Chinese enterprises are keen to take the lithium iron phosphate line

The advent of lithium iron phosphate has not been long in the technology, from its birth, the patent would not stop fighting.
First by academics known as the “Father of lithium iron phosphate,”dell laptop battery University of Texas professor of American and Japanese NTT patent battle between the latter company in Taiwan, “Huaqianxiaozai” buy lithium iron phosphate battery patent is licensed, the same as between Europe and the United States, lithium iron phosphate blows patented technology. December 9, 2009, the European Patent Office ruling to revoke the right granted to the University of Texas lithium iron phosphate of the European patent ownership.
“This decision protects the interests of many European companies, dell Inspiron 500m battery, dell Inspiron 510m battery, dell Inspiron 600m battery, dell Latitude D500 battery, if the revocation of the patent, European companies will be free to develop and use iron phosphate lithium battery technology.” Zhang Chu said they now want China to follow the example of the European Patent Office’s decision to protect domestic industries.
Relative experts worry, the domestic lithium battery companies who are relatively optimistic about this issue.
Zhejiang, a lithium battery manufacturer that now restrict iron phosphate lithium battery development bottleneck, not the patent issue, but technology is not yet mature, and how to achieve industrialization. “Although there are many interested customers lithium iron phosphate, but few people ordering large quantities directly, but only a few groups to do the battery test. Lithium iron phosphate battery technology is not mature, the performance is not stable, large Most customers only hold a wait and see attitude. “The manufacturer said.
Some analysts believe that Chinese enterprises are keen to take the lithium iron phosphate line,dell Latitude D500 battery, but the accumulation of patents and technology still lag behind the United States, Japan, and Taiwan. Now claims to reach production capacity of 2 million metric tons, but subject to the technology and processes, product quality is not an edge, leading to actual production is not high, but able to meet the power needs of high-end materials, lithium iron or China Taiwan still imports from abroad.
University of Texas patent on lithium iron phosphate, in the United States, Japan, Germany, Italy, Britain, France, and Canada has applied for patent protection. While in the European patent is revoked, but the use of the patent of the product, if exported to the United States, risks remain.
Sha Yong Kang proposed to fundamentally resolve the problem, the following two aspects: First, out of the current electric, hybrid, fuel cell group, further developing the technical route, from the technical concepts and principles of the new kitchen. Thoroughly integrated inventory or survey of existing domestic lithium battery research and patent strength, further develop its own technology of lithium batteries.
“Lithium iron phosphate international patent lack of an answer is not solved, we will be in the industrial chain is still in low-end passive position.” Sha Yong Kang said.

Lithium iron phosphate material patent dispute
In 1997, by academics known as the “Father of lithium iron phosphate,” University of Texas professor on lithium iron phosphate technology-related patent application.
In 1999, patent application is approved. Because of the patented invention for the post behavior, ownership of the patent belonging to University of Texas.
Japanese telecommunications company (NTT) has proposed,dell Inspiron 600m battery, in 1996, they had already reported the olivine structure of lithium-ion cathode material, patents should belong to them.
In order to compete for ownership of the patent in 2001, the University of Texas and its business license of Quebec water company sued NTT to illegally steal technology secrets. Ultimately, the case settled out of court closed to. U.S. University of Texas admitted “NTT is not stealing its technology secrets”, but NTT was forced to the lithium iron phosphate materials have patents licensed to the University of Texas. In addition, NTT has to pay 30 million U.S. dollars of the settlement.
Japanese companies in the patent war victory, the Quebec Hydro, Phostech company,dell Inspiron 500m battery, dell Inspiron 510m battery, dell Inspiron 600m battery, dell Latitude D500 battery, in turn targeting Taiwan. Taiwan has thousands of large and small, battery manufacturers, many companies did not receive patents. In order to avoid potential patent disputes, some Taiwan companies have chosen the “Huaqianxiaozai” to handle the matter. Taiwan’s powerful energy companies through the purchase of lithium iron phosphate way to get a patent is licensed.
China’s DVD patent loss of business
Occurred in the last turn of the century’s DVD patent fee dispute, the transnational corporations with “the exercise of intellectual property” in the name of China’s DVD business to charge royalties 3 billion yuan and is expected to levy royalties 20 billion yuan; dell Inspiron 510m battery, China DVD business, because there is no defensive measures, only to pay large fees.
June 1999, when the DVD began to pop in the market era, 6C (including Hitachi, Panasonic, JVC, Mitsubishi, Toshiba, Time Warner) announced that “DVD Patent Joint License” statement calling on all of the world production of DVD manufacturers must to them to buy “patent license.”
April 19, 2002, China Audio Industry Association in two years time, after many negotiations, finally signed an agreement with the 6C to provide Chinese manufacturers export a platform for every DVD player to its four U.S. dollars to pay royalties. Subsequently, the Association and the 3C (Philips, Sony, Pioneer) have entered into an export platform for every DVD player to pay 5 dollars to its royalties agreement.
With DVD sales of the international market price continued to fall, when the U.S. market retail price of DVD machines only 30 to 40 dollars,dell Inspiron 500m battery, Chinese companies export a DVD for each machine would pay about 12 U.S. dollars respectively royalties. Domestic DVD player almost unprofitable export business, many companies no longer produce DVD products or close down.
