I believe you want to look into getting a patent as opposed to a copyright. Im thinking you might have a hard time doing this. Unless it has some very unique mechanics or something like that, you wont be able to get a patent on a lure that looks like a fish. Most lures are similar to another lure. I thought about getting a patent for the lure i created, but really its a similar concept to about a half dozen lures already made. And in the lure business, if you have a good idea, it will be stolen and mass produced usually by a bigger company no matter what you do. see senko or the paddle tail bass trix, huddelston.
