Googling for it without forcing a phrase match returns some limited results. Here's a patent for a "Spatial Sieve Tree", which is apparently invented by the parent, jandrewrogers: http://www.google.st/patents/US7734714

In that case I am glad it is not covered in literature. Patenting algorithms is bad.

Yep, that was the first practical spatial sieve (previous variants had pathological spatial skew sensitivity). Most people that use them use more sophisticated variants. Even with that version, which is simple, many implementors do not understand the technical subtleties well enough to produce a non-broken implementation.
