Re: [EXTERNAL] [PNG] Meeting minutes - Nov 14th, 2022

The First Public Working Draft of a specification is a Patent Review 
Draft [1] and triggers an exclusion opportunity [2], which lasts for 5 
months. The FPWD of PNG 3rd edition was published on 2022-10-25 and so 
the exclusion opportunity lasts until 2023-03-24 [3].

Material added after that date is not covered until the next exclusion 
opportunity, which is triggered by publication of a Candidate 
Recommendation Snapshot [4] (which is also a Patent Review Draft).
