How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Jan 22, 2014, when application PCT/JP2014/051296, the earliest non-provisional in its chain, was filed (this one was filed Aug 10, 2023); a parent in its chain could not be resolved (the next row) | Jan 22, 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 | None on file | no change | High confidence |
| Terminal disclaimer cap | Disclaimer on file (approved), reference document not resolved | no cap applied, and none guessed | Medium confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 0 of 2 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | no later than Jan 22, 2034 | Low confidence |
