JUVE Patent

Back to all Firm Profiles


Heuking Kühn Lüer Wojtek (HEUKING) is one of Germany’s leading full-service law firms, offering legal services across eight offices in Germany and an office in Zurich. Heuking Kühn Lüer Wojtek’s patent law team focuses on patent litigation and trade secret protection and is particularly known for its experience in infringement proceedings and in nullity appeal cases at the German Federal Court of Justice (Bundesgerichtshof). The team is highly experienced in guiding companies through all types of patent proceedings before German courts, the European Patent Office, and the German Patent and Trademark Office. In addition, the team is of course well prepared for proceedings before the new Unified Patent Court and is looking forward to the opportunities and challenges that this new system will present. It is known for its excellent technical understanding and its perfect integration into the legal context.

Over the past few years, HEUKING’s patent team, led by Anton Horn, has steadily evolved. All lawyers that are members of the team are also Certified Specialist Lawyers in Intellectual Property Law (Fachanwälte für Gewerblichen Rechtsschutz). At the beginning of 2022, a first European Patent Attorney was added to the team so that it no longer consists only of lawyers since then. This addition strengthens the firm’s patent litigation expertise, but also enables HEUKING to offer patent prosecution services in the future. To achieve this, the team has been further expanded to include an experienced patent attorney, a patent attorney trainee and two paralegals. This development fits well into HEUKING’s full-service offering, as clients now have access to expertise not only in patent litigation, but also in patent prosecution.

The team has also assisted clients in proceedings throughout Europe (Switzerland, where the firm has an office, Austria, Italy, France, Spain, and The Netherlands) and worldwide. It regularly works in the following languages: English, German, French, Italian, and Spanish.  In terms of internationality, HEUKING is well positioned due to its membership in the World Services Group (WSG) network through which the firm enjoys access to and well-established working relationships with excellent patent litigators around the world.

HEUKING’s patent team is part of a full-service law firm with more than 400 lawyers. It has a proven track record of collaborating with its peers in other fields of law, such as unfair competition (e.g., where misleading statements are made about pending litigation), criminal law (e.g., where false statements of fact are made), and public procurement law (e.g., where patents play a role in the selection of a bidder). Due to the firm’s full-service approach, all other legal issues can also be handled quickly and with the highest quality from a single source.

Many clients are mid-sized firms with their business in highly profitable niche technologies, but also major and globally operating market leaders.
