1Opinion of the Court
RADER, Circuit Judge.
On summary judgment, the United States District Court for the District of Delaware determined that CFMT, Inc.’s U.S. Patent No. 4,778,532 (the '532 patent) and U.S. Patent No. 4,917,123 (the '123 patent) are invalid, CFMT, Inc. v. YieldUP Int’l Corp., 92 F.Supp.2d 359 (D.Del.2000), and, after a bench trial, unenforceable, CFMT, Inc. v. Yieldup Int’l Corp., 144 F.Supp.2d 305 (D.Del.2001). Because the district court erred in applying both the enablement and inequitable conduct requirements, this court reverses-in-part, vacates-in-part, and remands.
