The Court of Appeals for the Federal Circuit (CAFC) has issued a number of interesting rulings this year that impact our understanding of the U.S. Patent Law. We have grouped nine of the most interesting decisions and written a short exposé regarding them. See our Bulletin: United States Court of Appeal Decisions in Patent Cases in 2003

U.S. Supreme Court vacates the Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co. decision of the Court of Appeals

The U.S. Supreme Court on May 28, 2002 in a unanimous decision vacated the Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co. decision of the Court of Appeals for the Federal Circuit. The Court of Appeals decision had been very controversial since it established a complete bar to the doctrine of equivalents if a claim had been amended.

The Supreme Court acknowledged that the doctrine of equivalents introduces uncertainty into the issue of claim interpretation. However, the Court disagreed with the complete bar rule set out by Federal Circuit, preferring instead a flexible approach to the doctrine of equivalents. For more discussion of this decision, see our recent Special Information Bulletin.

A copy of the Supreme Court's decision, in pdf format, is also available on-line.
