http://www.ripe.net/ripe/wg/ncc-services/r59-minutes.html has an interesting quote - probably the one useful nugget in that discussion.
--- and i quote ---
John Curran (ARIN) explained how this is done in the ARIN region. He said that ARIN does verification, but when a fraud is uncovered, ARIN does act to revoke resources. This is not related directly to the criminal activities, but due to a violation of the policy.
Uwe agreed that it is not the RIPE NCC's job to determine what is legal or not, but pointed out that allowing somebody that obtained resources to use these resources for illegal purposes leaves him outside the law. He said that he will present propositions to the mailing list to reformulate the text in RIPE Document ripe-452 to revoke resources if an organisation if found not to actually exist.

So - if you wouldn't want to ask a microsoft lawyer, please feel free to ask ARIN what they do to verify paperwork, and to reclaim fraudulently registered address space.
The various RIRs all cooperate and discuss these matters. The ARIN region is very different to that of RIPE NCC, but in short, yes, these discussions have taken place and will continue to do so. Brian.
