John is a partner at Bingham Greenebaum Doll LLP. He practiced professionally as an engineer and program manager for the first 20 years of his career, and as a patent attorney for the next 20 years of his career. This background provides him a unique opportunity to apply industry-used principles of project management to legal projects.  John has been named an IP Star every year since the award started.

He focuses his legal practice on patent opinions (including freedom to operate, infringement, designing around, and patentability), and patent prosecution and licensing in a wide variety of mechanical and electrical fields. He has also advised in litigation pertaining to patent, trade secret, and patent malpractice. He has helped clients protect inventions pertaining to medical devices, nanotechnology, various types of engines (including jet, rocket and diesel), sensors, signal processing and dynamics, vehicles, food packaging, manufacturing, fluid manipulation, and non-lethal weapons.

John obtained over 20 years of engineering experience, primarily in aerospace, with Hughes Aircraft Company, Missile Systems Group; General Motors, Allison Division, Advanced Military Engines; and Chrysler Corporation. As an engineer his experience includes being an analyst, design engineer, systems engineer, engineering supervisor and chief project engineer. His technical experience includes analysis, testing, design and engineering management of missile guidance units, computer control systems for aircraft and automotive engines, jet engine hot sections and automatic transmissions. He has applied his skills to the AIM-120 AMRAAM air-to-air missile, the YF-23 stealth fighter, the V-22 Osprey and the E-2C Hawkeye programs.

John became an attorney in 1995. For 10 years prior to joining BGD he practiced patent law at an IP boutique law firm in Indianapolis, where he was a partner and Chairman of that firm's Patent Group. At Purdue University in West Lafayette he performed graduate research in computer modeling, application of optimization theory, and emissions testing of internal combustion engines, and also taught classes in instrumentation. He obtained a license as a Registered Professional Engineer in the state of Indiana.
