Before PROST, Chief Judge, BRYSON and WALLACH, Circuit Judges. BRYSON, Circuit Judge. Following trial, a jury in the United States District Court for the District of Delaware found that defendants GlaxoSmithKline LLC and Glaxo Group Limited (collec- tively, “GSK”) infringed U.S. Patent No. 8,303,991 (“the ’991 patent”), owned by plaintiff Vectura Limited, and that the patent was not invalid. The district court denied GSK’s post-trial motions for judgment as a matter of law and a new trial. GSK now appeals from the judgment against it. We affirm. I A Vectura filed this action in 2016, alleging that GSK had directly and vicariously infringed various claims of the ’991 patent. Vectura later narrowed its infringement case to al- lege only direct infringement of claim 3 of the patent. The ’991 patent 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 active ingredient. ’991 patent, col. 11, ll. 48–55. The active ingredient produces the desired chemical or biological effect, while the additive particles promote the dispersion and delivery of the active ingredi- ent into the lungs when the inhaler is activated. Id. at col. 10, ll. 6–16. The specification of the ’991 patent first discloses a method for adhering additive material to the active ingre- dient. The method entails milling solid active particles in the presence of solid additive particles with sufficient en- ergy to break down coarse particles into fine particles, re- sulting in the additive particles smearing over, and fusing Case: 20-1054 Document: 54 Page: 3 Filed: 11/19/2020

onto, the active particles. Id. at col. 2, line 4, through col. 3, line 8. The specification also discloses various composite particles that are created by the disclosed milling method. Id. at col. 11, ll. 44–59; cols. 13–15. The specification con- tains a list of additive materials that promote pulmonary dispersion and are compatible with its milling method. Id. at col. 8, line 62, through col. 10, line 52. Magnesium stea- rate is one of the additive materials discussed in the speci- fication. Id. at col. 10, ll. 4–5. The claims of the ’991 patent cover the composite active particles, not the milling method. Apparatus claim 1 reads as follows: 1. Composite active particles for use in a pharma- ceutical composition for pulmonary administra- tion, each composite active particle comprising a particle of active material and particulate additive material on the surface of that particle of active material, wherein the composite active particles have a mass median aerodynamic diameter of not more than 10 μm, and wherein the additive mate- rial promotes the dispersion of the composite active particles upon actuation of a delivery device. Claim 2 depends from claim 1 and requires the additive material to include one or more of certain compounds, one of which is “a metal stearate or derivative thereof.” Claim 3 depends from claim 2 and requires the additive material to be magnesium stearate. B In the district court, Vectura alleged infringement by GSK’s Ellipta-brand inhalers: the Breo, Anoro, and Incruse devices. Each of the accused inhalers features one or more “blisters,” which are sealed receptacles containing a single active ingredient, an excipient, and, optionally, additive material. The blisters use magnesium stearate as the ad- ditive material and lactose as the excipient. As for the Case: 20-1054 Document: 54 Page: 4 Filed: 11/19/2020

active ingredients, the blisters contain one of three drugs— vilanterol, umeclidinium, or fluticasone. The Breo inhaler features two blisters. The first con- tains a mixture of vilanterol, lactose, and magnesium stea- rate. The second contains a mixture of fluticasone and lactose, but not magnesium stearate. The Anoro inhaler also features two blisters. The first contains a mixture of vilanterol, lactose, and magnesium stearate. The second contains a mixture of umeclidinium, lactose, and magnesium stearate. The Incruse inhaler features only one blister. That blister contains a mixture of umeclidinium, lactose, and magnesium stearate. In preparing the mixtures containing magnesium stea- rate, GSK uses a multi-step mixing process. GSK first mixes the lactose excipient with magnesium stearate in the absence of the active ingredient. That step yields lactose particles that are discontinuously coated with magnesium stearate. After a de-lumping step, GSK then mixes the lac- tose particles with the active ingredient. In that step, small particles of the active ingredient are deposited onto the larger lactose particles, which are already coated with small particles of magnesium stearate. C The district court construed various claim terms in the ’991 patent, two of which are relevant to this appeal. First, the court construed the phrase “promotes the dispersion of the composite active particles” (the dispersion limitation) to mean “wherein a composition that contains one or more composite active particles has increased dispersion of the active material upon activating a delivery device for inha- lation into the lungs by a patient, as compared to the same composition wherein unmodified active particles are sub- stituted for the composite active particles.” Vectura Ltd. v.

GlaxoSmithKline LLC, No. 1:16-CV-00638, 2018 WL 4700222, at *9 (D. Del. Oct. 1, 2018). Second, the court construed the term “composite active particles.” GSK’s proposed construction of that term in- cluded a process limitation requiring that the composite ac- tive particles be “formed by milling . . . using sufficient energy and duration to ensure sufficient break-up of ag- glomerates of both constituents, dispersal, and even distri- bution of additive over the active particles.” Id. at *2. The district court rejected GSK’s proposed construction, hold- ing that the term “composite active particles” does not in- clude a process limitation. Id. at *3–8. The court construed the term to mean “[a] single particulate entit[y/ies] made up of a particle of active material to which one or more par- ticles of additive material are fixed such that the active and additive particles do not separate in the airstream.” Id. at *8. At trial, Vectura’s infringement theory focused on the vilanterol and umeclidinium mixtures in the accused inhal- ers. Vectura presented evidence that those mixtures con- tain active particles coated with magnesium stearate, i.e., composite active particles, even though GSK’s multi-step process does not mix the active ingredient and the magne- sium stearate in isolation, but instead mixes them in the presence of lactose.
