Antonio Papageorgiou specializes in preparing and prosecuting patent and trademark applications, and rendering non-infringement and freedom to operate opinions in a broad range of technology, including software, business methods, and electrical/mechanical devices and systems. Before starting his own practice, Antonio was in-house counsel for Cantor Fitzgerald L.P. where he evaluated Cantor’s portfolio of issued patents and patent applications for potential licensing value, technical merit, and patentability/validity. He also reviewed and evaluated work performed by outside counsel and in-house patent and trademark attorneys, and he established a cost effective patent strategy that resulted in a substantial increase in the number of patent applications filed and more importantly in the number of patents granted.

In addition to oversight responsibilities, Antonio prepared and prosecuted applications directed at some of the firm’s “key” technologies, which included appealing a number of patent applications to the Board of Appeals of the U.S. Patent and Trademark Office. He also prepared and negotiated various types of agreements, including software and IP licenses, merger and acquisition agreements, master service agreements and joint development agreements, he performed due diligence on various corporate and IP acquisitions, and he advised executives on patent litigation issues, including those in a case appealed to the Federal Circuit (eSpeed, Inc. v.Brokertec USA, L.L.C., 480 F.3d 1129 (Fed. Cir. 2007)).

Prior to his in-house experience, Antonio was an associate at the prominent New York law firms Frommer Lawrence & Haug LLP and Brown Raysman Millstein Felder & Steiner, LLP, where he prepared validity, infringement, and right to use opinions, motions for patent interferences, and briefs for patent litigation, and where he prosecuted patents in the software, business method, electrical, and mechanical arts.

Before becoming an attorney, Antonio was an engineer for the Federal Aviation Administration where he designed and supervised installation of systems and facilities that supported air traffic control, including UHF, VHF, and microwave communication systems, instrument and visual landing systems, RADAR systems, middle and outer markers, approach lighting, and facility power and mechanical systems.  Antonio’s work extends throughout the FAA’s Eastern Region, including at the New York TRACON (Terminal Radar Approach Control), the Islip and Leesburg ARTCCs (Air Route Traffic Control Centers), and several control towers in the Eastern Region, such as LaGuardia (LGA), Washington National (DCA), and Newark (EWR) towers.

Antonio received his JD degree from St. John’s University School of Law. In addition to other distinctions, Antonio graduated cum laude, in the top 10% of his class and served on the St. John’s Law Review.  Antonio received his engineering degree from the City College of New York.

Antonio is licensed to practice in New York and before the US Patent and Trademark Office.
