Heading: The Parties' Burdens on Appeal

Text: 12 To carry its burden on appeal, GTE must show that the district court's ultimate fact findings in respect of anticipation and infringement were clearly erroneous, or that the district court's legal conclusions in respect of non-obviousness and unenforceability were erroneous, or that the fact findings underlying the ultimate findings or conclusions were clearly erroneous. See Atlas Powder Co. v. E.I. Du Pont de Nemours & Co., 750 F.2d 1569, 1573, 224 USPQ 409, 411 (Fed.Cir.1984). 13 To carry its burden as cross-appellant, Rolls-Royce must show that the district court's fact findings on willful infringement were clearly erroneous, and that it abused its discretion in refusing to award attorney fees. 14 The clearly erroneous standard is satisfied when although there is evidence to support it, the reviewing court is left with the definite and firm conviction that a mistake has been committed.
