Re: Cisco's Statement about IPR Claimed in draft-ietf-tcpm-tcpsecure

What's very amusing is reading section 5 of the draft, wherein the author
distributes credit to a number of parties. If Cisco were to file a patent
at this point and not include those parties (including other companies),
the patent validity would be at risk by reason of excluding a contributor.
If Cisco does include all of those other companies in the patent, then all of
them must also present the IETF with relevant IPR statements.

Frankly, this is yet another PR blunder by Cisco. If they had simply said
nothing or formally put their contribution into the public domain, they wouldn't
look so egregiously greedy.

Title: Cisco's Statement about IPR Claimed in draft-ietf-tcpm-tcpsecure
Received: April 26, 2004
From: Robert Barr <[email protected]>

Cisco is the owner of one or more pending patent applications relating to
the subject matter of "Transmission Control Protocol security
considerations" <draft-ietf-tcpm-tcpsecure-00.txt>. 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.
