COHAUSZ & FLORACK was founded in 1954 and now comprises 28 patent attorneys and attorneys at law, as well as approximately 110 support staff. This multidisciplinary law firm has offices in Dusseldorf 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, among other services, drafting and filing, administration and licensing of extensive property rights portfolios, undertaking searches for third-party IP rights and the associated freedom-to-operate expert opinions, as well as 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’s 24 patent attorneys and four attorneys at law possess particular expertise in their respective fields and work 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

The law firm has special expertise in the preparation and prosecution of high-tech patent applications and in the field of inventions that are relevant to technical standards. It also has decades of experience in the prosecution of patent portfolios comprising large international patent families.

Patent litigation and nullification proceedings

Located in Dusseldorf, 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 its 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. COHAUSZ & FLORACK has handled over 1,500 nullification proceedings before the German Federal Supreme Court, the German Federal Patent Court, the European Patent Office and the German Patent and Trademark Office.

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 Dusseldorf Higher Regional Court as the leading patent court in Germany. This goes back to its founding years, when the firm accompanied the relocation of the court from Berlin to Dusseldorf 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 Dusseldorf court’s expertise in the field of information technology and electronics. The firm’s reputation is underscored by its attorneys being repeatedly appointed by the Dusseldorf Appeals Court as court experts.

Expert opinions

Over the past 25 years, COHAUSZ & FLORACK has prepared over 3,800 independent expert opinions on the use of patent-protected inventions in the implementation of standardised technologies.
