November 18, 2021), the Court issued its claim construction of the two remaining disputed terms of U.S. Patent No. 9,604,901 (“the ‘901 patent”) relating to “an improved process to convert benzindene triol to treprostinil via salts of treprostinil and to purify treprostinil.” The Court adopted the plain and ordinary meaning of the disputed term “pharmaceutical batch” (claims 1-4, 6 and 8) and adopted Defendant’s proposed construction of the disputed term “contacting the solution comprising treprostinil from step (b) with a base to form a salt of treprostinil” (claims 1 and 8).
