Heading: Unenforceability for Inequitable Conduct

Text: 11 Four Star argues that the '658, '471, and '710 patents are unenforceable for inequitable conduct in connection with the prosecution of the '710 patent before the PTO. Even if this issue had been considered by the district court, which is not clear from the record, it is raised on appeal for the first time in Four Star's reply brief. This is in contravention of Fed.R.App.P. 28(c) which specifies that [t]he appellant may file a brief in reply to the brief of the appellee.  (Emphasis added.) Thus, new issues may not be raised in the reply brief. Moreover, Four Star's reply brief is completely devoid of citations to the record to support its contentions on this issue.
