[core] IPR poll for draft-ietf-core-coap-pubsub

I'll take the liberty to reuse, thanks. I might even have a license from 
IETF Trust to do so :)  )
Dear all,

I am sending this message as an IPR poll for the document 
draft-ietf-core-coap-pubsub of which I am the Shepherd.

https://datatracker.ietf.org/doc/html/draft-ietf-core-coap-pubsub

As you all know, there are certain requirements about declaring patent 
claims (called "IPR" in IETF lingo) that you are personally aware of and 
that apply to a contribution (another IETF term) you make to the IETF.

These requirements do not change with IESG submission of a document, but 
that milestone provides a convenient check point, particularly for all 
authors and contributors listed, to indicate that such "IPR 
declarations" have been made as required, or possibly an assertion that 
you are not personally aware of patent claims that would "read" on that 
document. Note that this is about what you personally know, not about 
needing to consult your employer's corporate lawyers to state a legal 
opinion.

So: If you are **personally aware of any patent claims** that might 
apply to systems that implement this draft, please review BCP 78 [1] and 
BCP 79 [2] and make any appropriate IPR declaration now. If you are not 
sure whether you need to make a declaration or not, please talk to the 
chairs ([e-mail])

**If you are an author or listed contributor** and do not know about a 
pertinent patent claim (granted or in processing), please simply do a 
wide reply to this message and state:

"I am not personally aware of any patent claims that would read on this 
specification."

(Creating the Shepherd write-up is blocking on the authors' responses.)

Best regards,
Esko Dijk
