In this case the FCJ considered the question of whether one of the co-owners of an invention is individually entitled to file a patent application for that invention. The Court held that in general an application is not permissible if it is made only in the name and on behalf of that co-owner. In such…

In this case the FCJ considered the question of when the enforcement of a judgment in an infringement action should be suspended in light of a decision of the Federal Patent Court in a parallel nullity action concerning the same patent. The Court held that there is no reason for a suspension if the patent…

In this case the FCJ expanded on earlier case law regarding claim construction, in particular how a term used in the claim language should be interpreted in light of the specification and the entire set of claims. The Court held that the subject matter of the main claim can generally not be limited by a…

In this case the FCJ dealt with the prerequisites for equivalent infringement. In particular it gave further guidance in relation to the so-called “3rd Schneidmesser question” which concerns the parity of a variant with the patented solution.

The Court explicitly stated that there is no legal or factual…

In this case the FCJ expanded on earlier case law regarding claim construction and in particular on the issue of whether a certain embodiment would fall within the scope of protection by way of equivalence if the specification in the patent described various options, but only incorporated one of those options into the claim wording….

The Federal Court of Justice held that claim construction has absolute priority before issues of invalidity, such as the inadmissible extension or issues of patentability of the subject matter, can be discussed. The Court also reiterated that the determination of the subject matter of a patent (the invention) cannot be abandoned with the mere reason…

The Court held that a certain means does not relate to an essential element of the invention just because it is used for a step in the method preceding the patented steps of the method. Even where this is necessary in order to apply the method, no contributory infringement of the patent can be established….

In this case the FCJ discussed the criterion of “equivalence” for a non-literal infringement of a patent. The Court held that one has to assess all technical effects which have to be achieved with the patented features to solve the underlying technical problem. The entire combination of these effects forms the patented solution. For the…

The CJEU decided on a referral by the District Court Düsseldorf  with regard to the interpretation of Art. 102 TFEU in the context of patent infringement actions regarding standard essential patents (SEPs).
