I haven't read the patent in detail, but from perusing the various posts here, if in fact the details are accurate, I've come across this system, in one form or another on several sites, for quite some time now.

I too share the reservations of some re: enforceability.

As a case in point, I've wondered for quite some time now on any patents that vivisimo might have. In addition, if they do, how would they ever decide on how to enforce their clustering method when considering the great number of websites that use clustering, as well as the fact that similar clustering methods as theirs have existed for many years prior to vivisimo.

Just food for thought, and I used v as an example only. I have no idea if they have a clustering patent at all.
