List of Edison patents

Below is a list of Edison patents. Thomas Edison was an inventor who, it is said, accumulated 1500-plus patents worldwide for his inventions. Nearly 1100 of Edison's patents were in the United States, but other patents were approved in countries around the globe.

Introduction

Edison is credited for contributing to various innovation, including the phonograph, the kinetoscope, the dictaphone, radio, the electric lamp (in particular the incandescent light bulb), the autographic printer, and the tattoo machine. Edison was a prolific inventor of his time and it is reported that he holds a record 1,093 American patents in his name. Most of these inventions were not completely original but improvements of earlier patents. Many of his patents were actually made by his employees - Edison patented their work and did not share the credit of the innovation.

American patents

First hundred patents

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. Jonas Aylsworth worked, from the opening in 1887 of Edison's labs, testing materials for phonograph recordings.

201 to 300

The next series of patents Edison received was mainly for the electrical distribution of power and the electric light. In 1883, Edward H. Johnson, a business associate of Edison, persuaded Frank J. Sprague to work for Edison. One of Sprague's significant contributions to the Edison Laboratory was the introduction of mathematical methods.

301 to 400

During the timeframe that the next few series of patents were obtained, the esteemed electrical engineer Nikola Tesla worked for Edison in America (beginning in 1884). When Tesla first arrived in the United States, he was offered a job by Edison when the latter saw his letter of recommendation from Charles Batchelor which read simply "I know two great men, and you are one of them. This young man is the other". Tesla's work for Edison began with simple electrical engineering. Eventually Tesla earned the respect of Edison and undertook a complete re-design of the Edison company's DC dynamos. Lewis Latimer also was under the employ of Edison companies (though never working with Edison).

Before losing the War of Currents, Edison continued to patent electrical distribution circuits and methods. He also continues to patent improvements in telegraphy, phonography, and lighting. Reginald Fessenden served as an electrician and a chemist for Edison. Fessenden left the Edison's lab around 1889. Arthur Edwin Kennelly contributed to a variety of Edison's endeavors undertaken to create a unique product or service from 1887 to 1893. Walter S. Mallory started working for Edison in 1888 (or 1889). Tesla was still working for Edison, but leaves before the end of this series of patents (ending his employ around 1886).

Design patents

Edison obtained a few design patents for the unique appearance and concept of items, giving Edison an industrial design right. His design patents are for phonograph cabinets and light bulbs with substantial decorative features.

Improvements

* 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)
* Nikola Tesla developed alternating current distribution, which could be used to transmit electricity over longer distance than Edison's direct current due to the ability to transform the voltage. It could be said that alternating current was not derivative of Edison's work, but it was related as were the two men. Tesla was a former employee of Edison, and left to follow his path with alternating current - which Edison did not support.
* 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.
