Title: Cisco's Statement about IPR Claimed in draft-ietf-tcpm-tcpsecure
Updated: May 17, 2004
From: Robert Barr 

Cisco is the owner of one or more pending patent applications relating to
the subject matter of "Transmission Control Protocol security
considerations" . 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 be
able to obtain a license from Cisco 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, provided,
however that Cisco retains the right to assert its patents (including the
right to claim past royalties) against any party that asserts a patent it
owns or controls (either directly or indirectly) against Cisco or any of
Cisco's affiliates or successors in title for an implementation of any IETF
standard; and Cisco retains the right to assert its patents against any
product or portion thereof that is not necessary for compliance with the
standard.

Royalty-bearing licenses will be available to anyone who prefers that
option.
