Its term would have run to Jul 6, 2027: its 20-year base term, with no adjustment for prosecution delay. A terminal disclaimer is resolved from the filed document, and it ends no earlier than this term, so it shortens nothing. Confidence: Medium. from the record
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 Jul 6, 2007, when application PCT/IB2007/001866, the earliest non-provisional in its chain, was filed (this one was filed Sep 18, 2015); a parent in its chain could not be resolved (the next row) | Jul 6, 2027 | 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 9,200,355) | resolves to Jul 6, 2027, no earlier than this term, so no change | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 2 maintenance fees paid | lapsed Jun 26, 2026 | High confidence |
| Computed term end | The steps above, in order | Jun 26, 2026 | Medium confidence |
