This patent's term runs 167 days past its 20-year base term on prosecution delay. A terminal disclaimer is on file with no resolved reference, so no cap is applied and none is guessed. All three maintenance fees were paid, so no fee lapse ended it. Confidence: Low. 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 Aug 11, 1999, when application 09/374,142, the earliest non-provisional in its chain, was filed (this one was filed Sep 23, 2005); a parent in its chain could not be resolved (the next row) | Aug 11, 2019 | 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 | +167 days, USPTO patent term adjustment record | Jan 25, 2020 | 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 | 3 of 3 maintenance fees paid | term ended | High confidence |
| Computed term end | The steps above, in order | no later than Jan 25, 2020 | Low confidence |

What's changing
Note
A terminal disclaimer is on file and its reference is not resolved. No cap is applied and none is guessed
Note
The 167 days of patent term adjustment (USPTO delay) are read from the USPTO record, not recalculated by us
Open question
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Jan 25, 2020. We will not guess the cap.
