Over 300 patent applications were made by the prolific inventor Nikola Tesla during his lifetime, spanning a variety of industries and technologies. Some of his most notable patents are listed below:

Tesla's most important invention, the AC electrical system, which he created in the late 1880s, is a modern-day version of that. This technique, which made it possible to transmit electrical power over great distances, eventually became the norm for doing so worldwide.

Tesla coil: A resonant transformer circuit that generates high-voltage, low-current, high-frequency alternating current is known as a Tesla coil. The Tesla coil, which Tesla developed in 1891, is being utilized in a number of fields today, including radio and television technologies.

Alternating current motor: In 1887, Tesla created an AC motor that was more effective than the DC motors that were already in use. This innovation paved the door for AC electrical systems to be widely used.

Tesla envisioned a wireless communication system that would enable individuals to connect with one another and access information from any location on Earth. In 1900, he submitted a patent application for a wireless communication system, which established the foundation for contemporary wireless communication technology.

Tesla's bladeless turbine is a sort of rotary engine that produces energy without the usage of blades. He obtained a patent for the turbine in 1913, and a number of uses, including wind turbines, have subsequently been made possible.
A radio-controlled watercraft was displayed by Nikola Tesla in 1898; he termed it the "teleautomaton." It is one of the earliest examples of remote-controlled cars, and he applied for a patent for it in 1900.

X-ray imaging: Tesla started working with X-rays in 1897 and submitted a patent application for a machine that could generate images using X-rays. Although he did not advance the technology, his work helped to pave the way for X-ray imaging technology.

Nikola Tesla's ideas and discoveries continue to influence and inspire new generations of scientists and inventors. His patents covered a wide range of technologies and fields. His legacy is proof of the brilliance of human intellect and the ability of innovation to influence the future.
