The German Federal Supreme Court decides on the enabling disclosure requirement regarding an invention containing a feature defined by a range without an upper or lower limit

The German Federal Supreme Court came to the conclusion that an invention is not enablingly disclosed when the patent claims contain generalized formulas which universalize the patent-protected area beyond the area available to the person skilled in the art through the teaching of the patent. This applies at least in a case where a feature defined by a range without upper or lower limit is made more definite through two parameters working to counteract one another without the restraints created by the joint effect of the parameters becoming clear.
