List of Edison patents

Below is a list of Edison patents. Thomas Edison was an inventor who accumulated 2,332^[1] patents worldwide for his inventions. 1,093 of Edison's patents were in the United States, but other patents were approved in countries around the globe.

Edison is credited for contributing to various inventions, including the phonograph, the kinetoscope, the dictaphone, the electric lamp (in particular the incandescent light bulb), and the autographic printer. He also greatly improved the telephone by inventing the carbon microphone. Most of these inventions were not completely original but improvements of earlier inventions. However, one of Edison's major innovations was the first industrial research and development lab, which was built in Menlo Park and West Orange.

Throughout the 20th century, Edison was the world's most prolific inventor. At the beginning of the century, he held 736 U.S. patents. His final count was 1,093 U.S. patents, including 1084 utility patents (patents for inventions) and 9 artistic design patents. It was not until June 17, 2003 that he was passed by Japanese inventor Shunpei Yamazaki.^[2] Yamazaki was subsequently passed by Australian inventor Kia Silverbrook on February 26, 2008.^[3]

The first hundred patents mainly deal with the telegraph system. John Kruesi was the shop manager beginning in 1872. Kruesi built models, instruments, and apparatus for Edison's work. John Ott worked with Edison throughout his career. Ott was Edison's main model and instrument maker. Charles Batchelor was a superintendent for Edison toward the end of this series of patents.

• Lewis Latimer patented an improved method of producing the filament in light bulbs (there is no evidence that this was ever used by an Edison company)
• Emile Berliner developed the gramophone, which is essentially an improved phonograph, with the main difference being the use of flat records with spiral grooves.
• Edward H. Johnson had light bulbs specially made, hand-wired, and displayed at his home on Fifth Avenue in New York City on the first electrically-illuminated Christmas tree on December 22, 1882.

• Phonograph
• Incandescent light bulb
• Electric locomotive
• Kinetoscope
