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 Mar 20, 2002, when application 10/102,413, the earliest non-provisional in its chain, was filed (this one was filed Jul 25, 2016); a parent in its chain could not be resolved (the next row) | Mar 20, 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 | +108 days, USPTO patent term adjustment record | Jul 6, 2022 | High confidence |
| Terminal disclaimer cap | None on record | no cap applied | High 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 May 29, 2023, after the term ended | no change | High confidence |
| Computed term end | The steps above, in order | Jul 6, 2022 | Medium confidence |
