Momenta Pharm. (Cambridge, MA) and its exclusive licensee Sandoz Inc. (Princeton, NJ) have sued Amphastar Pharm. (Rancho Cucamonga, CA), International Medication Systems, Ltd. (Rancho Cucamonga, CA), and Watson Pharm. (Boston, MA) for infringement of Patent Nos. 7,575,886 and 7,790,466 directed to ways of manufacturing generic enoxaparin.
Like similar complaints filed by Momenta, this complaint is based on an announcement by the defendants that the FDA had approved Amphastar’s ANDA for generic enoxaparin. To cover their bases, the plaintiffs include in the complaint not only counts for infringement but also counts for declarations of infringement.
