| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts May 30, 2007, when the earliest non-provisional application in its chain was filed (this one was filed Apr 15, 2020); a parent in its chain could not be resolved (the next row) | May 30, 2027 | 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 | +64 days, USPTO patent term adjustment record | Aug 2, 2027 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 10,662,421, US 8,679,741, US 9,453,257) | capped to Jun 19, 2027 | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | No maintenance fee can end the term early | In force | High confidence |
| Further caveats on record | The record names parents not resolved: 15240692, 12301985, 12301985 | Low confidence overall | Low confidence |
| Computed term end | The steps above, in order | Jun 19, 2027 | Low confidence |

USPTO account required: This application in Patent Center · USPTO's maintenance fee lookup
Maintenance fee events come from USPTO's own fee records. Its fee lookup asks for the patent number and the application number.
Not on this page: the patent's family, its recorded assignments and its citation count. USPTO's assignment records, linked above, list every recorded assignment.
Every date shows its work: the base term, any term adjustment or extension, any disclaimer cap, and the maintenance fee record, each with a confidence tier. How this record was built
Computed patent terms end on the dates shown. Related patents and pending applications may cover overlapping subject matter.
In force means the term is running and no lapse is on record. It is not a finding that the patent is valid.
