I believe that
<http://www.ietf.org/ietf/IPR/cisco-ipr-draft-ietf-tcpm-tcpsecure.txt> is a
legitimate filing under the RFC 3668 rules.

 

The sum total of what it says about what the content of the pending patent
application is:

 

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>.

 

I believe that's fair warning, and should be enough to allow the Cisco 

people who know about these patent applications to continue to work in the
IETF.

 

I'd like a world where it was reasonable to say more. But I think saying
that much is possible, and much preferable to saying nothing.

 

In today's world, where it is (according to you) unreasonable to say more,
how should the implementers of this draft IETF specification interpret
Cisco's letter? Should they take comfort that Cisco won't knock on their
door demanding royalties?

 

Or is there no such comfort to be found in IETF specifications and policies?
