The Patent 1000 focuses exclusively on patent practice and has firmly established itself as the definitive 'go-to' resource for those seeking world-class legal patent expertise.

Bronze - Individuals: infringement

For more than four decades, Bardehle Pagenberg has dominated the German patent scene, combining the skills of patent attorneys and attorneys-at-law to provide a 360-degree offering to its global clientele. “Not only is Bardehle highly capable in the technical patent and litigation aspects of a case, but the team also very quickly gains a good understanding of the commercial aspects of a business, enabling it to help with strategic decision-making.” Notable patrons of late include adidas and Apple, both of which have placed their portfolios in the firm’s care. Handling the adidas work are mechanical engineers Joachim Mader and Christian Haupt, while the Apple brief has been tackled by Johannes Lang and Christof Karl. As well as having a strong strategic eye, Mader is well-known for his proficiency in EPO proceedings, while Haupt brings additional knowledge of IT and computer-implemented inventions and is as strong an EPO advocate as he is an advisor on infringement issues. Lang is similarly well-versed in software and computer-implemented inventions and is well known for his advice on cross-border infringement battles, while Karl is a go-to person for issues around telecommunications patents and patent-related antitrust law. As one of his clients puts it: “His advice is sound and solid and creative at times which has helped us push forward some initiatives that have made it to the market unchallenged. At times, he can work on very close deadline without the quality of the work product to be affected.” Also with telecommunications know-how is Tilman Müller-Stoy, who can be relied on for advice in relation to everything FRAND and SEP. “He is a very well-recognised patent litigator and has a lot of experience with patent litigation in Germany but also has very deep knowledge about cross-border aspects of patent litigation. Tilman has a great grip for what matters in a litigation and he will stay very focused on that. He knows how to present a clear, concise and to the point case in front of court, with the right charisma.” Johannes Heselberger is a fellow litigator, whose background in physics comes in handy in all manner of technical areas, including both pharmaceutical and telecommunications cases. “Johannes approaches each case with exceptional judgement, guiding us to the best decisions possible in a difficult legal environment. Over decades of practising law, he has built a deep well of credibility and respect from the German judges handling patent cases.” Also confident in cross-border cases is Alexander Haertel, whose record in the courts is not to be sniffed at. He combines his patent expertise with knowledge in related areas like trade secrets and unfair competition law. Cooperating closely with these attorneys-at-law is patent attorney Tobias Kaufmann, who has seen it all thanks to time spent as an in-house IPR manager for a leading electronics company. He shares this electronics specialism with Düsseldorf office head Martin Hohgardt, who also works closely with attorneys-at-law, providing infringement and validity advice.
