Prior to joining Edell, Shapiro & Finnan, Lawrence practiced patent law for over 10 years, initially at two patent boutique firms, and then at international law firms where he not only managed a sizeable patent prosecution docket, but also devoted a substantial amount of time to patent litigation including discovery matters, infringement and invalidity contentions, Markman claim construction hearings, depositions, and settlement negotiations.

Before embarking on a career in patent law, Lawrence worked as an electronics engineer building and testing high frequency, voltage- and temperature-controlled, crystal oscillators.  He later worked as a consultant at Booz·Allen & Hamilton where he was part of a team that managed the installation and integration of a terminal, high power amplifier, and a pair of satellite antennas on U.S. Navy ships. In this latter position, Lawrence developed a graphical software application to help identify optimal locations for the satellite antennas.  He also developed, and presented as a training tool, a graphical simulation of the operations of the terminal, including setting up and tearing down communications links and configuring communications resources.

In his free time, Lawrence enjoys playing music, reading, hiking, biking, camping, and skiing.
