VirTra Inc (VTSI)

[jmodified]

OK, the StressVest patent is #7872849. It was filed after the initial VirTra Threat-Fire filing. It was also disclosed for consideration by VirTra to the USPTO, and is referenced in the Threat-Fire patent, so VirTra is well aware of it, the patent examiners were well aware of it, and there should be no issues with infringement either way.

If you read VirTra's patent, it is clear that what they are patenting is "a method of training" using the belt, not the belt itself. Typical patent mumbo-jumbo, but that is how the system works.
