Leo Boutsikaris' practice involves all phases of patent preparation and prosecution, including appellate practice before the United States Patent Trial and Appeal Board. Having worked as a patent examiner (becoming a primary examiner in 2005), he understands both sides of the patent prosecution process, and understands effective examiner interviewing strategies and prosecution procedures. Leo regularly conducts interviews with USPTO examiners in order to better understand the examiners’ positions and expediate the prosecution of applications while advancing his clients’ positions.

Leo has extensive experience in patent prosecution in high technology fields, including optical devices, lasers, optical waveguides, semiconductors, liquid crystal displays, optical sensors, medical devices and solar cells. He has also prosecuted patent applications related to printers and copiers, wireless networks, and computer games and systems. While at the USPTO, Leo examined applications in various classes, including classes related to optics-systems and elements, specifically optical holography, optical diffraction, light interference, and optical filters, optical fibers and waveguides and optical memories. Earlier in his career, he was a research scientist and deputy head of a research institute in Greece conducting basic and applied original research in areas such as dynamic holography and optical information processing and storage, and development of new optoelectronic materials. He has authored and co-authored a European patent (EP0737902A3), and scientific papers in prestigious scientific journals, including Optics Letters, Applied Optics, and Journal of Optical Society of America B.
