Hughes, Circuit Judge.

CardSoft alleges that Appellants infringe two patents directed to software for small, specialized computers, like payment terminals. In construing the patent

claims, the district court adopted CardSoft's proposed construction for the claim term " virtual machine." Applying the district court's construction, a jury returned a verdict for Card-Soft. Because the district court erred in its construction of " virtual machine," and because CardSoft waived any argument that Appellants infringe under the correct construction, we reverse.

Id. at col. 2 l. 64-col. 3 l. 1.

According to the patents, prior art payment terminals used a variety of " different hardware/software architectures." Id. at col. 2 ll. 34-37. But this variety of different architectures meant that each application program for a payment terminal needed to be written specifically for that terminal. Id. at col. 3 ll. 5-11.
