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 Nov 27, 2006, when application PCT/JP2006/324128, the earliest non-provisional in its chain, was filed (this one was filed Aug 27, 2013); a parent in its chain could not be resolved (the next row) | Nov 27, 2026 | 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 | +13 days, USPTO patent term adjustment record | Dec 10, 2026 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 8,043,265) | resolves to Dec 10, 2026, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 2 of 2 maintenance fees paid | In force | High confidence |
| Computed term end | The steps above, in order | Dec 10, 2026 | Medium confidence |
