The powerfulness of our patent law team is based on a deep understanding of technical and economic contexts. We can rely on many years of experience in out-of-court counseling and judicial enforcement of your claims before the specialized German courts. But we also support and represent you in and out-of-court in the case of claims against your company due to alleged infringement of intellectual property rights and develop strategies for effective defense together with you. We assist you in opposition, nullity or cancellation proceedings before the German and European Patent Offices and the Federal Patent Court as well as before the Federal Supreme Court.
Trademarks communicate the image of your products and are the voice of product marketing. Their value can quickly exceed the material value of a company. We support you in establishing and expanding your trademark portfolio, in monitoring it and in defending it vigorously. KLAKA helps with everything that makes up the "life" of a brand.
The protection of products and product parts by registered and unregistered designs has been of increasing importance for many years. It is an effective instrument against counterfeits. This applies to national designs as well as to designs protected within the EU, to the acquisition of design protection as well as to the enforcement of design rights, out of court and before the courts.
The global market is characterised by free trade. The rules of this international economic exchange are expressed in unfair competition law. Comparative or misleading advertising, product imitation, the headhunting of personnel or price dumping may result in unfair competition proceedings. This affects all sectors, from the automotive industry to financial services, from retailers to the internet trade, or from the pharmaceuticals industry to the increasingly deregulated energy supply market.
