The text of the original IPR declaration:

Extracted from a message sent to the IESG on November 22, 1996 from

Dan Scheinman
Chief Corporate Counsel
Cisco Systems, Inc.

IGRP is a proprietary protocol of Cisco, and Cisco believes at this
time, that the proposed submission violates Cisco's rights in the
protocol and in the trademark.  Therefore, Cisco believes the internet
draft should not be published.  Cisco's practice has been and continues
to be that it will openly and fairly license its technology through its
IOS software.  However, Cisco cannot endorse this action.  If you have
any questions, please contact Stu Phillips (, Vice
President, Central Engineering.
