I've noticed that the '336 was shuffled around from record room to Franconia. Then status of it's location has been "Electronic" since about May 8 after going to "RTIS scanning" where it remains to date.
Yesterday, '148 was sent from record room back to "File repository Holding Area" and then to "Franconia"...all of which is a repeat pattern starting from Mar. 16.
Perhaps once it gets sent to "RTIS scanning" and then "Electronic" (current '336 status) they are ready for the next step in the process (Patenability Review Conference)?
