Unresolved
Terminal disclaimer
On file, reference document not resolved, so the date above is an upper bound. We do not guess the cap.

This patent's term runs 35 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. 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 Dec 29, 2000, when application 09/751,647, the earliest non-provisional in its chain, was filed (this one was filed May 16, 2016); a parent in its chain could not be resolved (the next row) | Dec 29, 2020 | 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 | +35 days, USPTO patent term adjustment record | Feb 2, 2021 | 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 | No maintenance fee can end the term early | term ended | High confidence |
| USPTO status record | Recorded as expired for non-payment on Jul 3, 2023, after the term ended | no change | High confidence |
| Computed term end | The steps above, in order | no later than Feb 2, 2021 | 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 35 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 Feb 2, 2021. We will not guess the cap.
