Newman"s Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine.United States district court requested that Newman"s machine be tested by the National Bureau of Standards (NBS). The NBS concluded in June 1986 that output power was not greater than the input.pseudoscientific and his claims as false.

In 1979, Newman submitted an application for his device to the United States Patent and Trademark Office.United States District Court requested a master of the court to make the final decision. William E. Schuyler, Jr, former Commissioner of U.S. Patent Office, Washington, DC was chosen by the court to make the final decision to award the patent or not award the patent to Newman. Schuyler concluded that evidence to support Newman"s claim was overwhelming and found no contradictory factual evidence.

However, the judge ordered Newman"s machine to be tested by the National Bureau of Standards (NBS). The National Bureau of Standards (NBS), now known as the National Institute of Standards and Technology (NIST), by request of the patent office, tested the device for several months and got negative results. In every case presented in the NBS report, the output power was less than power input from the battery pack, and therefore the efficiency was less than 100%. The court therefore upheld the rejection of the patent application.

Joseph Westley Newman (July 2, 1936 – March 6, 2015) was an American inventor and author who developed an "energy machine" deemed by the US Patent and Trademark Office to be a perpetual motion machine. He described this device in a book, Albert Einstein"s unified field theory of physics. After applying for patents on the perpetual motion motor, he battled for over seven years against what he claimed was a government conspiracy to suppress his supposed discoveries,

Joseph Newman applied for a patent on his "energy machine" in 1979, which was rejected by the US Patent and Trademark Office as a perpetual motion machine. From 1979 to 1986 he filed lawsuits against the patent office to force the award of his patent.
