A USPTO Suspension Inquiry is a written communication from the United States Patent and Trademark Office (USPTO) inquiring about the status of the event that caused the suspension of your trademark application. For example:
- The examining attorney may have previously suspended action on your application pending the outcome of a trademark opposition you filed against a conflicting trademark in a prior-filed application. In that case, you may periodically receive a Suspension Inquiry asking whether the opposition is still ongoing or whether it has been terminated.
- The examining attorney may have previously suspended action on your application pending the resolution of a trademark cancellation you filed against a conflicting trademark registration. In that case, you may periodically receive a Suspension Inquiry asking whether the cancellation is still ongoing or whether it has been terminated.
- If you filed your trademark application under Section 44(d) (U.S. application based on ownership of a foreign trademark application), and the examining attorney previously suspended action on your application, you’ll periodically receive a Suspension Inquiry asking whether the foreign trademark application has either become a registration or gone abandoned.
