about USPTO patent issue dates: I tried a search at uspto.gov, through the advanced search you can use issue date as your search criteria.  I tried every day of the week for several weeks, for example - input several Mondays:

isd/7/1/2013
or isd/6/24/2013
or isd/6/17/2013
or isd/6/10/2013
or isd/6/3/2013

zero results are returned, input several Tuesdays:

isd/7/2/2013
or isd/6/25/2013
or isd/6/18/2013
or isd/6/11/2013
or isd/6/4/2013

and 28,061 results are returned, Wednesday, Thursday, Friday all return zero.

Are we waiting for a tuesday afternoon PR???
