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 Feb 25, 2014, when application 14/188,944, the earliest non-provisional in its chain, was filed (this one was filed Feb 29, 2016); a parent in its chain could not be resolved (the next row) | Feb 25, 2034 | 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 | +198 days, USPTO patent term adjustment record | Sep 11, 2034 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 9,286,640) | capped to Feb 25, 2034 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 3 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 14188944 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Feb 25, 2034 | Low 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
Computed patent terms end on the dates shown. 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.
