Luck, Timing, Hard Work and Perserverance (spelling) ...
Patents -- Design, Mechanical & etc ... take time & money ... and most of the time one little change is all it takes to get around it ... now registering the name is the only solid way to identify YOUR product in the world of lures .... one company with distribution all ready in place can wipe you out ... been there had it done to me ( I made a few mistakes as well) ....
Its your shot ...
GOOD LUCK
