Term ends no later than Nov 22, 2029 · Medium confidence
20-year base term ends Aug 11, 2029
In force on USPTO's status record and by its fee record. A terminal disclaimer on file may shorten this term, possibly to a date already past; its reference document is unresolved, so the date above is an upper bound and no earlier date is guessed.

Term ends no later than Nov 22, 2029. Maintenance fees still fall due before then

Open question
A terminal disclaimer is on file (filed) and its reference document is not resolved. A disclaimer would cap the term earlier than Nov 22, 2029. We will not guess the cap.

How we rank
Every date shows its work: the base term, any term adjustment or extension, any disclaimer cap, and the maintenance fee record, each with a confidence tier. How this record was built
This computed term ends no later than the date shown; an unresolved terminal disclaimer may end it earlier. Related patents and pending applications may cover overlapping subject matter.
In force means the term is running and no lapse is on record. It is not a finding that the patent is valid.
