A note of clarification. I can't claim ownership of the grill. That is ambiguous. I worked with them and guided the development of a grill they had earlier developed that did not fit well. There were no drawings or dimensions done, we simply modified and eventually got the fit we wanted. The verbal understanding we had was that I would have the right to market exclusively, then he started increasing the prices. In a very short time, he increased my prices to about what he is now charging to sell the grill to the public. I don't think I have any basis to try to restrict his sale of the grills, but I DO OBJECT TO HIM USING MY COPYRIGHGTED PHOTOS TO MARKET THE GRILLS. I can't believe that eBay has not even responded to my complaint regarding this.
