????6. Toshiba

????Patents earned: 2,608

????Representative patent: "Semiconductor Device"

????Country: Japan

????With tech conglomerate Toshiba clocking in at sixth place, Japanese companies retain a strong showing on IFI Claims' 2014 list—despite Japan's share of U.S. patent grants having declined 2.5% over the past five years. (While the U.S., Korea and China's share of patent grants continues to grow steadily—China's share actually doubled, though it still only accounts for a meager 2% of the year's total—Japan and Europe's shares are in decline. Cady attributes this trend to "general belt-tightening in those markets.") The company's most popular patent category is semiconductor devices, where one may find the provocatively titled patent "Semiconductor Device." The filing mentions its purpose as producing a device "improved both in data retention characteristics and read characteristics."
