Some do, most do not. Usually a patent covers a part of a bait. For example, Strike king has a patent on their Rage Tail. It goes on to detail what qualifies as a rage tail...
I try to avoid everyone's intellectual property, protected or not. It's a decision we made when we started.
The part I enjoy most about Caney Creek is the design aspect. We live and work on a great lake. I love testing baits, observing the fish and their forage, spending quality time on the water, just taking it all in. I love it.
I also think it's cool that we (collectively all of us) can make baits that outperform huge companies and all their money. Fishing and making baits is a level playing field where any one of us can go out and on any given cast anything could happen. I think that is very cool.
A little more info than was probably needed - I just get excited.
Tight lines!
