FRAND criteria are the areas on which he currently focuses.

Mr Kasper has gained considerable experience in technical areas such as telecommunications, information technology, automotive and medical devices, as well as in the fields of mechanics, coating and packaging technologies and, most recently, in litigation of risk-reduced tobacco products.

Mr Kasper has specialised in intellectual property, and patent law in particular, since starting his studies in 1994. During that time he has received practical training from the German Patent and Trademark Office, as well as various German and US patent attorney and law firms in Frankfurt, Munich and New York. During his legal clerkship at the Regional Court of Frankfurt, he worked for a chamber which specialised in copyright and trademark law.
