His patents extend from medical devices to computer software. Dr. Rassman founded the New Hair Institute (NHI) in 1991, and changed the Standard of Care in hair transplantation.

In 2003, he developed a patent for the hair transplant robot and licensed Restoration Robotics to build the ARTAS robotic hair transplant system. His recent interest extends into the field of biotechnology creating a ‘Lab-on-a-chip' the size of a Credit-Card capable of testing up to 1000 laboratory tests in under 15 minutes on a drop of blood.
