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 Apr 5, 2024, when application 18/628,636, the earliest non-provisional in its chain, was filed (this one was filed Dec 16, 2024); a parent in its chain could not be resolved (the next row) | Apr 5, 2044 | 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 12,171,084, US 12,733,132) | capped to Mar 15, 2025 | 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 |
| Further caveats on record | The record names parents not resolved: 18780850, 18628636 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Mar 15, 2025 | Low confidence |
