(Update: USPTO leadership has, indeed, taken corrective action (blog article).)
It crosses my mind that this kind of thing with the EBC telling people that Patent Center is not ready (see blog article) will very likely lead to a corrective action by USPTO leadership. No, I do not mean that USPTO leadership will postpone the shutdown of PAIR and EFS-Web (now planned for November 8) until Patent Center is “ready”. Nor do I mean that USPTO leadership will actually do the hard work of making Patent Center “ready” between now and November 8. I mean that a memo will get circulated to the representatives at the EBC, telling them that between now and November 8, no user is to be told that the workaround for a Patent Center bug is to “use PAIR instead” or “use EFS-Web instead”.
