Richard Mandaro litigates patent, trademark, copyright, trade secret and unfair competition cases in some of the leading intellectual property litigation venues, including the Southern District of New York, Eastern District of Texas and the Northern and Central Districts of California.

His clients range from large Fortune 500 companies to smaller companies, including start-ups. In additional to litigation, he counsels his clients regarding the development, protection and commercialization of their intellectual property.

With a background in electrical engineering, Mr. Mandaro has worked on patent cases involving consumer electronics, semiconductors, computer and Internet technologies, camcorders, plasma and LCD televisions, sensors and telecommunications devices. Mr. Mandaro was selected as liaison counsel for a defendant group in the largest multi-district patent litigation case in which Ronald A. Katz Technology Licensing asserted a portfolio of more than 50 patents primarily in the field of automated call center technology.

He is a member of numerous joint defense groups in high-profile patent cases. Mr. Mandaro also acts as local counsel in the New York District Courts for out-of-state attorneys who seek insight into local judges and their practices.

As a litigator, he is keenly aware of the business context and economics of disputes, and clients’ expectations for a practical, economical and strategic approach. In numerous cases he has achieved dismissal following successful Markman rulings. He is proactive in seeking indemnification from vendors that provide systems and services that are the subject of patent infringement allegations, and seeks to enforce a vendor’s duty to defend and pay for litigation costs.

Mr. Mandaro also counsels companies in the technology, retail, apparel, toy and restaurant businesses, among others, on trademark and brand development, protection, enforcement and anti-counterfeiting. 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 business arrangements such as trade credits, offsets and strategic licensing.

Another aspect of his practice involves due diligence searches and valuation of intellectual property for financial services companies.

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