Dey's patent is a formulation patent:

Compositions and methods for treatment, prevention, or amelioration of one or more symptoms of bronchoconstrictive disorders are provided. The compositions provided herein are stable solutions of a bronchodilating agent, or a derivative thereof, in a pharmacologically suitable fluid that contains water, that are stable during long term storage. The compositions are suitable for direct administration to a subject in need thereof. Pharmacologically suitable fluids include, but are not limited to, polar fluids, including protic fluids. In certain embodiments herein, the compositions are aqueous solutions.

This sort of patent is typically used defensively (indeed Xopenex is defended by a fairly strong-looking formulation patent). Using them offensively is much harder, because by definition the broader the patent claim (and this one is very broad) the harder the patent is to sustain.
