I have a problem with a template I designed for cutting feathers.
I approached a "Friend" who had a laser cutter and asked him to make my design for me. He also sells his own products to the same industry that I do.
My template has different shapes on one side to enable me to cut different shaped feathers. There were about 6 shapes which also differed in length. He assured me he would not make them for anyone else. They sold very well

Imagine my surprise that they were my jig. Now there are some other jigs on the market that cut feathers but mine had a groove for locating the feather and another to trim it to a specific length, none of these other templates on the market have them so it is specific to my design. I approached the "Friend" and he said he hadn't made the same ones as he did for me, they were different shapes. I also told him I was designing some more shapes that he could make for me. (These shapes he produced before I gave them to him) The point is that they were my design and the design allows for different shapes thats the versatility about it.
He has owned up now that he shouldnt have done it and he was in the wrong and has recalled all the templates he supplied, except for 1 customer in The Netherlands who sent me an email telling me to "Piss Off", on 3 seperate emails. he continually posts pictures of them up on Facebook.
Question is,where do I stand and what can I do?
Any help would be gratefully received.
