Non-spyderco compression locks?

I think I'm right in saying that Spyderco holds the patent to the compression lock. Has anyone else used it, like how some makers get permission from Benchmade to use the axis lock?
 
One maker that comes to mind is Jesse Jarosz.

Some of Benchmade's gentlemen's folders use their "nak-lok" mechanism, which is very similar. It operates on the same principle (liner lock where you don't put your hand in the way of the blade), but instead of pushing directly on the liner as you do with Spyderco, you push on a button attached to the liner. The elegant looks of a plunge lock with the strength and lockup of a liner lock. Pretty nifty.
 
Nak lock is nothing like a compression lock. I suggest you watch Jesse Jarosz' vid on it which he explains it.

A compression lock is not a liner lock. The nak lock is a button actuated liner lock hence not close.

I could argue that the axis lock is closer to the compression lock in how it holds the knife open.
 
Hm, it seems like the Puzzle Lock is a lot like a Compression Lock without the stop pin, which seems would be getting rid of the largest strength feature of the Compression Lock. I didn't read the patent in too much detail, but I'm having trouble seeing how it could be equal to, no less superior to, the Compression Lock.

The Nak Lok is almost the opposite of the Compression Lock. Other than it's superficially similar UI, the lock mechanism is essentially a Liner-Back Lock (ie. a metal hook holding the blade open via tension).

I agree with Scurvy, despite very different UI's the Axis Lock is a pretty close comparison to the Compression Lock, as far as how it actually locks the blade (ie. a compressive system using the blade tang, liner(s), and a steel pin).
