Some award records list only a year, or report no amount. The figures above still reflect them where the source gives an amount.

What it has protected

No granted patents are on record.

USPTO usually publishes applications 18 months after filing, so recent applications may not be visible yet. Patents assigned under a different entity name won’t match.
