"Looks like cisco is trying to bend everyone over a barrel again like they
did for VRRP - except now with TCP, by hijacking the new IETF process to
work on TCP issues. Good way to ensure that everyone can't implement
compatible standards, since free software implementors will not be able to
implement this. When will people learn that RAND == NO FREE SOFTWARE. Of
course, for all we know the applied patents are for Cat Detector vans, so
you have no idea if this is even relevant."
The complete statement from Cisco reads:

Title: Cisco's Statement about IPR Claimed in draft-ietf-tcpm-tcpsecure
Received: April 26, 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.

An additional write up with responses from Theo de Raadt (of OpenBSD fame)
can be found at at KernelTrap here: http://kerneltrap.org/node/view/3085
The IETF draft is here:
http://www.ietf.org/internet-drafts/draft-ietf-tcpm-tcpsecure-00.txt
I love it - collaborate on the IETF draft, then underhandedly patent it.
Funny that Juniper, Wind River, QNX and others also contributed...
Cheers
