CardSoft loses big time at the CAFC
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
a jury returned a verdict for CardSoft.
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.
