Soild-tech are one of the pioneers (1995), I don't believe they copied anyone. Years ago when we were searching for isolation devices for loudspeakers, Solid-tech of Sweden and Townshend of UK (1987) were the main two to be found on the internet.
Solid-tech doesn't appear to use similar technology or use of springs in the same manner Townshend does?
I see many knock-offs now coming from newcomers though.
