Experts in technology and law

In our role as patent attorneys, each of us has a degree in science – in the fields of physics, chemistry, biochemistry, or biology – and has been working with inventions in a wide variety of different technical fields for years.

To be able to represent you in all matters concerning patent law, trademark law, and the law of design patents and registered designs, we are admitted to practice as registered German Patent Attorneys (Patentanwälte), European Patent Attorneys, and European Trademark and Design Attorneys.

All of this means we can represent your interests before the German Patent and Trade Mark Office (DPMA), the German Federal Patent Court (Bundespatentgericht) and in nullity proceedings before the German Federal Court of Justice (Bundesgerichtshof), the European Patent Office (EPO), and the European Union Intellectual Property Office (EUIPO), which is responsible for EU trademarks and designs.

In litigation before civil courts, such as in patent or trademark infringement matters, we work together with attorneys with experience in these types of litigation.
