Marsha G. Gentner

Senior Counsel

Marsha G. Gentner helps clients strategically manage their global trademark and copyright portfolios. With extensive experience prosecuting and litigating before the U.S. and foreign trademark and copyright authorities, tribunals, and courts, she knows how to navigate complex registration issues, defend her clients’ key assets, and handle enforcement issues in jurisdictions around the world.

In addition to filing and maintaining an extensive global docket of registrations, Marsha supervises enforcement actions, including proceedings before local trademark authorities, customs and court seizures, and civil and criminal counterfeit actions. Marsha works to keep her clients out of court, saving them time and money. She has been able to stave off copyright troll claims, and she convinced a well-known trademark holder not to sue and seek injunction against a cannabis company accused of infringement—all without the client paying a dime.

Marsha handles transaction and licensing negotiations and disputes with manufacturers, suppliers, and international distribution networks. She also oversees due diligence processes and is a mediator in the International Trademark Association’s select Trademark Mediators Network.

On top of her trademark and copyright registration practice, Marsha handles all manner of Internet and domain name controversies and proceedings, including UDRP proceedings, copyright “take down” notices, domain name transfers, social media, and internet registrar complaint procedures.

“The most solution-driven IP attorney I’ve ever worked with” is the highest compliment I’ve ever received. It’s exactly what motivates my approach to every client matter. ”
