To enhance fairness in compensating owners of patents used by the United States.

Amends the Federal judicial code to provide that, for purposes of compensating an owner of a patent that is used or manufactured unlawfully by or for the United States, reasonable and entire compensation shall include the owner's reasonable costs, including reasonable fees for expert witnesses and attorneys, in pursuing action against the United States in the U.S. Court of Federal Claims if the owner is an independent inventor, a nonprofit organization, or an entity that had no more than 500 employees at any time during the five-year period preceding such use or manufacture.
