Those are all terrific links to U.S. government websites, not taking into consideration that the laws are interpreted in the courts, and not taking into consideration that these U.S. sites will not necessarily answer questions posed by someone in another part of the world.
That said, if you wish to use rights-protected material, you will generally in all parts of the world need to obtain a license to use the material, the license granted by the holder of the rights. For example, here is a link on how to obtain a license to use the Mossy Oak Camo Pattern:

And here is a case out of Texas from this year over design patent infringement and trademark infringement, that could be of interest if you are in the U.S. (
Kryptek Outdoor Group, LLC v. Salt Armour, Inc.):

If you could provide the name of your state or, if not in the U.S., the name of your country, I can perhaps direct you to what on the sites provided above you should look at (if applicable) and how the laws have been interpreted by the courts, and I can probably provide you with some easy-to-digest information on the rights that protect some (but not all) patterns.
Thanks.
