Non-Infringement

A ruling of non-infringement holds that an accused product or process does not fall within the scope of the asserted claims. It is the mirror image of an infringement finding and is reached by the same comparison: the accused instrumentality is measured against each limitation of the claim as construed, and the absence of any single limitation defeats the charge. Non-infringement is frequently decided on summary judgment, because once a term has been construed the question often becomes one that no reasonable jury could resolve for the patentee. The opinions here include summary judgment grants of non-infringement, declaratory judgment actions seeking such a ruling, and appellate decisions affirming or reversing them.
