Galderma Laboratories, L.P. v. Lupin, Inc., No. 24-1664 (Fed. Cir. 2024)
Annotate this Case
Galderma Laboratories, L.P. and TCD Royalty Sub LP (collectively, Galderma) own and market Oracea®, a doxycycline-based treatment for rosacea. They hold U.S. Patent Nos. 7,749,532 and 8,206,740 (the Asserted Patents), which cover a specific formulation of doxycycline. Lupin Inc. and Lupin Ltd. (collectively, Lupin) filed an abbreviated new drug application (ANDA) to market a generic version of Oracea®, claiming bioequivalence. Galderma sued Lupin for patent infringement under the Hatch-Waxman Act, asserting that Lupin’s product infringed the Asserted Patents.
The United States District Court for the District of Delaware held a three-day bench trial and found that Lupin’s ANDA product did not infringe the Asserted Patents. The court concluded that Galderma failed to prove that Lupin’s product met the specific formulation requirements of the Asserted Patents, particularly the immediate release (IR) and delayed release (DR) portions of doxycycline. The court also found that Galderma did not demonstrate infringement under the doctrine of equivalents.
The United States Court of Appeals for the Federal Circuit reviewed the case. Galderma argued that the district court erred in disregarding dissolution test data from Lupin’s ANDA, admitting evidence from a rebuttal batch, imposing additional claim limitations, and not finding infringement under the doctrine of equivalents. The Federal Circuit found no clear error in the district court’s findings. It held that the district court correctly determined that the two-stage dissolution test did not represent in vivo behavior and that Galderma did not prove its theory of infringement. The court also found no abuse of discretion in admitting the rebuttal batch evidence and no imposition of additional claim limitations. Finally, the court upheld the district court’s finding that Galderma did not prove infringement under the doctrine of equivalents.
The Federal Circuit affirmed the district court’s decision, concluding that Lupin’s ANDA product did not infringe the Asserted Patents.
