I don't have a "legal department to challenge the patent", but in case it helps:

  http://www.ninebynine.org/SWAD-E/Scenario-HomeNetwork/HomeNetworkConfig.html

This was work I did around 2002-03, and includes use of RDF technologies to set access controls on a Cisco IOS router, which appears to correspond to the first primary claim of the patent:

[[
1. An enforcement system for enforcing policies with regard to service requests comprising a processor-readable, non-transient medium storing code representing instructions that when executed at a processor cause the processor to implement: a plurality of enforcer agents adapted to enforce policies; at least one explorer agent adapted to evaluate policy enforcement capabilities available to the enforcement system; and a policy decision point adapted to identify the policies that need to be enforced for a service request and to pass this information to at least one enforcer agent to enforce the identified policies.
]]

I recall there was also an Internet draft published about this time that talked about using RDF in a network management control layer: see http://tools.ietf.org/html/draft-atarashi-netconfmodel-architecture-00.

Dear all:

Yesterday, Hewlett Packard has been granted a patent on "Policy Enforcement":

As far as I can see, it heavily constrains the commercial exploitation of 
research done in the Semantic Web / Semantic Web Services community from 
2001-2009.

So if you worked on policies in the context of Semantic Web Services or 
Semantic Business Process Management before November 2009, it may be worthwhile 
to check whether the patent claims inventions that you can prove to have been 
prior art at that time.

This may be particularly relevant for the organizers and contributors to the 
various policy workshops co-located with ISWC/ESWC conferences.

I am not familiar with the legal process, but if you feel this patent claims 
what was already publicly known / discussed at conferences back then, please 
ask your employer or legal department to challenge the patent. It may otherwise 
put the usage of SWS in business applications at risk.

Best wishes

Martin
