In Germany infringement of a patent and validity of a patent are dealt with separately and in different
courts. An infringement suit is heard by a specialized board of a district court, while the validity of a
patent is heard by the German Federal Patent Court in a separate nullity proceeding. Usually the defendant
in an infringement suit initiates a nullity suit as a response to the infringement suit.
Our office represents both plaintiffs and defendants in all stages of infringement proceedings before
the district courts, as well as in nullity proceedings before the Federal Patent Court, and also in appeals
before the German Supreme Court (BGH).
Our services usually start with advising our clients on the chances of success
in infringement and/or nullity proceedings. We advise our clients in matters of preliminary
immediate injunctions and, as the case may be, in defending the interests of our clients against the
threat of a preliminary injunction, for instance by filing protective letters in the relevant courts.
