Firm overview

Especially when it comes to IP litigation, BDPE ensures that any risk of a conflict of interest is kept as low as possible.

The Firm

The lawyers at BDPE specialise in litigation and prosecution in the field of intellectual property and combine branch-specific and technical expertise with legal competence. The firm’s partners have been well known in their fields for over 20 years and are among the few established experts in their clients’ industries. This means we can support you not only in an advisory capacity, but also as real business partners who understand your business.

The firm’s expertise is focused on patent and utility model law, on trademark, design and copyright law, as well as on competition, domain and employee invention law. BDPE’s client portfolio includes worldwide corporations and leading companies in Germany and abroad. The firm works with an international network of contacts with other law firms and patent attorneys.

Competence

BDPE’s competence lies in legal representation in patent, trademark and design litigation, as well as in copyright and competition proceedings, protecting innovations, new technologies and products, brands and new designs, and handling the corresponding grant, appeal and opposition proceedings. The firm provides strategic advice on patent portfolios and in all areas of IP law.

BDPE advises and represents its clients across a broad range of technical areas: automotive, computer technology, electrical engineering, electronics, food and beverage production, LED technology, mechanical engineering, medical technology, optical technology, photovoltaic technology, physics, semiconductor technology, software, telecommunications and video/audio encoding. BDPE further specialises in the following industries and sectors: consumer goods, energy suppliers and providers, fashion, furniture and household retailers and media and communication agencies. As a matter of principle, we do not exclude any business sector or field of technology.

Team

Our team is currently composed of seven patent attorneys and two attorneys-at-law based in offices in Dusseldorf and Munich, Germany. The firm and its patent attorneys are frequently recommended by renowned publications and ranking organisations, and have garnered a truly remarkable amount of praise since the founding of the firm in 2019.

The firm is already one of the most active in patent litigation before the German courts, especially in connection with mobile communications and electrical engineering patents. Our lawyers have been involved in various high-profile patent litigation proceedings, many of which have concerned standard-essential patents and have had international implications. Partners Friedrich Emmerling and Karl-Ulrich Braun-Dullaeus are highly regarded in Germany, particularly for their work in the telecommunications field and for their activities in German nullity proceedings before the German Federal Patent Court.

Diversity

BDPE promotes diversity! Our attorneys and office staff represent a multitude of nationalities from Europe, Asia and the Americas, and speak as many as 10 different languages. This makes it possible, for example, for our firm to interact directly with a broad client base across the globe and understand cultural differences.

We are committed in our hiring practices to seek out diverse lawyers and office staff and to ensure that they are strategically invested in and advanced. We are further dedicated to non-discriminatory hiring practices and believe that a diverse staff is essential to our practice and success.
