| Patent term extension | None on file | no change | High confidence |
| Fee events | 1 of 3 maintenance fees paid | In force | High confidence |
| Further caveats on record | The record names parents not resolved: PCTUS2012069516, PCTUS2012069516 | Low confidence overall | Low confidence |

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.
