Submitter:  Dan Lang <dlang@cisco.com>



Cisco is the owner of US Patent Nos. 7,190,678, 7,203,175, 7,209,978,
7,366,111, 7,428,221, and 7,649,852, US Published Patent
Applications 20060291404, 20070091811, 20070153764, and 20080219237,
and US Patent Application Serial No. 11/984,049 relating to the
subject matter of "RPL: IPv6 Routing Protocol for Low power and Lossy
Networks" <draft-ietf-roll-rpl-06>.

If technology in this document is included in a standard adopted by
IETF and any claims of any Cisco patents are necessary for practicing
the standard, any party will have the right to use any such patent
claims under reasonable, non-discriminatory terms, with reciprocity,
to implement and fully comply with the standard. The reasonable non-
discriminatory terms are: If this standard is adopted, Cisco will not
assert any patents owned or controlled by Cisco against any party for
making, using, selling, importing or offering for sale a product that
implements the standard. Cisco retains the right to assert its patents
against any product or portion thereof that is not necessary for
compliance with the standard.

To maintain reciprocity, notwithstanding anything to the contrary,
Cisco retains the right to assert its patents (including the right to
claim past royalties) against any party that asserts a claim of a
patent it owns or controls (either directly or indirectly), where such
claim is necessary for practicing the standard, against Cisco or any
of Cisco's affiliates or successors in title or against any products
of Cisco or any products of any of Cisco's affiliates either alone or
in combination with other products, where such assertion by such party
is directed against implementation of the standard.
