Fross Zelnick Lehrman & Zissu, P.C. was founded in 1969 by leading New York lawyers who quickly acquired a clientele of prominent US and foreign trademark owners, establishing the firm as a leader in the intellectual property (IP) field.

According to surveys of in-house and external counsel in the intellectual property field, Fross Zelnick is considered one of the premier firms in the world for trademark, copyright, design patent, and unfair competition law and, with approximately 50 lawyers, is probably the largest law firm dealing exclusively with this area.

Main areas of practice

Defending IP rights: Fross Zelnick is a leading trademark and copyright litigation firm in the US with a reputation for successful litigation that often leads to settling disputes without court proceedings. When necessary, Fross Zelnick lawyers argue cases in federal and state courts, and opposition and cancellation proceedings in the US Patent and Trademark Office (USPTO), and act for clients in arbitrations and mediations. Internationally, the firm’s wide experience in foreign and multi-country trademark and copyright litigation includes a history of successfully recapturing pirated well-known marks.

Registering trademarks, copyrights, and design patents: the firm’s lawyers are highly knowledgeable about US and foreign trademark, copyright, and design patent laws, enabling them to obtain rights that will stand up in court. Fross Zelnick is consistently among the top filers of US trademark applications, and has been honored by the USPTO for being the top filer of electronic trademark applications.

Combating counterfeiting: Fross Zelnick’s lawyers have extensive experience with anti-counterfeiting and enforcement matters. The firm has developed sophisticated and cost-effective enforcement programs for its clients to prevent the importation, sale, and distribution of a wide variety of infringing or counterfeit products, including apparel, footwear, cosmetics, jewelry, and luxury goods.

Managing global portfolios: Fross Zelnick is known for providing exceptional global IP management. Working closely with its select network of foreign counsel, the firm develops and executes winning strategies to identify, protect, and defend their clients’ intellectual property rights under trademark, copyright, trade dress, design patent, trade secret, and related laws in the US and throughout the world.

Negotiating IP transactions: whether clients are buying or selling an entire business or part of a portfolio, Fross Zelnick negotiates assignments, licenses, and related agreements to safeguard its clients’ business and legal interests.

Protecting characters and celebrities: for decades, Fross Zelnick lawyers have protected famous entertainment characters through sophisticated copyright protection strategies and enforcement against infringers. They also have retrieved numerous infringing or disparaging trademarks and domain names for celebrities and litigated high-profile cases involving the unauthorized use of well-known names and likenesses.

Conquering the internet: internet law is evolving as rapidly as the medium itself and much of it is rooted in trademark and copyright law. Fross Zelnick’s lawyers litigate uniform dispute resolution proceedings (UDRPs) against cybersquatters, advise on worldwide domain name registration and disputes, monitor the web for infringements, negotiate linking and key word agreements, draft privacy policies, and develop strategies for policing and protecting IP rights on the internet.
