Term ends no later than Apr 11, 2033 · Medium confidence
20-year base term ends Dec 14, 2031
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.

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.

USPTO account required: This application in Patent Center · USPTO's maintenance fee lookup
Maintenance fee events come from USPTO's own fee records. Its fee lookup asks for the patent number and the application number.
What's changing
Apr 2033
Term ends no later than Apr 11, 2033. 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 484 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 Apr 11, 2033. We will not guess the cap.

later US patents cite this one
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.
