*1339Opinion for the court filed by Circuit Judge LINN.
Dissenting opinion filed by Circuit Judge REYNA.
LINN, Circuit Judge.
TecSec, Inc. appeals from the district court’s entry of judgment that the defendant-appellees (the “defendants”) do not infringe various claims of three TecSec patents: U.S. Patent Nos. 5,369,702 (the “'702 Patent”); No. 5,680,452 (the “'452 Patent”); and No. 5,898,781 (the “'781 Patent”). Because the district court incorrectly construed the claims, this court affirms-in-part, reverses-in-part, and remands for further proceedings.
