Continuity chain	Every parent in the chain resolved	no change	High confidence
Patent term adjustment	+152 days, USPTO patent term adjustment record	Sep 30, 2033	High confidence
Terminal disclaimer cap	Disclaimer resolved from the filed document (refs US 9,154,303)	capped to May 15, 2033	High confidence
Patent term extension	None on file	no change	High confidence
Fee events	The fee record shows no payment for this window, and USPTO's status still reads "Patented Case"	lapsed Jul 17, 2026	Medium confidence
Further caveats on record	The record rates this date lower than the steps above account for	Low confidence overall	Low confidence
Computed term end	The steps above, in order	Jul 17, 2026	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.
