In this Statistical Report, the U.S. granted patents with origins in the seven major foreign countries (Japan, Canada, Italy, China, India, Russia, and Brazil) in all years were researched. Japan had the most numbers of granted patents among the seven countries. These seven countries occupied more than half of the foreign origin granted patents and more than a quarter of the total U.S. granted patents.
Figure 1. The numbers of U.S. granted patents by origins in the seven major foreign countries (Japan, Canada, Italy, China, India, Russia, and Brazil) in all years.
(From Left to Right: Japan, Canada, Italy, People’s Republic of China, India, Russian Federation, Brazil)
Fig. 1, displays the numbers U.S. granted patents by seven foreign origins, particularly Japan, Canada, Italy, China, India, Russia, and Brazil in all years (before and after 2002 until 2015). Japan had the highest number with more than 80,000 granted patents, which was more than the other six countries combined. The other six countries all had less than 10,000 granted patents; Canada, Italy, China had relatively higher numbers while India, Russia, Brazil had even lower numbers.

Fig. 2 shows U.S. granted patents with origins in the seven countries made up more than half of all the total foreign origins. Similarly, the seven countries had more numbers of U.S. granted patents than other foreign countries combined.
Figure 3. The percent share (%) of each of the seven foreign origins, and other foreign origins, U.S. origin in the total U.S. granted patents.
As Fig. 3 shows, patents of U.S. origin had a bit more than half of the granted patents in all years. The seven countries (Japan, Canada, Italy, China, India, Russia, Brazil) had a bit more than one quarter of the total, in which Japan itself occupied one fifth of the total patents. Other foreign origins had the rest of the total shares, about a quarter.
Discussion and Conclusion
Of the seven foreign countries, Japan had the highest number of U.S. granted patents, followed by Canada and Italy (Fig. 1). Those three countries are developed countries, which may answer why they had more U.S. granted patents in all years. Since China, India, Russia and Brazil are emerging countries, it makes sense that they would have more patents in recent years; but in all years together, they definitely had fewer patents.
Regarding all of the foreign origin U.S. granted patents, the seven countries had more than half of the total (Fig. 2); and of all the U.S. granted patents (foreign and U.S. origins), the seven countries had more than a quarter of the total (Fig. 3). Thus, the selected seven countries, which include both major developed and emerging countries, are essential contributors of U.S. granted patents.
