Kawasaki 's bullet train: China's high-speed train patents violated contracts signed between Japan and China
China has rejected Japanese accusation that it violated intellectual property rights concerning high-speed rail technology for which the Communist State has sought international patents.
Stating that the Japanese accusation displayed a "lack of confidence," spokesman for China's Railways Ministry Wang Yongping said on Thursday that China developed the technology independently.
His remarks came after Tadaharu Ohashi, Chairman of Japan's Kawasaki Heavy Industries Ltd., said last week that the company would take legal action if China's high-speed train patents violated contracts signed between Japan and China.
State-run Xinhua news agency quoted Wang as saying that the China CNR Corp Ltd. and the China Academy of Railway Sciences had been filing patent applications abroad since 2009.
Earlier, a top official of the Ministry's Transport Bureau had told Chinese media that Beijing had filed 21 applications under the Patent Cooperation Treaty.
The applications relating to train assembly, hulls and bogies (part of the suspension system) were filed in the United States, Brazil, Europe, Russia and Japan.
"All the high-speed rail patents that China is applying for abroad have been developed independently, and they do not infringe on other countries' high-speed rail patents. China will not claim anything that does not belong to it. However, it will not give up the right to patent its innovations because of irresponsible remarks by others," Bureau Director Li Jun said.
Kawasaki had transferred its technology for a 200-km/h train to China in 2004 and the Qingdao Sifang Co Ltd., a subsidiary of CSR Corp Ltd., in partnership with Kawasaki produced the train CRH2 in China.
CSR later developed its own 300-350 km/h train and the CRH380A train with a designed top speed of 380 km/h.
"The strong reaction of some Japanese, without even knowing exactly what patents China is filing for, shows a fragile state of mind and a lack of confidence," Wang said.
Japanese Foreign Minister Takeaki Matsumoto had also taken up the issue with his Chinese counterpart Yang Jiechi during his visit to Beijing on July 4.
Wang said China "absorbed" foreign technology but also "innovated".
Compared to the CRH2 train, produced with Kawasaki technology, the CRH380A train for the Beijing-Shanghai route operates at much higher speeds.
Ridiculing claims that China pirated technology from Japan's bullet train 'Shinkansen,' Wang said the Shinkansen and the Beijing-Shanghai high-speed railway were on two different levels.
There were huge differences in terms of speed, comfort and technology.
However, he said China was willing to "offer" technological help to Japan in accordance with international laws and trade rules for its proposed high-speed lines totaling 870 kilometers.
