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?

Tony
