The original Wankel and NSU patents have only been licensed to Mazda. The Wankel-patents are all in a society. This was sold by Felix Wankel a few years before he died. The company who bought it did not do anything with it. It has now been moved on, and into a new society. Don't know the name though.
The Wankel engine can now be build by anyone, but Mazda has the rights to most of the emmision systems, and also to some types of seals and materials.
The engine design for sale, does not really look that revolutionary to me. Felix Wankels experiments included some things that were rather simular...
Since it's up for sale for $500 start price, I'd think there's a problem there. I mean: a really good engine design can make you RICH.

Every corporation that seeks to manufacture the KKM rotary has to buy the rights from NSU. Benz had to do this, GM had to do this, Curtis-Wright had to do this, etc., etc; "borrowing" the rights to the design of sorts.
I believe NSU still holds ownership of the KKM.
It's been a while since I've looked at this stuff so someone feel free to chime in if I'm off base.
If anyone is interested in the history, design and any other topic you can think of, check out http://www.monito.com. Whomever built that site is great. I've gotten more useful and obscure information off of that site than any other.

all manufacturers that experimented with the KKM had to buy the licenses from NSU-Wankel, and most of them had a limitation in some way. But the rights indeed will be with NSU, now part of the VW-Audi group. I was talking about the many other patents (mostly rotary related) Felix Wankel owned himself, and those were all sold. Wankel himself also had the right to produce KKM Wankel-engines, and did so in his company "Wankel GmbH", which still excists. Since this has been in a sort of trust, has been sold and then again sold (now in a trust again) those owners do have the rigt to build KKM engines, without paying NSU. However, to be able to construct a decent one, they'd probable need a lot of ideas Mazda has incorporated in the KKM, and Mazda has patented those. So to make a decent Rotary Engine, one would probable have to pay Mazda.
If I'm not mistaking, the early patents are now free to public use, and no longer protected. So everyone could build a KKM, but again: all sorts of things are protected by Mazda copyrights...

You'd be surprised at the number of things car manufacturers DON'T patent.
When you patent something you have to detail every part and how it works, making it easy for your competition to look up and make a change to defeat the patent. By just putting it in the car they force the competition to spend millions on 'reverse engineering' - buying a vehicle and dismantling it, and experimenting with the component until they know how it works inside and out.
