Distribution of the number of patents following different criteria. The information was extracted from the data of the patent search. a The figure shows the countries where the selected patents were granted. In case of multiple publications, the country of earliest granting is mentioned. The pie size for each country corresponds with the total number of patents first applied or granted there. Other = Canada, Italy, Japan with each one patent. b The figure reveals the distribution of patent ownership.
