Lionel led us through the preparation, execution and the successful adjudication of our patents.  Securing a patent is a complex process; Lionel’s expertise in understanding abstract concepts and ideas and communicating them in the appropriate manner helped us succeed in this process. From filling out the paperwork to preparing for the in-person meetings, Lionel was an invaluable guide and advisor.” – Scott Dixon Smith, CEO, InQuisient
