Phil, we've got some interesting info from rec.knives here. Somebody asked about the patent status or similar on the Sebenza Integral lock and it's legality on the BM Pinnacle and other "Sebenza clones".
Take a look:

I'm still awaiting my Sebenza, but having handled tons of them, I can say that I don't think the Pinnacle is a copy.
The main similarity is the locking mechanism. That mechanism is not patented by Reeves, and in fact other makers have used this kind of mechanism. The reason people seem to be "raising the alarm" about the Pinnacle and not those other makers/manufacturers is that Benchmade has done it particularly well-done and affordably.
Benchmade approached some parts of the locking mechanism differently -- look at Reeves two vertical slots versus Benchmade's long horizontal one. Anyway, that's the main similarity, the lock. Is every liner lock a "copy" of the really old liner locks?
The handles are one-piece titanium, but that's an artifact dictated by the lock. Every integral-style lock I know of is titanium slabs, and so superficially looks like the SEbenza -- e.g., the CRK&T S-2, Elishewitz's integral locks, the Pinnacle, Darrel Ralph's new Apogee integral lock etc. So the titanium handles are given. But Benchmade's handle is different than the Sebenza's, and much more ergonomic and easy to hold onto from what I can tell.
The blades are completely different. The Pinnacle uses a Walter Brend blade, sabre-ground and recurved. The Sebenza's blade is a high-hollow grind, no recurve.
You could just as implausibly say the Pinnacle is a Brend copy as a Sebenza copy, IMO.

Jim again. The implication is that the Integral lock is free for use. Considering that Chris Reeve has sworn never to make a folder with a blade over 3.5" I don't think anyone will look down on Camillus for using this lock on a 5.49" megafolder.
Does anyone else agree that with a training manual that says "grab it TIGHT to reinforce the lock in a fight" I really think it'd work.
It's by no means the sole option of course...
