Patent quality , national technological capacity , cross-country comparison
Abstract:
China recently surpassed the USA as the greatest global source of patent applications. However, without internationally comparable measures of patent quality it remains questionable whether China’s patent
expansion constitutes the rise of a new technological superpower. 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 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.
