A much sought-after IP lawyer for his ability to provide IP services across the full spectrum, Chu always has all bases covered, from trademark prosecution, portfolio management to IP transaction and litigationmatters.

Silver - Firms

CMS has trademark stars stationed throughout Europe and Germany is no exception. From cross-border litigation to the coordination of international brand strategies, the firm does it all and more for its blockbuster clientele. Making a name for the group are Gordian Hasselblatt and Carsten Menebröcker. Based in Cologne, Hasseblatt is as confident acting in complex disputes as he is dispensing carefully considered trademark clearance advice; peers call him “a thought leader of German trademark law and a dedicated fighter”. Also adept at cross-border proceedings, Menebröcker brings valuable experience from time spent working for a firm in San Francisco.

Intellectual property is one of your most important assets, and CMS is there to help you secure and protect your precious know-how. A cohesive IP strategy, including both commercialisation and enforcement, ensures you get maximum value from your portfolio.

We support you by advising on trademark registrations, oppositions and portfolio management, globally and locally. If disputes arise, we are there to guide you through the litigation process, whether you are pressing or defending a claim locally or across national borders.

Patent prosecution

Our full-service, in-house patent attorney team has specialists in all areas of technology, and we draft, prosecute, defend and challenge patents in patent office proceedings. We represent clients before the EPO, as well as national patent offices.

Patent litigation

International patent litigation presents difficult challenges and a wide range of strategic options across multiple countries. Our specialist advisers are experienced in cross-border patent disputes and are skilled coordinators of multi-country advice, working without fuss and focusing on client service.

At the same time, we offer efficient and cost-effective local litigation services, even in relatively small disputes.

Trade secret specialists

Half a century ago a company’s value was overwhelmingly derived from its physical capital – the assembly lines and buildings it owned, and the products it made. Today’s firms are built on intangible capital, with assets in the form of software algorithms, brand, customer data, business plans, engineering specifications, product formulas and organisational capital. Our specialist lawyers are happy to assist you so that your secrets are kept secret!

Sector-specific legal advice

At CMS, we recognise that you require sector-specific legal advice to achieve the best possible outcomes. To provide you with commercial, practical advice, we need to understand the markets within which you operate. That is why we have established a number of cross-border practice area and sector groups with representatives from different CMS jurisdictions.

Our practice area and sector groups provide you with integrated services combined with leading-edge industry sector capability.
