How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Sep 13, 2013, when application PCT/CN2013/083467, the earliest non-provisional in its chain, was filed (this one was filed Nov 2, 2017); a parent in its chain could not be resolved (the next row) | Sep 13, 2033 | 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 | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,735,553, US 9,217,034, US 9,834,606) | resolves to Sep 13, 2033, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 3 maintenance fees paid | lapsed Jun 5, 2026 | High confidence |
| Further caveats on record | The record names parents not resolved: 14736966, 14076214, 14076214 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Jun 5, 2026 | Low confidence |
