The IRS appealed, arguing that the legal fees ought to be understood as a cost of acquiring approval from the U.S. Food and Drug Administration (“FDA”) to market the taxpayer’s generic drugs and should therefore be treated as capital expenditures.

The Third Circuit held the Tax Court correctly determined that patent litigation is distinct from the FDA’s scientific review process and not actually facilitative of generic drug approval.
