Over the last 10 years, the firm’s attorneys have played leading roles in obtaining licenses, settlements and/or monetary judgments in excess of $75 million for our clients, and in defending our clients’ products, product designs, trademarks and business practices. In a recent Federal court case, which garnered substantial interest by the financial news media, we successfully represented the defendant before the Second Circuit Court of Appeals in Barclays Capital Inc. v., Inc., permitting our client to continue its financial news reporting practices without modification. This case addressed the scope and viability of the law of “hot news” misappropriation and preemption under the Copyright Act. Read more about our Representative Litigation.
