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 lain 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.
In the book Tesla: Man Out of Time, there are references to missing patents. Some patents of his experiments are lost to history, as well as some of the scientific notes and records pertaining to Tesla's patents. These, though, are alluded to in the redacted FBI files. The missing patents may be among effects seized by government agents and military intelligence officers following Tesla's death in 1943. In various patent logs, it is recorded Tesla received U.S. Patent 613,819 for "Filings Tube" (such as Charles Henry Sewall's "Wireless Telegraphy" (New York, 1904)). This number does not match the U. S. Patent office records (that patent is issued to G. Kelly for an "Illuminating torch").
The following is a list of other countries that hold known patents by Tesla. The number following the country is the number of known patents in their records. This is not an exhaustive list. The total number may be incomplete and additional countries still may hold patents unknown.
Devices and projects Tesla proposed and partially designed but did not patent.
