While their description claims that there is no reaction mass pushing on, this does not mean that it is the correct explanation if their device would work.
The device might not work far from the Earth, but only in the neighbourhood of other bodies, due to some kind of interaction with them.
Moreover, while around the beginning of the 20th century it has become fashionable to rebrand what was called previously "aether" as "vacuum", this change of name has been just a useless cosmetic change.
The mathematical description of vacuum has remained the same as that of the aether as conceived by Maxwell and the other physicists who opposed the theories based on action at a distance, i.e. the vacuum is something that mediates the interaction between bodies. Regardless whether it is called aether, vacuum or electromagnetic field, in most theories it is endowed with properties like energy and momentum.
So it could happen that there would be a way for a device to push on the ubiquitous electromagnetic field.
This device may be a hoax or a honest mistake, but the current theories of physics are much farther from being completed than most people believe.
Much of the physics taught in school is full of junk that is more definitely wrong than the claims of this patent.
For example, the so-called Lorentz force, which is taught as the way how the electromagnetic interaction happens, does not satisfy Newton's law of action and reaction, so it also does not push on what it should push. (When the Lorentz force is integrated over closed loops, it gives correct total results, but when the forces that act on parts of the circuits are computed, the actions and reactions are not equal.)
Only the Ampere force, which nobody learns, has a form that is compatible with Newton's laws.
