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.
