Converting a brooch is not a new idea. No theft on RQ side. Looks like he just figured how to make it better.

I view this as a basic piece. So to go to what I know, piercings.

1 company makes single point implant feet. They are kind of ok, but room to improve. Company does care to improve.

Another company gets requests, figures how to make superior feet. They do so. They aren't cloning the first.

They are meeting the laws of supply and demand. There is a demand for an improved foot with no supply. Anyone can fill that supply.
