Supplementary notes
Note: World totals are WIPO estimates using data covering 83 patent offices. These totals include applications filed directly with national and regional offices and applications entering offices through the Patent Cooperation Treaty national phase (where applicable). China’s pre-2017 data are not comparable due a change in methodology. Due to this break in the data series and to the large number of filings in China, it is not possible to report accurately the 2017 growth rate at world level (see the data description section in Additional information for details).
