Maintaining Claim Scope after Johnson & Johnston
The Supreme Court's decision in <i>Festo</i> has been hailed by many as being one of the most significant cases to impact the patent system. <i>Festo Corp. v. Shoektsu Kinzoku Kogyo Kabushiki Co., Ltd.</i>, 122 S.Ct. 1831 (2002). Some say that more significant than <i>Festo</i> is <i>Johnson</i>, in which the Federal Circuit held that subject matter disclosed but not claimed in a patent cannot be covered by the doctrine of equivalents. See <i>Johnson & Johnston Associates Inc. v. R.E. Service Co.</i>, 285 F.3d 1046 (Fed. Cir. 2002) (<i>en banc</i>).
