It would be fairly easy though to argue that the shape of a knife is a necessary component of its performance and therefore of a patent. A shape of a knife directly effects is cutting performance and overall durability. I don't think that would be hard to prove. After all, the main differences of a knives true performance related to its intended use (i.e. to cut things) is in the blade shape.
Your opinion about the ease of getting a patent on a knife shape doesn't jive with the reality of patents. Demonstrating a scientific correlation between performance and a device that consists of blade + handle is pretty much impossible. A patent must show how the device brings something new to the table. That's why ZT, Kershaw, etc don't have patents on knife shapes.

What leads you to that bizarre conclusion? There's no difference in law - which is the one and only point I was making. I didn't express any feelings about my "book".
B34Ns said:Not sure how long you've been away from the internet, but KIA has had licensing to manufacture for a while now. Only a few models come off the line where the willy's were produced anymore. They don't have to copy, it's called licensing.
You can license a product, or reproduce all the non-protected elements of a product without licensing. Both are done all the time. There are advantages/disadvantages to both. Licensed products come with complete specs and blueprints - sometimes even tooling. Copies have to be reverse engineered.
What does that have to do with the internet?
I think you misread what I wrote, because it sounds like you're objecting. I agree that you can't trademark, copyright or patent old patterns. (Unless they're DNA.)B34Ns said:you can't trademark a thousands year old pattern. Otherwise musems would be raking in the dough. try again. Try it with tech at any scale and watch the lawyers eat you for breakfast. Let's be real.
I really don't understand either of your posts.
