Dear all,

I'd like to follow up on the previous WGLC announcement regarding
draft-ietf-cose-merkle-tree-proofs. As a reminder, the previous email
requested your input on whether the disclosed IPR impacts your support for
publication of this document.

To facilitate the next steps in this process, I kindly request your *response
by February 11th (2 weeks from now)*. Feel free to only reply to the WG
chairs. Please indicate whether:

* (a) You require additional time to form an opinion.
* (b) You have an opinion (please share it).
* (c) You do not have an opinion.
* (d) You have an alternative proposal for a path forward.

Your timely response will be greatly appreciated and will assist us in
moving forward.

Thank you for your attention to this matter.
