Andrew has experience identifying and protecting inventions across a wide spectrum of industries and technologies, including:

  • Medical devices (e.g., dialysis machines, injectors, and surgical implants)
  • Automotive ( e.g., engines, igniters, and control systems)
  • Energy (e.g., solar, geothermal, and nuclear systems)

Prior to joining Nutter, Andrew was an associate at an intellectual property boutique. Before studying law, he was a research assistant at the University of Cincinnati, where he developed noise reduction technologies for use on commercial and military jet engines. Andrew designed and implemented an experimental model at the University’s Aeroacoustic Test Facility to study the fluid and acoustic effects generated by the asymmetries in a commercial engine’s exhaust flow. Andrew’s thesis was titled Experimental Study of the Flow and Acoustic Characteristics of a High-Bypass Coaxial Nozzle with Pylon Bifurcations and his research validated the experimental model against large-scale testing facilities at NASA, GE, and Boeing.

In law school, Andrew served as editor-in-chief of Boston College Law School’s Intellectual Property Law & Technology Forum.
