Vectura Ltd. v. GlaxoSmithKline, LLC, No. 20-1054 (Fed. Cir. 2020)Annotate this Case
Vectura sued GSK in 2016, alleging direct infringement of claim 3 of the 991 patent, which concerns the production of “composite active particles” for use in pulmonary administration, such as in dry-powder inhalers. The composite active particles described in the patent consist of additive material that is adhered to particles of the active ingredient. The active ingredient produces the desired chemical or biological effect, while the additive particles promote the dispersion and delivery of the active ingredient into the lungs when the inhaler is activated.
The Federal Circuit affirmed holdings that the patent was infringed and not invalid. The court rejected arguments that Vectura failed to present substantial evidence that the accused inhalers use additive material that “promotes the dispersion” of the active material, that the district court’s construction of the term “composite active particles” was erroneous, that there were flaws in the calculation of the royalty proposed by Vectura’s damages expert, and that Vectura made prejudicial references to GSK’s sales and advanced an improper “pennies on the dollar” argument in comparing Vectura’s royalty request to GSK’s sales.
