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 Feb 8, 2002, when application 10/072,683, the earliest non-provisional in its chain, was filed (this one was filed Dec 30, 2013); a parent in its chain could not be resolved (the next row) | Feb 8, 2022 | 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 | 1 of 1 maintenance fees paid | term ended | High confidence |
| USPTO status record | Recorded as expired for non-payment on Mar 27, 2023, after the term ended | no change | High confidence |
| Computed term end | The steps above, in order | no later than Feb 8, 2022 | Low confidence |

Note
A terminal disclaimer is on file and its reference is not resolved. No cap is applied and none is guessed
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 8, 2022. We will not guess the cap.
