Actually not true. There is two IPR statement related to the NAT-T in
the IKEv2 already in the IPR page:

http://www.ietf.org/ietf/IPR/SSH-NAT

and

http://www.ietf.org/ietf/IPR/MICROSOFT-NAT-Traversal.txt


The first one considers all "implementations of an IETF
standards-track specification of an IPSec NAT traversal module"
identical, i.e the text covers both IKEv1 and IKEv2.

The second one only allows using the NAT-T if it is implemented based
on the <draft-ietf-ipsec-nat-t-ike-03.txt> and
<draft-ietf-ipsec-udp-encaps-03.txt> drafts, i.e it propably will not
cover IKEv2.

There is also one more Microsoft IPR claim on the page to the ikev2,
but I do not know any details.

This is about the one patent claim couple of years ago. They never
sent any official IPR statements, so nobody knows if they actually
have anything.
