Either the patents have run out, or they're assuming CAT won't bother to sue them. You can make an exact copy of anything as long as you don't get so close in appearance you're taking advantage of someone's branding, or infringing on patents. In the case of patents the burden of proof is on the patent holder and I would guess you would have a separate suit for each patent, and then there's the problem of where do you have to file the suit, Mexico, China, ???

What specific patents are being violated ?

Read a patent carefully.

Maybe a design patent ? basing on the outward appeance and style ?

It looks like a mix of old and new technology. It is easier to spot the weak points than it is to see the benefit stuff. That Chinese video was terrible.:cool2

Funny you should mention that Richard.. just the other day I had a pump come in the shop.. the name plate was torn off of it but the rivets were still there.?? so SOMEONE HAD TO RIP the np off..
after further inspection of the P#'s of the components inside the pump and getting a SN from the customer.. it WAS INDEED a Chinese BUILT CUMMINS MOTOR..
I guess if the "BIG GREEN" company can do it with their Yanmars.. why not "THE BEIGE".??? I never thought I would see the day..

A utility patent is only good for twenty years if you pay the government on time. A design patent is good for fourteen years. I can't see how there are any pending patents on a high drive dozer since the concept has been around for at least forty years. Also Cummins have been licensing their manufacturing out of the US since at least the seventies.

A Trademark is good for a long as the owning company maintains it. I believe Cat's trademark will be maintained ferociously as long as the world turns. I doubt you will ever see one of those clones with any type of graphic or symbol that remotely looks like something Cat might have have had something to do with.

A Copyright is good for the life of the creator plus 70 years after the death of the creator. Software designers are trying to apply this to everything. Seems to be the claim by Deere about only their service people can repair one of their brand of tractors.

Manufacturers in China still think it is clever to profit on the labor and investments of others. Then again they are only trying to follow in the foot steps of the Japanese. I can also say that the people at Caterpillar are not entirely blameless in that regard either.

Wonder if it takes a CAT key? Also wonder if Cat has something to do with it or are receiving monies from it.

My thoughts as well . I actually like the idea of it , Old school big cam cummins powered 25 ton dozer with a modern look about it .

I also like the looks of the Shantui dozers , they use the old big cam cummins as well . http://en.shantui.com/products/sd22.htm

Cat wasn't even the first one to manufacture high drives. Cletrac made some small machines with high drive back before WW2.

The power plant irony isn't lost at all, how about a TD 15 clone with a John Deere engine or Terex clone with a Cummins in it.
These sound like something I would do, well let's see here, I have a dozer and I have a random engine lets put it together!
