The patent you’ve referenced, US10144532B2, titled “Craft using an inertial mass reduction device,” was granted to the U.S. Navy and describes a theoretical spacecraft design that aims to reduce its inertial mass, potentially allowing for high-speed travel. The concept involves a resonant cavity with inner and outer walls, where microwave emitters generate high-frequency electromagnetic waves within the cavity. The interaction of these waves is proposed to create a net directional force, potentially reducing the craft’s inertia and enabling rapid movement. 
It’s important to note that this patent represents a theoretical concept. As of now, there is no publicly available experimental evidence demonstrating the practical feasibility of such a device. The scientific community remains skeptical, and further research would be necessary to validate the principles described in the patent.
