Mitsubishi Electric takes patent crown for second year

TOKYO -- Mitsubishi Electric topped a ranking of patents by asset value for a second year running, according to Tokyo-based patent analysis and research company Patent Result. 

Mitsubishi Electric came in first owing to the popularity of its in-vehicle equipment, electric inverters and remote control system that switches air conditioners into energy-efficient mode.

The ranking is based on patents registered with the Japan Patent Office in fiscal 2015.

While Mitsubishi Electric's tally of registered patents fell by 15.7% on the year to 3,394, the company still came out on top.

Not much change was seen in second-to-fourth places from the year earlier. Toyota Motor came in No. 2 thanks to its control systems for hybrid and electric vehicles as well as its driver assistance systems. Panasonic's patents for LED lights, battery chargers, and electricity distribution systems brought it the No. 3 spot. Canon placed fourth.

Honda Motor took fifth and Konica Minolta was sixth, leaping from the 10th and 15th spots, respectively. Honda's easily removable battery for two-wheeled vehicles drew high scores. And Konica Minolta's flexible OLED element, which balances transparency and conductivity, also won praise.
