They STILL don't comprehend what validity means even tho it's been explained many times.

Does a patent application have to prove its efficacy?

No, an inventor doesn't need to prove that an invention works to get a patent. Instead, they only need to show that they had the idea. However, the United States Patent and Trademark Office (USPTO) may request a working model if the invention is novel, non-obvious, or defies expectations. A working model can strengthen a patent claim and increase the chances of making money.

Do you have to prove something works to patent it?
An inventor need only show that he or she had the idea; the discovery that an invention is reduced to practice (i.e., actually works) is not required to prove the date or content of the invention.
