This patent's term runs 190 days past its 20-year base term on prosecution delay. A terminal disclaimer is resolved from the filed document, and it ends no earlier than this term, so it shortens nothing. All three maintenance fees were paid, so no fee lapse ended it. Confidence: High. from the record
