The methodology used was based on four primary criteria:
- Success: The ration of patent applications to patent grants over the course of the past three years
- Global reach: The percentage of the patent portfolio recognised and protected by the major patent authorities in the US, Chinam Europe and Japan
- Influence: The long-term impact of innovations, as measured by how often the patent is cited within the industry
- Volume: The number of new techniques or inventions created – excluding patents that refine existing innovations
The U.S. comes first as the most innovative country, with France and Sweden the most innovative in Europe.
