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.
Antonio is a partner at Lombard Geliebter. Before joining Lombard Geliebter, Antonio was a partner at Meister Seelig & Fein LLP. Prior to that, he was in-house patent 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 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.
At Cantor 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, he performed due diligence on various corporate and IP acquisitions, and he advised executives on patent litigation issues, including issues 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.
