It’s South  Korean, but not sure if that’s where the parents are. The EXT1&2 use different tech than the Reference and the plus. I believe they are using a magnetic field in the Ref unit, but yes they are vague. Whatever it is, it sure works and it lowers the noise floor lower than any of the other boxes I’ve tried as well as the optical isolators I’ve tried 

Well the whole point of patents, at least in the US, is that the patent grantee is given a limited monopoly on using the invention in exchange for publishing details of the technical advancement so that everybody can learn from it.  Generally, saying that you have a patent on an invention or that one is pending is frowned upon by the law, unless either one is actually true.  No idea about South Korea on that.

If you want to keep something a secret, that's different.

I would think that SK would be closer to US law than DPRK or China.
