Term ends no later than Jun 13, 2036 · Medium confidence
20-year base term ends Dec 16, 2035
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.

What's changing
Jun 2036
Term ends no later than Jun 13, 2036. Maintenance fees still fall due before then
Note
A terminal disclaimer is on file and its reference is not resolved. No cap is applied and none is guessed
Note
The 180 days of patent term adjustment (USPTO delay) are read from the USPTO record, not recalculated by us
Open question
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Jun 13, 2036. 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.
