Considering various factors including number of patent applications, the IP & Science business of Thomson Reuters puts Ford, Honda, Nissan, and Toyota on its 2013 Top 100 Global Innovators list. Joining those OEMs on the list are several automotive suppliers including Delphi, Jatco, NGK Spark Plug, and Valeo. Honda and Toyota have earned their way onto the list in each of the three years since intelligence-information provider Thomson Reuters began compiling it. Michelin and Goodyear Tire & Rubber also made the list as "non-automotive" suppliers.To determine the top 100 companies, Thomson Reuters uses proprietary patent-based metrics for its study including "overall innovation (patent) activity, success rate, globalization, and influence." Automotive ranked third in the number of companies on the list (8), behind semiconductor and electronic components (23) and computer hardware (11).
