Upon finding for the claimant the court shall award the claimant
damages adequate to compensate for the infringement, but in no
event less than a reasonable royalty for the use made of the
invention by the infringer, together with interest and costs as
fixed by the court.
When the damages are not found by a jury, the court shall assess
them. In either event the court may increase the damages up to
three times the amount found or assessed. Increased damages under
this paragraph shall not apply to provisional rights under section
154(d) of this title.
The court may receive expert testimony as an aid to the
determination of damages or of what royalty would be reasonable
under the circumstances.
