Term ends no later than Nov 22, 2026 · Low confidence

Computed 20-year base term

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

Term ends no later than Nov 22, 2026. No further fees 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

Open question

A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Nov 22, 2026. We will not guess the cap.

That is below the median of utility patents granted in 2015 in our data, the only group it is compared against. 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.
