Maintenance fees paid
Three maintenance fees fall due, at 3.5, 7.5 and 11.5 years from grant. This counts the ones the record shows paid.
This patent's term runs 593 days past its 20-year base term on prosecution delay. A terminal disclaimer resolved from the filed document caps it earlier. All three maintenance fees were paid, so no fee lapse ended it. Confidence: High. from the record
