Countries by priority year
The countries filed in according to the year of the priority document were analyzed. For this analysis, PCT patent applications (WO) were removed, and all European patent filings were merged. As seen in the chart, with few exceptions most of the earliest patent filings are in the United States, Europe, Australia, Japan, and Canada. In later years, more patent applications show up in other than high-income countries.
