Recommended - Individuals: prosecution and nullity

While known first and foremost as a patent attorneys, Maiwald’s 90-strong team of professionals includes attorneys-at-law too, meaning patrons can get all of the answers they need in one place. As one happy patron puts it: “We use Maiwald to prepare our most important and complicated patent applications. Its team of PhD attorneys does a great job of characterising our inventions and preparing applications for filing. They are excellent across the board, with amazing strength in depth.” The life sciences has been an area of growth lately, as reflected by the firm’s recent work managing Takeda’s patent portfolio – taking the lead there is Eva Ehlich, an expert chemist with special knowledge of the US and Japanese markets. Her fellow life sciences mavens are Dirk Bühler, Andreas Ledl and Derk Vos. Bühler is a hit in EPO oppositions and is looked to for his SPC knowledge – so much so that he has co-edited a European handbook on the topic. The “creative, determined and very responsive” Ledl, meanwhile, is intimately familiar with the pharmaceuticals industry and puts his knowledge to use by confecting sophisticated portfolio strategies, while Vos’s chemistry know-how stretches from drugs to pesticides and polymers – he is particularly well known for his freedom-to-operate opinions. Covering everything from chemistry to semiconductors is Norbert Hansen, who can also be relied upon for advice on employee invention law, while physicist Alexander Ortlieb enters the IAM Patent 1000 in 2022 on account of his knowledge of areas including computer-implemented inventions and medical technology, and his ability to conduct oppositions and prosecute patents with equal flair. For companies in the automation, transport and data security fields, the one to call is Christian Schäflein – thanks to his global outlook, many an international corporation has sought out his support of late. Heading up the nine-strong legal team is Marco Stief, who understands clients’ needs, thanks to time spent working within the pharmaceutical legal department of Fresenius. Comfortable in every sector, he has lately been acting in patent infringement proceedings on behalf of major names in the IT, automotive and pharmaceutical fields.

Close cooperation between patent attorneys and attorneys at law is especially important in patent infringement litigation since this type of proceeding generally calls for a comprehensive overview of national regulations and a thorough grasp of the relevant technology. The interdisciplinary teams provide a comprehensive package of services to guarantee the successful conduct of legal proceedings in an international arena, as well as in cases where speed is of the essence, such as in preliminary injunction proceedings and border seizure procedures.

However, Maiwald’s attorneys at law would be the first to acknowledge that litigation is not always the best solution. Therefore, they are also skilled advocates in arbitration and mediation proceedings, as well as trusted experts when it comes to negotiating licensing contracts.
