Highly recommended - Individuals: prosecution and nullity
COHAUSZ & FLORACK’s team of 22 partners comprises both patent attorneys and attorneys-at-law, meaning patrons are well served no matter the issue they are facing. Founded in 1954 – and working out of offices in Düsseldorf and Munich – the firm has built itself a sturdy reputation on the German market, especially for patent enforcement and infringement issues. High on the agenda in the past year has been its work for Bayer in relation to both CRISPR technology and mRNA vaccines – it has been taken care of by Arwed Burrichter and Natalie Kirchhofer. Having worked as a patent attorney since 2000 – and with a doctorate in chemistry – Burrichter has all the skills needed to handle complex patent issues within the pharmaceutical field, while biochemist Kirchhofer is also well placed to answer life sciences questions, and is a particular expert in supplementary protection certificate (SPC) law. Working on the electronics side, meanwhile, are Gottfried Schüll, Christoph Walke and Philipe Walter. Physicist Schüll is an oracle when it comes to communications technology and everything SEP- and FRAND-related, while Walke’s knowledge sits in a similar realm, as reflected by his doctorate from the Institute of High Frequency Technology – he now spends his time participating in invalidity proceedings and prolifically prosecuting patent applications. Electrical engineer Walter has been a COHAUSZ partner since 2007 and is known for his work on issues in relation to international licence pools that concern technical standards, as well as on disputes between automotive suppliers and set-top box manufacturers. For mechanical engineering questions, the one to go to is Andreas Thielmann – his tenure as a partner goes all the way back to 1993 and his knowledge has led him to become an honorary judge in the Senate for Patent Attorney Matters at the Federal Supreme Court in Karlsruhe.
Philipe Walter is a qualified electrical engineer who specialises in communication technology, green technology and e-mobility patent law. He also focuses on disruptive technologies, the Internet of Things (IoT) and blockchain, helping clients to establish and monetise patent portfolios, as well as create defensive strategies in these areas. His background as an engineer for a mobile operator gives him great awareness of the challenges that arise from software inventions and innovations in the IoT field.
Mr Walter is a German patent attorney and representative before the EPO. He represents national and international clients in all matters relating to IP law. His clients range from international utility companies and automotive suppliers to high-tech start-ups. His LLM in European patent litigation enables him to assist clients in international disputes spanning various jurisdictions throughout Europe and beyond. In addition to advising clients on the management of international patent portfolios, Mr Walter has an impressive track record representing clients in oppositions, infringement actions and validity proceedings. In this role, he has acted in various contentious matters between smartphone manufacturers and in legal disputes between automotive suppliers and medtech companies. He also deals with patent law issues concerning technical standards in video encoding in connection with international licensing pools.
COHAUSZ & FLORACK was founded in 1954 and now has 34 patent attorneys and attorneys at law, as well as approximately 110 employees. This multidisciplinary law firm has offices in Düsseldorf and Munich. The firm supports clients – both international companies and medium-sized companies in Germany – in all matters relating to IP rights and unfair competition. This includes drafting and filing IP rights applications, administering and licensing extensive property rights portfolios, undertaking searches for third-party IP rights and the associated freedom-to-operate expert opinions, as well as drafting cooperation agreements. COHAUSZ & FLORACK also represents clients in proceedings concerning the infringement and validity of IP rights. The firm sees itself as a strong partner and advises clients proactively, individually and holistically on all IP-relevant issues. To this end, the firm leverages the expertise of its 30 patent attorneys and four attorneys at law in their respective fields, all working together as an interdisciplinary, efficient and trusting team.

In addition, COHAUSZ & FLORACK has extensive experience in IP proceedings in other countries (not only EU member states, but also the United States, China and South Korea) and can rely on its strong network of partner law firms across the world. Internally, COHAUSZ & FLORACK focuses on the long-term development and high-quality training and further education of its employees, all of whom approach the protection of innovations with unparalleled interest and openness. As a result, COHAUSZ & FLORACK can make a decisive contribution to ensuring that companies invest in developments and remain competitive while enriching society with their ideas.
Prosecution of high-tech patent applications

It also has decades of experience in the prosecution of patent portfolios comprising large international patent families.

Patent litigation and nullification proceedings
Located in Düsseldorf, the top venue for patent litigation actions in the European Union, the firm’s multidisciplinary team represents blue-chips, as well as small and medium-sized companies – many of the latter being world market leaders in technology. Whenever intellectual property is at stake, COHAUSZ & FLORACK is available to support clients with the relevant expertise.
Patent litigation actions usually go hand in hand with nullification proceedings. Taking place before a separate court and dealt with in separate proceedings in Germany, nullification proceedings represent one of the firm’s main areas of expertise. For the past 25 years, COHAUSZ & FLORACK has worked on over 100 new patent nullity suits and infringement proceedings per year. In addition, the firm takes on more than 75 new opposition and appeal proceedings each year.
The scope of cases handled ranges from patent infringement actions for pharmaceutical clients involving blockbuster drugs through multinational, multi-patent, standards-related cases in the fields of video compression and other forms of communication to niche market cases for ‘hidden champions’. COHAUSZ & FLORACK believes that collaboration with other law firms helps to generate excellent service for the client’s benefit, rather than a loss of revenue.
Throughout COHAUSZ & FLORACK’s history, the firm has played a significant role in the success of the Düsseldorf court. This goes back to its founding years, when the firm accompanied the relocation of the court from Berlin to Düsseldorf in the 1950s. Recently, the firm acted as German lead counsel in the AVC/H.264 patent litigation cases, thereby further contributing to the globally renowned Düsseldorf court’s expertise in the field of information technology and electronics. The firm’s reputation is underscored by its attorneys frequent appointments by the Düsseldorf Appeals Court as court experts.
Over the past 25 years, COHAUSZ & FLORACK has prepared over 4,000 independent expert opinions on the use of patent-protected inventions in the implementation of standardised technologies.
