A newcomer to the IAM Patent 1000 this year, IPrime Legal is a nimble boutique with a lot to offer. Its technically diverse patent attorneys and technology experts work hand in glove with a seasoned troop of business lawyers and litigators to provide a top-notch service that not only protects innovations, but defends and commercialises them too. With Rudolf Rentsch leading the line, the side is ideally placed to handle complex infringement proceedings that transcend borders, especially in the United States, China and Japan. Computers, telecommunications and software are his metiers. Fellow ICT specialist Thomas Kretschmer brings abundant experience to the table, having previously spent almost two decades at leading multinational corporations. He understands the pressures faced by in-house counsel, translates their needs into finely drafted applications and sees them through to grant.

Firm Profile

IPrime is the first Swiss-European boutique group providing highly specialised services in complex matters of technology law, intellectual propety and compliance to high-profile clients. With offices in Zurich, Switzerland and Dusseldorf, Germany, where one of Europe’s leading patent courts is located, IPrime is ideally placed to provide quality IP services in Europe and worldwide.

Relying on a unique combination of experienced business lawyers and litigators, patent attorneys and technology experts with backgrounds in engineering, chemistry, microbiology and information technology, IPrime is able to offer high-end legal and strategic advice and advocacy services in connection with the protection and commercialisation of innovations, investments into technology, as well as complex IP and commercial disputes.

Key strengths of the team are its independence and close collaboration between Swiss and European patent attorneys with a profound understanding of technology and science (including artificial intelligence, robotics, big data, cyberphysical systems and block chain, pharmaceuticals, chemicals and biotechnology, as well as medical technology), and highly experienced dispute resolution specialists, who routinely represent parties in legal proceedings before courts, authorities and arbitral tribunals.

IPrime has for years handled a significant share of all patent litigation matters before the Swiss Federal Patent Court. Additionally, IPrime benefits from broad experience in the IP and technology transfer segments also in the United States and Asia, especially China and Japan, both in the prosecution and litigation of patents and trademarks.

As a part-time judge at the Federal Patent Court and experienced patent litigator, Rudolf A Rentsch is involved in many high-stake patent cases in various technology sectors, while Anne-Catherine Hahn, who joined IPrime as partner in 2019, brings a wealth of experience in commercial litigation, arbitration and compliance. This interdisciplinarity, as well as the many years of experience which its lawyers gained in other firms and in-house roles in the technology sector, enables IPrime to provide cutting-edge legal and strategic support to domestic and international clients at the crossroads of technology and law.

Other key differentiators are the boutique structure and the discretion and substantially reduced risk of conflicts of interest, thanks to which IPrime can provide a broad range of services in contentious matters, from counsel mandates in litigation and arbitration, over arbitrator appointments to acting as mediator or settlement facilitator in situations requiring not only legal knowledge, but also a thorough understanding of the underlying technical and commercial issues.

IPrime’s IP department covers both patent prosecution and patent litigation cases at Swiss, European and international level, providing strategic and legal advice with respect to the protection of intellectual property, whether under patent, trademark, copyright, trade secret, design or unfair competition laws. In particular, IPrime frequently advises IP departments of large leading global high-tech companies, as well as small and medium-sized enterprises, universities and start-ups in all areas of intellectual property, including licensing and distribution agreements. IPrime also offers comprehensive services for the registration and administration of patent and trademark portfolios throughout Europe and overseas. In addition, IPrime’s patent attorneys and lawyers are frequently involved in complex IP disputes, particularly in the patent area, and have accompanied a number of companies in patent cases in the United States, China and Japan, as well as many countries within Europe, in particular Germany and England. IPrime also routinely advises on the commercialisation of intellectual property and related financing and structuring considerations, and has recently set up a partnership with a large Swiss tax and accountancy firm to assist companies in the tax-optimal structuring of patent portfolios, in accordance with the recent introduction of so-called ‘patent boxes’ into Swiss law.
