One of Europe’s premier IP firms, HOYNG ROKH MONEGIER is spread across eight offices in Belgium, France, Germany, Spain and the Netherlands, and is in pole position to handle complex cross-border litigation on behalf of some of the biggest names in almost every industry. Locally, it stands out for its partner-centric approach and integrated team of lawyers and patent attorneys – a rarity on the Dutch legal scene – and with the most individuals listed on the litigation table in the chapter, it is well equipped to tackle sprawling disputes. Recently it has been representing technology giant Philips in a patent infringement matter against Asus, with Bart van den Broek and David Owen teaming up to bring home crisp results. Department head van den Broek is at ease devising national and international patent litigation strategies, and Owen’s qualifications as a US patent attorney and lawyer, as well as a solicitor of England and Wales, bring a global touch to everything he does. In the life sciences, Peter van Schijndel and Simon Dack have been supporting Sanofi in infringement and invalidity proceedings. “Peter and Simon are consummate professionals. Simon is super skilled, and his business-oriented approach is always valued, while Peter is really knowledgeable about the law and thinks strategically.” Frank Eijsvogels often joins up with them and is described by his peers as “an excellent litigator who is always willing to go above and beyond”. Joining forces to assist AstraZeneca in several high-profile patent matters surrounding a number of their blockbuster drugs are Willem HoyngJeroen den Hartog, and Theo Blomme. Former managing partner Hoyng is an encyclopaedia of IP knowledge, having seen and done it all over the course of his nearly 50-year career, while organic chemistry PhD den Hartog brings over two decades of in-house experience to bear. “Blomme swiftly understands the essence of a matter and efficiently extracts the relevant facts before translating them into cogent and persuasive arguments. He also develops clear strategies that have the best possibility of success, which he bases on his own experiences.” Michiel de Baat and Wilbert Derks round off the impressive line-up. De Baat has been handling EPO work for Hologic – a medical technology company focused on women’s health – as well as managing their entire portfolio. “Wilbert studies subjects in depth, thoroughly grasps new concepts, asks critical questions and has made significant contributions to his clients’ patent positions through his ingenuity and business-oriented advice.”
