Founded over 60 years ago, Uexküll & Stolberg is one of the largest outfits of its kind in Northern Germany, with 18 patent attorneys and attorneys at law stationed in twin offices in Hamburg and Munich. Its broad trademark offering extends from prosecution and filing strategy to administrative actions and anti-counterfeiting campaigns; and it regularly steps in on matters which have an international angle. Key clients include coffee producer JJ Darboven, whose trademarks it has managed for decades and which it has lately been defending in EUIPO proceedings over the registration of the mark WINDSOR-CASTLE; as well as German auditing company Dekra, whose brand portfolio has been under its care for about 20 years. Taking care of both is Alexander Thünken, a “safe pair of hands and a consummate professional with in-depth knowledge of trademark law and strong business acumen”. “His level of experience in various industries makes him an invaluable counsel.” Trademarks head Frank Dettmann is “a committed and reliable colleague” who “provides realistic assessments of the chances of success and is flexible towards the needs of his clients”; they include household names such as Duracell.

Business enterprises

Running efficient IP operations is a demanding task that any future-orientated company must accomplish to thrive. One decisive factor for market success is the implementation of novel and advanced solutions. In the past, in-house IP functions have proven to be more than valuable for the evolutions of companies in various fields.

Uexküll & Stollberg is proud to be able to offer its clients this expertise. A fruitful and empowering relationship is critical when it comes to drawing out a company’s full potential, which is why the firm’s attorneys integrate with existing in-house teams.

Science and research institutions

Universities, specialised departments and research institutes encounter highly specific IP issues. First, they need to promote their current and future research and thereby acquire funding. To be eligible for funding programmes, intellectual property must be undisputed. Second, work, revenue and income depend on intellectual property, whether through licences or spin-outs.

Before any income can be generated, however, a close evaluation of the commercial potential of a particular product or service must take place, and IP rights must be secured early on in the process.

Law firms

Every law firm has their specific demands, which is why Uexküll & Stollberg offers tailor-made solutions to clients and map out reliable strategies that convince by their practicality, viability and efficiency. Being assigned directly or via an agency, it is always the firm’s target to provide clients with quick responses and business-orientated solutions, including litigation support in contentious proceedings.

The firm’s attorneys possess relevant backgrounds in a variety of technical fields and their experience of proceedings and general court practice allows them to handle even the most complicated legal issues with mastery.
