The protection of intellectual property is the core competence of our firm and the prototype of intellectual property is patents. They give their owner a valuable monopoly right to an invention. If an actual or potential patent infringement occurs, everything depends on the right attack or defense strategy. As experienced litigation lawyers, we are at your side with competence and experience if your patent is infringed or you are sued for a patent infringement.
Our consulting services in patent law
The patent gives its owner a monopoly right to his invention. Others are prohibited from using the invention without his consent. If they do, the patent owner has claims for injunctive relief, information and damages. Before these claims can be asserted, however, it must first be determined whether the patent has really been infringed. We can help you with this by analyzing the features of the patent claims to check whether third-party use falls within the scope of protection of your patent.
It is not always possible to determine a patent infringement with absolute certainty. You don’t want to take the risk of receiving an unjustified warning, but doing nothing is not a good alternative either. In these cases, it is common practice in patent law to submit a request for authorization to the possible infringer. In this way, you can point out your existing rights and clarify the facts of the case further. In many cases, a request for authorization is enough to stop the patent infringement.
If a patent infringement has actually occurred, the first step is usually to issue a warning. This sets out that a patent infringement has occurred and why. At the same time, claims for injunctive relief and other claims are asserted, including, above all, claims for information and damages.
If the warning is not successful, the next step on the escalation ladder is usually to apply for an interim injunction. This is issued in an expedited procedure, which initially concerns the claim for injunctive relief. The advantage of an expedited procedure is that a judicial decision can be obtained very quickly and relatively cheaply, which the patent infringer then often accepts as a final decision. In this way, a patent infringement lawsuit can be avoided.
In some cases, it is unavoidable to have the existence of a patent infringement clarified in court. In a patent infringement suit, other claims can also be enforced. In addition to the injunction, these include claims for information and damages. As experienced litigation lawyers, we are at your side as a plaintiff or defendant in patent infringement suits.

Proven expertise through specialization in patent law
Patent law is a complicated, specialized subject. That’s why it’s a good idea to seek advice from a qualified specialist. Doctors don’t need to explain this. If you need a dentist, you don’t go to a general practitioner.
In patent law, this is a little more complicated. Many people do not know what the difference is between a patent lawyer, a patent law specialist and a patent attorney. We will explain it to you!
A patent lawyer has passed two state law exams and is therefore qualified as a fully qualified lawyer to advise you as a lawyer. A patent lawyer has an interest or focus of activity in the area of patent law. Unlike a specialist patent lawyer, however, he or she has no proven special skills in this area.
Specialist lawyers are proven specialists in their field of law. In order to obtain the title of specialist lawyer, you must prove to the relevant bar association that you have special theoretical knowledge and special practical experience in the relevant field that significantly exceeds the level that is normally imparted through professional training and practical experience in the profession (§ 2 FAO). Specialist lawyers must also regularly undergo further training or publish academic papers. This ensures that legal advice always takes into account the most current case law and legislation. As a specialist law firm for intellectual property rights, we provide you with highly qualified advice in all areas of patent law.
Unlike a lawyer or specialist lawyer, a patent attorney is not a fully qualified lawyer. He does not have two state law exams. Instead, a patent attorney has completed a university degree in natural sciences or technology and has one year of experience in the technical field. Since patent law cases are often both legally and technically demanding, patent lawyers regularly work together with specialist lawyers for patent law.
