I need plankton to confirm this, but to me this means the patent in it's revised form is issued and published in the Gazette...yesterday was Tues...but I just looked and don't see the official entry? That may not hit the paper trail till next Tues. They do everything in mini steps.
NIRC is notice of intent to re-issue the certificate.
Issue date means we are complete.
9/20 to 10/16 = 26 days with 47 being the avg.
I'd guess we see a PR pronto.
