In a recent case involving a liquid dosage form of levothyroxine, Sherry helped her client defeat two separate preliminary injunction motions following hearings before Judge Albright in the U.S. District Court for the Western District of Texas and got the case dismissed from two other jurisdictions, which ultimately resulted in a settlement for the client.
