Term ends no later than Mar 20, 2042 · Low confidence
20-year base term ends Jun 4, 2039
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.

This patent's term runs 1020 days past its 20-year base term on prosecution delay. A terminal disclaimer is on file with no resolved reference, so no cap is applied and none is guessed. 0 of 3 maintenance fees are paid so far. Confidence: Low. from the record
How we calculated this date
One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Jun 4, 2019, when application 16/431,167, the earliest non-provisional in its chain, was filed (this one was filed Apr 20, 2020); a parent in its chain could not be resolved (the next row) | Jun 4, 2039 | High confidence |
| Continuity chain | A parent in the chain could not be resolved | dated from this application's own claim | Medium confidence |
| Patent term adjustment | +1020 days, USPTO patent term adjustment record | Mar 20, 2042 | High confidence |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 0 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | no later than Mar 20, 2042 | Low confidence |

Term ends no later than Mar 20, 2042. Maintenance fees still fall due before then

A terminal disclaimer is on file and its reference is not resolved. No cap is applied and none is guessed

The 1020 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 Mar 20, 2042. We will not guess the cap.

Fewer than half of the utility patents granted in 2024 in our data have been cited yet, so we show the count and do not rank on it.
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.
