Maintenance fee events come from USPTO's own fee records. Its fee lookup asks for the patent number and the application number.
What's changing
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Sep 7, 2032. We will not guess the cap.
