Summary

Description
English: Chart showing clean energy patent filings by various countries, annually
  • Data source: Bearak, Max; Rojanasakul, Mira. Bearak, Max; Rojanasakul, Mira (14 August 2025). "How China Went From Clean Energy Copycat to Global Innovator". The New York Times. Archived from the original on 15 August 2025.

1. Source states: "Over two decades China has leapt ahead of other countries, churning out innovative designs for the energy mix of the future: solar and wind power, batteries and electric cars."
2. Source states: "Source: European Patent Office, Espacenet. Note: Clean energy categories include batteries, biofuels, hydrogen, photovoltaics, and supercapacitors." Based on quote in the preceding paragraph #1, this chart does not exclude other categories like solar and wind.
3. Source states: "Patent data was provided by the European Patent Office, with each clean energy technology category based on either the Y02 tagging scheme or custom analysis done in part with the International Energy Agency. The count of patents is based on "international patent families," which must be filed in at least two countries and excludes duplicative filings that cover the same invention."
4. Source states: "The European Patent Office data considers any application that has been filed in two or more countries to be high quality, based on the assumption that companies went through the trouble and expense of applying for a patent in more than one market with the intention of protecting their invention across borders." This distinguishes the "high quality" patents that are the subject of this chart, from "low quality" patents.
  • Technical note: SVG code for the axes and gridlines was automatically generated by the "Line charts" spreadsheet linked at User:RCraig09/Excel to XML for SVG. Data lines were "traced" in Inkscape, and manually simplified in a text editor. Additions and adjustments were made in a text editor.
 This W3C-unspecified vector image was created with Inkscape .
