PatCount -- Total number of US Utility patents in the dataset for each fiscal year. USGovtInterest -- Total number of US Utility patents that list a U.S. Gov't interest as derived from bulk data released from the USPTO in XML (and prior SGML/WPK) files.

AnyUSGovtInterest -- Total number of patents that include either USGovtInterest or USGovtOwner, but avoiding double counting (some patents fit both categories).
