The German Federal Supreme Court decides about limitations of a patent claim which are not originally disclosed

The German Federal Supreme Court has confirmed its case law by deciding that a limitation of a patent claim which is not disclosed in the original application can remain in the patent claim. A precondition, however, is that the respective feature only puts a technical teaching in a more concrete form, whereby this technical teaching has to be disclosed as being part of the invention in the original application. In these cases, it is in general not necessary to include a disclaimer.
