Intellectual Property

Our lawyers have extensive experience in all aspects of patent, trademark, trade secret, false advertising, copyright, and related antitrust and unfair competition litigation. We have defended patent and copyright cases on behalf of some of the world’s largest software manufacturers, medical device producers, transportation providers, and music companies – and prosecuted infringement actions for mid-market companies seeking to protect their intellectual property rights.

We are acutely aware of the critical need to prepare complex cases to ensure that, should they end up in trial, we can deliver a powerful narrative that a lay jury will understand. The firm’s lawyers have been consistently recognized as leaders in this field.


Columbia Data Products, Inc. v. Symantec Corporation, Case No. 6:06-CV-00066-JA-KRS – Represented one of the world’s largest software manufacturers in defense of this copyright infringement and breach of contract action. Following a 2 week jury trial in the Middle District of Florida, the Court granted Defendant’s motion for judgment as a matter of law on the contract claim and the jury returned a verdict in favor of Defendant on the copyright infringement.

John Hinde, Ltd. Et al. v. Levy Marketing, Inc. (S.D. Fla. 2005): Represented a leading international manufacturer of children’s novelty items in this copyright infringement case. Within days of being retained to pursue parties allegedly selling counterfeits of the clients’ products, obtained an ex parte TRO enjoining any further sales by the defendant and authorizing the seizure (with the help of U.S. Marshals) of the offending goods. Once counterfeits were found, forced a settlement that included destruction of all inventory, a recall of all goods previously sold, a permanent injunction, and a substantial payment to the client.
