Firm Details

We maintain long-term relationships by providing highly responsive, personalized service with quality legal work and sound advice.

Since 1957 we have earned our international reputation as a leading intellectual property law firm. We have a deep bench of attorneys experienced in trademark, copyright and patent law who meet together weekly to discuss current issues, and who frequently meet with non-US colleagues.

An adjunct is our unusual practice in customs, international cargo and regulatory compliance law with an ancillary office near JFK International Airport. In addition, we have an active advertising law practice.  We also have successfully represented clients in the areas of litigation, commercial and corporate law, real estate, trusts and estates and private client services.
