[Wearing no hat, except my Cisco affiliation] Tony,
Your email prompted me to check in the data tracker DB and with Cisco legal dept about the timeline for this IPR disclosure about RFC 8402. I am afraid that the chronology leaves out two previous clusters of disclosures by Cisco, in 2013 and 2014. Those are: - in 2013 https://datatracker.ietf.org/ipr/2275/ - in 2014 https://datatracker.ietf.org/ipr/2457/ The recent disclosure was triggered by some continuation applications; it is just an update of the previous ones. I hope it helps to clarify the situation, -éric -----Original Message----- From: spring <spring-boun...@ietf.org> on behalf of Tony Li <tony...@tony.li> Date: Tuesday, 19 April 2022 at 00:58 To: IETF Secretariat <ietf-...@ietf.org> Cc: "spring@ietf.org" <spring@ietf.org>, "draft-ietf-spring-segment-rout...@ietf.org" <draft-ietf-spring-segment-rout...@ietf.org>, "ipr-annou...@ietf.org" <ipr-annou...@ietf.org> Subject: Re: [spring] IPR Disclosure Cisco Systems, Inc.'s Statement about IPR related to RFC 8402 Let me see if I understand the timeline here: 2013, June 28, Draft submission of draft-filsfils-rtgwg-segment-routing-00 2018, July, Published as RFC 8402 2020, July 30, US patent filed for Enforcing strict shortest path forwarding using strict segment identifiers 2022, Apr. 18, IPR declaration filed Do I have that right?
