An answer was due in this proceeding a long time ago, and we have not received a copy of an answer from the defendant. What happens next?

Check  TTABVUE  to see whether an answer has been entered in the file. If not, the TTAB sets the call-back date for entry of a notice of default about 10 days after the answer was due. You will receive a copy of the notice of default and/or email notification when a notice of default issues. If an answer has been filed on paper it will be scanned into  TTABVUE  and you should be able to view it there.
