With the use of mercury-containing button battery volume and the increasing volume of waste, waste batteries, mercury pollution of the environment have long plagued the human life. China has independently developed by the mercury-free button battery patent, has passed the edge of Lenovo 3000 C200 battery life and death are in the 8th year.

The patent has been twice the national patent review committee declared invalid. Beijing Municipal Higher People’s Court of Final Appeal ruling overturned two patent review committee’s decision. In September 2009, the Patent Reexamination Committee announced a third of mercury-free button battery patent is invalid, the patent owner of the third patent review committee to resort to the courts. The case is currently pending under the Beijing Municipal No. 1 Intermediate People’s Court.

? patented technology is no longer a secret at all

Why was there for the mercury-free button Lenovo 3000 Y510a battery have been repeatedly declared the patent invalid, the reporter interviewed a number of contacts of national patent review committee and in accordance with the requirements of the other fax an outline of the interview, but last Friday, the Patent Reexamination entrusted with the inconvenient interview and refused to interview with reporters.

According to reports, in accordance with our rules of patent protection, patent protection is a patented invention, the disclosure of patented technology for the premise that the inventor in patent applications at the same time, to declare its own patented technology secrets made public. That is, if the patent is declared invalid, the inventor is also no longer a secret at all, other manufacturers can not put any development funding for free public use of the technology of Lenovo IdeaPad Y530 battery, rather than held accountable under the law does not assume any liability.

? 10-year patent protection period is about to expire

Mercury-free button on the battery patent license notice, after a further round of the battery businesses and individuals began to Patent Reexamination Board to submit a request to declare the patent invalid mercury-free button batteries.

May 31, 2004, the National Committee of the patent reexamination of enterprises according to two Lenovo IdeaPad Y730 battery apply to mercury-free button batteries do not have the creativity, and declared all of the patent is invalid. The Guangdong companies to court Leader, December 20, 2005, the Beijing Municipal Higher People’s Court of Final Appeal ruling committee loses patent reexamination, the court found that mercury-free button batteries all the valid patent.

June 19, 2009, the State Patent Reexamination Committee make a decision the third time, to mercury-free button batteries do not have the creativity, and declared all of the patent is invalid. In October 2009, Guangdong New Leader’s third patent review committee sue in court, asked the court to revoke the patent review committee’s decision null and void. At present, mercury-free button Lenovo 3000 G230 battery 10-year patent protection period is about to expire, the ultimate fate of the concern of the patent.

? “judicial finality” Why is it difficult to finality?

An interview with intellectual property experts. Experts in the field, the original court in Beijing, a tribunal of senior judges to know middle Guang-Liang Zhang told reporters before the WTO, the case involves a utility model patent license and maintenance procedures, are “administrative finality”, that National Patent Reexamination Board makes its decision direct the force of law, the parties have no right to bring Lenovo IdeaPad U330 battery administrative proceedings.

Keeping with international standards, China’s “Patent Law” was amended accordingly, and change “executive finality” for “judicial finality”, that is made by the administrative department of intellectual property satisfied with the ruling, the parties have the right to bring an administrative lawsuit. The final decision by the court. Then the “judicial finality” Why is it hard to finality? In this regard, Guang-Liang Zhang said the cycle of litigation for patent disputes, the question, “the patent laws,” the experts, when he was raised, but because of the final amendment of the Act did not make an explicit provision led to a patent lawsuit is also 3 inconclusive case. Mr. Zhang, that under such circumstances, how to protect the rights of the patented invention is indeed worth studying.

Production equipment

In addition, because crystalline silicon cells a longer time in China’s development, manufacturing equipment, mature technology, the entire industry, 80% of the equipment from domestic purchases, so a lower invested capital. The thin-film battery due to the short development time, production equipment, there are still a lot of core technology still has to import, for example, large-scale general-purpose production equipment capable of manufacturing the world is only three, namely the United States, Applied Materials (AMAT), the Swiss Oerlikon (Oerlikon) and Japan’s ULVAC (ULVAC), while thin-film battery the entire production line is generally the price of crystalline silicon cell Lenovo 3000 N500 battery production line three times more than the price of a single device a number of crystalline silicon cells and even 10 times the production equipment, coupled with thin-film battery technology, fast updates, equipment out of the high rate of capital investment too.

The impact on the environment

In addition to these advantages, the natural elements of high-purity polycrystalline silicon as raw material for crystalline silicon cells have the advantages of human non-toxic harmless, while the thin-film battery in the production process is released to the environment pollution caused by nitrogen trifluoride. That might also be characterized as crystalline silicon cells Lenovo IdeaPad Y510 battery to further enhance the market share has laid a solid foundation.

Generally speaking, the past is in the snatch silicon thin-film battery battery market, is now the situation is reversed, the original thin-film battery on the small living space would be further robbed crystalline silicon cells. Crystalline silicon cells is still the mainstream market, can not be replaced.

In 2008, a global financial crisis made it as a solar PV industry, polysilicon-based raw material prices fall from the financial crisis before the close to 500 U.S. dollars / kg rapidly dropped to 60 U.S. dollars / kg, which rely on crystalline silicon to crystalline silicon raw materials battery industry has brought good, greatly enhancing its expanding market share advantage.

In the past few years, due to polysilicon prices soared, making the total cost of crystalline silicon Lenovo 3000 G530 battery cells in the crystalline silicon material costs accounting for as high as 56.2%, becoming too heavy a burden manufacturers, China’s corporate profits have taken a hit. In this case, a number of manufacturers in order to get rid of the crystal on silicon raw materials began to have entered the field of thin-film batteries. However, in polysilicon prices fell sharply after the thin-film battery manufacturers are the days became dark, we understand that some companies are building thin-film battery project progress has slowed, a number of planned projects have been canceled. In this regard, concerned that the market pick up in the new round, the crystalline silicon cells manufacturers, may be given more opportunities, thin-film batteries will be at a disadvantage in the competition, this is because the increasing prices of raw materials close to the case, crystalline silicon cells than thin-film batteries in many respects an advantage.

Photoelectric conversion efficiency

At present, the world’s most advanced crystalline silicon cells for solar Lenovo Ideapad Y430 battery conversion rate of 22%, domestic crystalline silicon cells have reached conversion rate of 17% to 19%, while international industrial production on the three kinds of thin-film batteries (silicon thin-film solar cells, copper indium gallium selenide thin-film solar cells, cadmium telluride thin-film solar cells), the even higher conversion rate of cadmium telluride thin-film solar cells and copper indium selenide thin-film battery, conversion rate is only 11% and 12% , the domestic is only about 6%. In contrast, crystalline silicon cells superiority is obvious. Domestic industry leader Shi Zhengrong at the Third International Conference on Photovoltaic Solar Energy said that in the current domestic thin-film solar cell conversion rate is only around 6% of the cases, it is difficult to compete, and crystalline silicon cells. The long run, the conversion efficiency of thin-film solar cells must reach 10% to remain competitive.
