This is to inform you that I am aware of potential IPR on the following:

	draft-ietf-sip-update-01
	draft-ietf-sip-manyfolks-resource-05

These are a direct consequence of the fact that both drafts are derived
from draft-rosenberg-sip-unify-00, for which I had already disclosed
IPR. These are, of course, covered by our statement of terms:

"dynamicsoft may seek patent protection on technology described in
documents which dynamicsoft submits for use in IETF standards
discussions. In relation to any IETF standard incorporating any such
technology, dynamicsoft will grant a royalty free non-exclusive license
to Qualified Parties to utilize such technology if necessary for
practice of IETF standards implemented as a result of dynamicsoft's
submission. As used herein, Qualified Parties means a party who has
not, does not and will not assert, in litigation or otherwise, including
in licensing discussions, any patent or other intellectual property
right against dynamicsoft. Any such license to a Qualified Party shall
terminate at once if such party asserts a patent or other intellectual
property right against dynamicsoft. dynamicsoft will grant
non-exclusive licenses to Non-Qualified Parties on reasonable,
reciprocal non-discriminatory terms and conditions."
