Measuring patent quality in cross-country comparison

Author

Listed:
  • Boeing, Philipp
  • Mueller, Elisabeth

Abstract

Our novel quality index is based on citations from international search reports and provides internationally comparable, quality-adjusted figures for applications made under the Patent Cooperation Treaty (PCT). We show that China’s recent patent expansion has taken place to the detriment of patent quality. Weighting national PCT counts with our index reveals a widening gap between the technological capacities of China and the leading USA.
