The other problem with increased complexity is that the more intricate your mechanism is, the more prone to failure due to wear or contamination it becomes. A security measure is only as good as it can remain usable. As a locksmith for working in the industry for 25 years, I've seen a lot of high security designs come and go, and the stuff that sticks is the stuff that's simple and reliable. The fundamental fact of locks and security is that people just don't pick locks much. The vast overwhelming majority of unauthorized accesses are via an acquired key or via bypass attacks on other aspects of the locking hardware than the keyed cylinder.

To put it bluntly, all these fancy pick-proof designs people are coming up with have zero real world utility and are just toys for locksport enthusiasts to play with.

EDIT: and really, I'd say all the patent discussion is moot. A patent is only useful if there's a market for your product. This product has design shortcomings that render it a non-starter for most applications, i.e. no master keying capacity, which makes it useless in any institutional setting, and a design necessity of using critical precision parts that won't handle outdoor exposure well, and a physical size that makes it incompatible with even the largest north american cylinder format. This is a product without a profitable customer base.
