Silver - Firms: prosecution and nullity

The Hamburg-based Uexküll & Stolberg is one of northern Germany’s largest dedicated IP outfits. The outfit prides itself on its prioritisation of client service and its hand-crafted, tailored approach to each individual patron’s needs. Ranging across technical areas, the firm’s patent attorneys are grouped into three groups: biotech, technology and chemistry. With 20-plus years’ experience, Albrecht von Menges takes charge on the biotech side. An expert in genetics, von Menges advises German and international names on patents relating to life sciences, biotechnology and pharmaceuticals. One of his patrons is Danish biotech company Chr Hansen A/S. Von Menges takes care of filing, strategy and oppositions for this industry leader. He has also represented the now-Bayer subsidiary formerly known as Monsanto in EPO oppositions. Bernd Christian Janssen heads the tech practice, though his own work ranges widely across sectors. A tenacious and creative advocate, he is often called upon for tricky and complex opposition work – though he is no slouch when it comes to patent drafting either. Two clients which turn to him for the latter are leading injection-moulded pharmaceutical parts manufacturer H&T Presspart, and AMCOL, one of the world’s leaders in bentonite and bentonite-related products. American multinational chemical company WR Grace turns to Janssen for its European patent opposition to Basell Polyolefin’s patent application for polymerisation processes for polyolefins. Chemistry head Peter Franck has more than 30 years’ experience in the patent profession. World leaders in the industry turn to him for his rock-solid technical expertise and quality patent applications. One such patron is US-based petroleum giant ExxonMobil, for which Franck offers European and international patent applications, as well as representing the company in EPO oppositions. Other leading practitioners at the outfit are André Guder, Heinz-Peter Muth and Martin Nohlen. “André inspires long-term confidence in his clients. He has a deep knowledge of the field and is a professional operator. His advice is structured, pragmatic and straightforward. André is part of a well-equipped and professional firm that delivers strategic, value-added guidance on patent portfolios.” With over 25 years under his belt as a patent attorney, Muth can add significant value – whether in the form of a patentability analysis, a meticulously drafted application or an opinion on a nullity action. Alongside his deep technical expertise in chemistry, Muth has also spent time building up comprehensive knowledge of patent law, adding an LLM to his science PhD. “Martin’s approach to patent work, whether during typical prosecution, oral hearings, or opposition, is creative and comprehensive. Martin inspires confidence with his depth of knowledge, experience and command of the facts relevant to each individual case – it is quite unusual to find this combination of traits in a practitioner.”
