We shouldn't go too far down this, since this isn't an IPR discussion list,
but the limitations you note are very common in IETF / IRTF IPR
disclosures.  See, e.g.:

* Cisco's disclosure on draft-irtf-icnrg-icn-lte-4g = RFC 9269:
https://datatracker.ietf.org/ipr/5616/
* Google's disclosure on draft-irtf-cfrg-rsa-blind-signatures = RFC 9474:
https://datatracker.ietf.org/ipr/4754/
