A patent is only given for a new and useful process/method, machine, or composition of matter, or significantly new and useful improvement of these things.
Of course, no one would expect that you would need a stable ground state in order to detect variations from that ground state ...
Except that patents actually stick around for decades, generations, or even centuries now, giving a corporation a permanent monopoly on technology, because a competitor can't use the same process even if they figure out how to do it, and even if it's the best thing available within the known laws of physics. This means competitors are required to use inferior technology, forever, even if they know how to make the patented, more advanced technology. This is NOT what was intended by patent laws.
