Skimmed the patent. Its 99% a pedantic and exhaustive explanation of a linear motor. The only interesting thing they mention, is this:

The inertial mass of an object varies with the variation of its magnetic field and therefore a variation of inertia can be created

But they provide no explanation whatsoever for how a glorified linear motor is relativistically (or otherwise) affecting inertial mass. This could be operating under a novel application of ECE Theory, wherein they are using magnetism to affect gravity, but I doubt it. They would have claimed so.
