But what if there isn't any visual difference between YOUR product and THIER product? There is no problem with improving a design until it isn't recognizable anymore, but that's not what this thread is about.
Jeep is suing Humvie right now, because the grill looks too similar to the deisgn of the Jeeps front grill. You can't splash a car or a coke -- a splash is made from a direct molding technique -- When you pop a hull its an exact image of the first. The coke bottle and recipe are both very much protected.
Sometimes the splashers claim there are some 'changes' in the hull. Many of them do make serious changes, but the splashes being done with our boats have such slight chages you can barely find them. Some have no change at all.
We got a call one time from some friends, congratulating us on our boat being in the new Mercury brochure -- when I saw it I even thought it was our boat!
It looked *exactly* the same, perfect mirror image to our boat, but it wasn't ours! It was a total splash.
Puder was right on when he said, if you think you can make improvements on an existing hull then do it the legit way -- buy the molds or design rights from the owner and go for it! And that's precisely what the guy did who purchased our company.
It is wrong to simply pop the designs and start calling them your own.
