Simon, I'm not sure what the letter of that BCP says, but I think the
spirit  of the requirements is that we should have disclosures regarding
any IPR that may pose concerns for implementation.


As far as I can tell, this is an August 1960 patent.  It's old enough
that no license is required.  I do not see any concerns this poses.

Am I missing something.
