Maia Loses U.S. Appeal on Bracco Patent for Gallbladder Drug

The U.S. Court of Appeals for the Federal Circuit affirmed a federal judge’s ruling that closely held Maia Pharmaceuticals’ sincalide drug, used to stimulate gallbladder contraction, infringes a Bracco Diagnostics patent for Kinevac.

• Patent covers formulations and methods for making and using formulations of sincalide, Kinevac’s active ingredient
• “Because Maia stipulated to infringement under a claim construction that is essentially correct, we affirm,” the three-judge panel wrote in opinion issued Thursday
• The stipulation was based on the New Jersey district judge’s construction of the terms “buffer,” “surfactant/solubilizer,” and “surfactant,” opinion says
