SANYO SONY BYD has launched an attack to find evidence of positive coping

According to reports, BYD is in favor of SONY before this September 2002, striking one snag after another, the Sanyo Corporation in violation of its battery patent grounds BYD to the Santiago court case is still pending, July 8, 2003, Japan's Sony Corp in advance without any negotiations, Yizhisuzhuangjiang BYD reported to the Tokyo district court, accusing BYD at in 2001 2002, Japan CEATEC exhibition two lithium ion battery, two cases of alleged infringement of patent in Japan, demanding a ban on BYD two lithium ion battery sales in japan. This is the two patents filed in 1988, is a "inside the battery according to the average capacity design gap" (No. 2646657th) of the patent, is a "thickness and the proportion of positive and negative electrode coating material" (Patent No. 2701347th). SONY believes that the two patents are the basic patents of lithium-ion rechargeable batteries.

In the face of two Japanese companies patent attack on both sides, BYD did not flinch. In August 26, 2003, BYD received a reminder to complain, in a short span of 40 days to collect relevant evidence in Japan in October 8, 2003 38, Tokyo district court to submit pleadings and the relevant evidence, denied SONY's patent infringement. Huang Zhanghui, general manager of intellectual property rights and Law Department of BYD, said that there are two strategies for dealing with patent infringement cases: one is that there is no infringement of patent by evidence; the other is that the patent is invalid for the application of two. From October 2003 to March 2004 in recent months, BYD hand actively seeking evidence in the Tokyo district court that he did not infringe SONY patent; on the other hand, BYD secretly seeking evidence to prove that SONY's patent is invalid. After nearly half a year to collect evidence, BYD in March 2004 19 to the Japan Patent Office (JPO) filed a patent invalidation request, asking for the announcement of SONY No. 2646657th and No. 2701347th patent is invalid. At this point, BYD in the infringement case in the attack.

January 25, 2005, the Japanese Patent Office ruled that SONY 2646657th patent invalid. But the lawsuit is not over. In March 2, 2005, SONY appealed to the high court of Japan's intellectual property rights, requesting the revocation of the ruling of the Patent Office of Japan to maintain the validity of the patent No. 2646657th. November 7, 2005, the Japanese Intellectual Property Tribunal verdict, dismissed the appeal of SONY's request to maintain the Japanese Patent Office made the announcement of SONY 2646657th patent invalid ruling. In December 2nd, SONY filed a request for withdrawal to the Tokyo magistrates' court, to withdraw all charges against BYD. BYD has finally won the lawsuit.

BYD's success shows that Chinese enterprises should actively respond to intellectual property cases, safeguard their legitimate rights and interests." Huang Zhanghui said, at present, we found that there is such a case: because Chinese companies do not respond to foreign companies in the report to other importers, the Chinese companies will be inexplicably pulled. Even if Chinese companies actively seek reconciliation, foreigners feel that you are doing something wrong, and actively respond to and win, one can safeguard the interests of the company, and secondly for Chinese enterprises to fight!"
