Richard Mandaro litigates patent, trademark, copyright, trade secret, and unfair competition cases in the leading intellectual property litigation venues, including the Southern District of New York, the Eastern District of Texas, and the Northern and Central Districts of California. In addition to litigation, Rich counsels his clients regarding the development, protection, and commercialization of their intellectual property.

With a background in electrical engineering, Rich has worked on patent cases involving consumer electronics, semiconductors, computer and Internet technologies, camcorders, plasma and LCD televisions, sensors, and telecommunications devices. Rich also litigates trademark and copyright cases, most recently in the Vans, Inc. v. Walmart, Inc. case, Macy's IP Holdings, LLC v. Aroma360, LLC case, and Benefit Cosmetics LLC v. e.l.f. Cosmetics case.

Rich counsels companies in the technology, retail, apparel, cosmetics, toy, and restaurant businesses, among others, on trademark and brand development, protection, enforcement, and anti-counterfeiting. Rich’s clients range from large Fortune 500 companies to start-ups. He understands the need to achieve a client’s business objectives without litigation whenever possible and has extensive experience resolving matters through negotiation, mediation, alternative dispute resolution, and strategic licensing.

As a litigator, Rich is always aware of the business context and economics of disputes, and clients’ expectations for a practical, economic, and strategic approach. With a wealth of experience in both small and large-scale enterprises, Rich is well-positioned to assist clients from diverse business perspectives. When not practicing law, Rich expresses his entrepreneurial passion by running and operating his own successful gourmet hot sauce business.

Rich acts as local counsel in the New York District Courts for out-of-state attorneys who seek insight into local judges and their practices and procedures.

Rich has served on the executive alumni board for his law school and is active in numerous professional associations outside of his law practice.
