Report on the Readiness of Perpetual Motion

2017-08-17—I would say perpetual motion is anywhere between Level 1/9 and Level 8/9 right now, due to the simplicity of the technology.

ADDITIONAL STATISTICS:
People interested in perpetual motion tend to be males 19 to 45 years old. They may be relatives of engineers, and/or good with their hands, and/or interested in clean energy.

NOTES AT STACKEXCHANGE:

I'm still not sure I really follow. The notability or importance of an invention is really orthogonal as to whether it can be patented. The patent office does not exist to give publicity to inventions per se (at least, not beyond the duty of disclosure that all patent applicants have), but merely to decide what inventions should receive a patent. —Maca (2018 / 03 / 05)

On a second look, I can see now that your question is how to publicise your invention if people don't believe in it. This is a problem that lots of inventions have: especially pharmaceuticals. How does one prove new drug X cures disease Y? By solid theory and rigorous empirical tests. But that is somewhat outside the scope of this stack, since we only deal with patents, and not commercialisation. —Maca (2018 / 03 / 05)

How Can I Patent My Perpetual Motion Machine? One requirement for a patent to be granted is that the invention is useful (35 USC § 101). Since perpetual motion machines are inconsistent with modern laws of physics, it is assumed that a patent application relating to a perpetual motion machine does not function, and therefore is not useful. The application is therefore summarily rejected.

However, if the applicant can show a working model to the examiner, this assumption can be overcome. In such a case, the application can proceed as with any other kind of invention.
