Other than one case below, I'm not aware of any IPR.

There is an IPR disclosure in the datatracker on RFC 5961, which is one 
source of changes included in 793bis:

https://datatracker.ietf.org/ipr/421/

In all places in 793bis where the recommendations from 5961 are 
mentioned, 5961 is prominently referenced (making the IPR also easy to 
find) and they are described as optional / "MAY", not required.

Perhaps that disclosure should be updated by Cisco to link to 793bis as 
well?
