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.
I did not notice the date.
More worrisome, I cannot read the reference. The link goes to a page
which says 'Full text is not available for this patent. Click on
"Images" button above to view full patent' and when I click on "Images"
I get nothing because the page appears to require some non-standard
plugin that I don't have installed.
/Simon
