Nikola Tesla - Patents

Nikola Tesla filed his first patent application in the US patent office in March 1885.
After that, he continued to apply for patents, and was granted a total of 112 US patents, 17 British and 6 Canadian patents.
The content provides an overview of Tesla's patents according to the dates of their application in the patent offices. This chronological presentation shows the dynamics of Tesla's work, which is reflected through patent applications, and also an overview of the technical areas that occupied him over the years.
Many of Tesla's inventions that he invented before leaving for the USA are not protected by a patent, as well as inventions for which Tesla, due to a combination of circumstances, did not request the right to a patent.
