Before MICHEL, Chief Judge, NEWMAN and LOURIE, Circuit Judges.

Microsoft Corporation appeals the denial of post-trial motions concerning a jury verdict that U.S. Patent No. 4,763,356 (the “Day patent”) was not invalid and that Microsoft indirectly infringed the Day patent. Microsoft also appeals the $357,693,056.18 jury award to Lucent Technologies, Inc. for Microsoft’s infringement of the Day patent. Because the validity and infringement decisions were not contrary to law and supported by substantial evidence, we affirm. Because the damages calculation lacked sufficient evidentiary support, we vacate and remand that portion of the case to the district court for further proceedings.
