Thus, it appears the court construed
“mixture” to mean “a mixture.” We agree that “mixture”
does not require any additional construction.
however, that the phrase construed by the trial court is
actually “a mixture comprising” various ingredients.
While the claimed mixture must include the listed ingre-
dients, it is not limited to them, and may optionally
include other components in addition to those explicitly
recited. CIAS, 504 F.3d at 1360-61.
