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 May 20, 1999, when the earliest non-provisional application in its chain was filed (this one was filed Nov 15, 2006); a parent in its chain could not be resolved (the next row)	May 20, 2019	High confidence
Continuity chain	A parent in the chain could not be resolved	dated from this application's own claim	Medium confidence

Maintenance fee events come from USPTO's own fee records. Its fee lookup asks for the patent number and the application number.

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
