Nicomedes Sy Herrera is a strategic litigator with over 22 years of experience litigating a broad range of complex, high—impact business and trade disputes, with a particular focus on qui tam and antitrust actions. Mr. Herrera investigated and commenced a series of billion dollar qui tam lawsuits against some of the largest pharmaceutical manufacturers based on the drug companies’ assertion of fraudulently-procured patents to exclude generic competition. The groundbreaking suits allege that in procuring and asserting fraudulent patents, the drug companies unlawfully inflated the price of drugs sold to, or reimbursed by, federal and state agencies.

For example, Mr. Herrera served as Vice-President and General Counsel of Corridor Capital Group Holdings, LLC, in New York, and several of its spin-off entities. His experience leading companies gives him a practical perspective when pursuing high-stakes litigation on behalf of Herrera Purdy LLP’s corporate clients that focuses on achieving business goals and prosecuting cases efficiently.
