Dear all,

in preparation of the WG adoption request we plan for MP-DCCP in the Thursday session, I want to give you a brief update on the existing IPR disclosure https://datatracker.ietf.org/ipr/3639/.

This one was submitted along with our very first MP-DCCP draft in 2019. At this time the related invention was still in the review phase at the European patent office, which required finally adjustments of the patent claims. The new claims does not cover anymore the specifications in the MP-DCCP draft.

For that reason, we updated the IPR disclosure adding the following note:

"During the review process by the European Patent Office and after some necessary adjustments of the claims, this patent lost according to the understanding of the applicant its relation to the MP-DCCP draft (https://datatracker.ietf.org/doc/draft-amend-tsvwg-multipath-dccp/). For the avoidance of doubt, this addition to the original declaration does not constitute a revocation of the original declaration in case there may be still an relation to the MP-DCCP draft in contrast to the understanding of the applicant."

The update was done on Monday, but seems to be stuck in the IETF secretariat, which is probably busy because of the ongoing IETF111. So it is not published yet, but we will expect it soon on the datatracker.

We hope that this updated declaration will prevent any IPR related issues for a potential WG adoption. Please provide your feedback here, if any, ahead of tomorrow's TSVWG meeting.
