I know the pony/horse head jig heads are all patented, not gonna mess with them unless I decide I want them for myself

Are any of the others patented? The pillhead underspin, the stump thumper and any others so I know which ones not to get if I want to make and sell them somewhere down the road.

I did a search, I swear, and I all I got was that the pony/horse head was patented.
