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 Sep 18, 2013, when this application, 14/030,866, was filed | Sep 18, 2033 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +6 days, USPTO patent term adjustment record | Sep 24, 2033 | High confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Sep 24, 2033 | High confidence |
Assignments

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

In force means the term is running and no lapse is on record. It is not a finding that the patent is valid.
