Or it may be evidence of prior art or there may be a prior patent, meaning that VirTra's patent could be invalid or VirTra may be infringing. StressVest claims on their website to have a US patent for the vest, but they don't give a patent number, and I couldn't find it; maybe someone with better search skills than me can locate it. They also claim other patents, but don't supply patent numbers, which is odd.

Actually, I'm not sure why the previous existence of dog training shock collars does not make VirTra's patent invalid in the first place, but I know enough about patents to know that common sense doesn't enter into it.
