Patent application on the QUANTUM SPACE ENGINE (EM drive)
A story on the patent application for the EM drive contains the following text:
“The patent process is a very significant process, it’s not like an academic peer review where everyone hides behind an anonymous review, it’s all out in the open,” Shawer told Marry-Ann Russon at the International Business Times.
He went on to say that “this is a proper, professional way of establishing prior ownership done by professionals in the patent office, and in order to publish my patent application, they had to first carry out a thorough examination of the physics in order to establish that the invention does not contravene the laws of physics.”
Elsewhere in the post is a reference to SWAS:
The program delaying patent applications is called the Sensitive Application Warning System (SWAS). Usually, when an application is submitted for a patent approval, it requires a couple of examiners who work with the Patent office to go through their process of approval. This process usually takes approximately 1 to 2 years, but applications that are filed in SAWS must be approved by several people, and can be delayed for a number of years.
One great example (out of many) of delayed patent applications comes from Dr. Gerald F. Ross. He filed a patent application for a new invention he had devised to defeat the jamming of electromagnetic transmissions at specified frequencies. It was not until June 17, 2014 (almost 37 years later) that this patent was granted (source).
