After scanning the claims, though, most of this is about access-rights
enforcement; which is something that rules *could* be used for but it's
not their sole or main purpose.  What it seems a whole lot closer to
is Veil or SEPostgres.  I think those projects have reason to be very
afraid.

In fact, I suspect that the originally submitted version of SEPostgres
does infringe the patent, and that code is not old enough to be prior
art.  The part of the patch that looks like this patent to me is the
part that enforces row-level access checks by adding constraints to a
querytree's WHERE clause.

I had already suggested to KaiGai-san that he get rid of that in favor
of low-level checks in the executor, but the need to avoid an M$ patent
makes it even more important ...
    

Yes, I've changed the originally submitted version of SE-PostgreSQL.
The latest version of its implementation does not have any feature
to modify given queries. All of low-level checks are moved to hard
wired hooks in ExecScan().

BTW, I may have to backport the feature for v8.4 into v8.3/v8.2
based SE-PostgreSQL... :(

Subject:  objecting to a patent

Is there a process that allows someone to object to a patent given to a 
company where there is  prior art done by another entity that is a Non 
for Profit  that the patent office was not aware of.

thank you
