Sources and methods
Compiled from USPTO application file histories, grants and recorded assignments, with the company's own names reviewed by hand. How this record was built
Portfolio grouped automatically from ownership conveyances to the names matched to this company, usually every name that begins with its own, so it counts patents an affiliate holds; each list row names the holder of record. Security interests are excluded and ambiguous records are not reviewed by hand.
Computed patent terms end on the dates shown. Related patents and pending applications may cover overlapping subject matter.
2 terminal disclaimers are on file with no resolved reference. No cap is applied and none is guessed
9 computed term dates come from a chain with an unresolved parent. A continuity parent has not yet been fetched from USPTO's records. The term is dated from this application's own claim; no earlier date is assumed until the parent is resolved.
