    Choate recently obtained a preliminary injunction for Momenta Pharmaceuticals in a patent infringement action to preserve exclusivity in sales of the only generic form of enoxaparin, which had more than $1 billion in sales in its first 12 months.  Choate immediately sued and moved for a TRO and Preliminary injunction based on infringement of two patents covering methods used in the process of making the product, after another party announced in September, 2011 that it had obtained FDA approval to market a second generic enoxaparin.   Choate successfully obtained the TRO and then a preliminary injunction after several rounds of briefing and hearings, also surviving a motion to dismiss, thereby successfully keeping the rival product entirely off the market until trial.

    Choate represented Tillotson Corporation in multiple district court infringement and licensing actions to enforce a patent to conformable medical gloves, although the ITC had previously declined to enforce the patent prior to Choate’s representation.  Choate nevertheless subsequently enforced the patent and related license agreements in numerous actions in federal courts in Georgia and Illinois, resulting in a number of settlements and significant court rulings preserving Tillotson's ability to enforce the license agreements.  Choate’s enforcement actions resulted in Court rulings supporting both actual and liquidated damages as well as recovery of attorneys' fees, ultimately recovering millions of dollars in additional license fees for the client.
