Read MoreWhat is the relationship between single means claims and property-dependent claims?
The MPEP draws a parallel between single means claims and claims that depend on a recited property: When claims depend on a recited property, a fact situation comparable to Hyatt is possible, where the claim covers every conceivable structure (means) for achieving the stated property (result) while the specification discloses at most only those known…
