Excerpt: Below is a list of Tesla patents. Nikola Tesla was an inventor who obtained around 300 patents worldwide for his inventions. Some of Tesla's patents are not accounted for, and various sources have discovered some that have laid hidden in patent archives. There are a minimum of 278 patents issued to Tesla in 26 countries that have been accounted for. Many of Tesla's patents were in the United States, Britain, and Canada, but many other patents were approved in countries around the globe. Many inventions developed by Tesla were not put into patent protection. The "Bladeless" turbine design, Tesla's 100th American patent.Tesla's inventions and developments include the AC motor, the bifilar coil, various devices that use rotating magnetic fields, the alternating current polyphase power distribution system, the fundamental devices of systems of wireless communication (legal priority for the invention of radio), radio frequency oscillators, devices for voltage magnification by standing waves, robotics, logic gates for secure radio frequency communications, devices for x-rays, apparatus for ozone generation, devices for ionized gases, devices for high field emission, devices for charged particle beams, methods for providing extremely low level of resistance to the passage of electrical current, means for increasing the intensity of electrical oscillations, voltage multiplication circuitry, devices for high voltage discharges, devices for lightning protection, the bladeless turbine, and VTOL aircraft. Recent references to Tesla's patents include US5548819 (Method and apparatus for communication of information), US5908444 (Complex frequency pulsed electromagnetic generator and method of use), US4869598 (Temperature-sensitive multiple-layer thin film superconducting device), and US6104107 (Method and apparatus for single line electrical transmission). In the book Tesla: Man Out of Time, there are references to missing patents. Some patents of his experiments are lost to histo
