Rentsch Partner Ltd is a leading Swiss patent attorney and law firm, founded in 2001 and based in the centre of Zurich, with specialists in all areas of intellectual property. Rentsch Partner advises national and international clients on all areas of IP law and related legal areas, including the registration and enforcement of legal rights in Switzerland and abroad. A particularly established team of specialists has gained unique knowledge in the fields of cryptography, blockchain and fintech. The interdisciplinary team works particularly well at the intersection of technology and law.

Our approach

From the beginning, the firm’s aim was to overcome the traditional separation in Switzerland between applications and prosecution of industrial property rights on the one hand, and judicial and legal enforcement of industrial property rights on the other.

As the first law firm of its kind in Switzerland, Rentsch Partner has, since its inception, combined the entire spectrum of industrial property services provided by attorneys at law and patent attorneys in one legal firm using one common infrastructure.

Today, Rentsch Partner employs 45 practitioners, including 23 attorneys at law and patent attorneys, all specialists in today’s most important fields of technology. Five partners of Rentsch Partner have been elected as non-permanent judges at the Swiss Federal Patent Court, the Commercial Court of Zurich and the Federal Arbitration Board for Exploitation of Authors’ and Neighbouring Rights. The founding partner is the president of the Association of Swiss Patent and Trademark Attorneys. Rentsch Partner is among the few specialised law firms in Switzerland focused on IP rights that handle not only legal disputes in the field of intellectual property, but also the entire range of issues involving industrial property rights – including prosecution of national, European and international patents, designs and trademarks.

Network and services

Zurich, with its economic and innovative strength, has offered the ideal environment to grow. With a strong base of domestic clients, Rentsch Partner has been one of Switzerland’s top three Patent Cooperation Treaty filers in the past years. Further, it figures among the largest Swiss filers of international trademark applications through the Madrid system. The firm can assist a wide range of companies and individuals in developing their innovative capacity and protecting their intellectual property. The patent attorneys and attorneys at law at Rentsch Partner are particularly experienced in advising on the strategic development of IP portfolios worldwide. Rentsch Partner has professional contacts in more than 120 jurisdictions, particularly in the fields of trademark and patent law.

Trademarks, company names, designs, unfair competition and copyright law

In particular, Rentsch Partner offers specialised services concerning applications and registrations for trademarks and designs. From their global experience, the attorneys have acquired special knowledge of transnational registrations and IP portfolios. Due to the firm’s integrated model – which unifies consulting, prosecution and litigation – experience gained from disputes and litigation conducted under civil law can also inform non-litigious advice on applications and strategic advice on portfolio building. Similarly, the expertise acquired during active applications and the constant maintenance of its network ensure fast action in infringement cases, not only in trademark and design law, but also in related areas such as company name disputes, unfair competition claims and copyright matters.

US litigation and arbitration

The recently established Rentsch US litigation desk provides services to minimise the loss of business resources consumed in the resolution of US lawsuits. It aims to help business executives manage their US lawsuits, US lawyers and US legal processes to meet the client’s defined business goals. Often these goals are to complete lawsuits at minimum total cost, in minimum time and with minimum management distraction. A step-by-step process enables an objective, quantitative and statistical evaluation of the legal situation – a tool kit to help establish a rational litigation strategy, to control lawsuit costs and to provide a financial basis to guide critical legal decisions.

Finally, Rentsch Partner has extensive experience in arbitration proceedings, especially relating to IP rights.
