Top Ten Most Cited Patent Cases 2007-2010

In the common law tradition, virtually every written opinion from the Federal Circuit cites to prior precedent. I looked at the past few years of Federal Circuit decision to discover the most cited patent cases.

The following list is ranked based on citations found in Federal Circuit patent decisions that were decided January 1, 2007 – May 26, 2010. The ranking is a combined score of both (1) the number of times a case was cited and (2) the depth-of-analysis associated with the citation. I excluded non-patent cases from the list.

1. Phillips v. AWH Corp., 415 F.3d 1303 (Fed.Cir. 2005).
2. Cybor Corp. v. FAS Technologies, Inc., 138 F.3d 1448 (Fed.Cir. 1998).
