Norman Dean was issued a patent for an inertial space drive in 1959.
There is no requirement that a patent actually work.

I have issues with these inventions.
First, PZT is not a metal and not capable of conducting; it is a piezoelectric ceramic dielectric. It needs a metallic coating to work. Second, if you do plate it with a metal to make a piezoelectric transducer, it has a high capacitance and will need lots of power.
“it appears the Navy relied on an affidavit from an expert, which the Examiner initially argued wasn’t sufficient ...”
How about the opinion of another expert in the field (me).

These inventions are flim-flam and won’t work.

Was this made by Andrea Rossi?!

Since 1952, the US has had on the books the Invention Secrecy Act that permits the federal government to keep a patent secret, even ones developed independently of government labs. As of 2017, there are almost six thousand such secret patents. With such a system of secrecy in place, I am hard put to imagine why these patents, if they represent genuine and practical innovations, would be applied for by the US Navy and permitted to become public.
I don’t understand any of it even with pictures, but I’m bookmarking it for possible future epiphany.
Captain Honor Harrington: To the bridge!
propagating gravitational field fluctuations are generated when the second electromagnetic field propagates through the first electromagnetic field.
All of this can be found in James Clerk Maxwell's original 200 field equations before they were butchered by Oliver Heaviside into only four vector equations.
Tesla used the original equations as best he could understand them to construct his devices and discover AC electricity.

THATS HEAVY.
I read about at least two of these about 12 years ago in an odd physics magazine I got at a local Barnes and Noble.
No problem, they will not work.
The thing doesn’t have to work in order to get a patent........................
