STOP PRESS: The IPKat hears from reports here and here that the USPTO has been enjoined (for English speakers read "prevented") from bringing into force the proposed new rules relating to claims and continuations. These were due to come into force tomorrow (1 November), but have now been put off for at least a couple of months while a US court reaches a final decision.
US patent applicants can breathe a (temporary) sigh of relief, and allow themselves a Happy Halloween.
(right: the IPKat in disguise has a little celebration).
For more information on this and other US patent matters, the IPKat highly recommends Dennis Crouch's Patently-O blog.
