Term ends no later than Jan 23, 2034 · Medium confidence
20-year base term ends Feb 6, 2033
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.

|---|---|---|---|
| Base term, 20 years from filing | Clock starts Feb 6, 2013, when application 13/761,084, the earliest non-provisional in its chain, was filed (this one was filed Nov 1, 2013) | Feb 6, 2033 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +351 days, USPTO patent term adjustment record | Jan 23, 2034 | High confidence |

Assignments
Assignment documents as recorded at the USPTO, oldest first, with the reel and frame each was recorded at. A recorded assignment is a filed document, not a statement of current ownership, and the absence of a later one is not evidence that the last one still stands.

What's changing
Jan 2034
Term ends no later than Jan 23, 2034. 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 351 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 Jan 23, 2034. 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.
