Claim Chart


A claim chart includes a re-writing of an independent claim so that each element of the claim is separated from the other elements for analysis purposes. If an individual claim element is found in an accused device, a "Yes" is placed next to that element. If the individual claim element is not found in the accused device, a "No" is placed next to that element. A single "No" can defeat a charge of infringement. That is why an independent claim must contain only the essential elements of an invention.
