It is reported that the plaintiff Ren Xiaoping and Sun Jie requested the court to order Apple to stop selling, promising to sell the infringing products 'iPhone7 (32G)' and 'iPad (WI-FI, 32G)' tablet computers that infringed the plaintiff’s patent rights, destroying all stocks. Infringement products, and require the joint compensation of plaintiff economic losses totaling RMB 1 million.
At present, the case has completed the delivery of the defendant and is still within the time limit for proof.
Ren Xiaoping, Sun Jie owns the invention patent titled 'secondary lithium ion battery or battery pack, its protection circuit and electronic device'. The two plaintiffs believe that the battery used in Apple products uses this patented technology to make the original battery. The shortcomings of poor battery life can be greatly improved. With the advantage of large battery capacity, it will be in a more favorable position in the market competition and bring higher profits to it. Therefore, it was sued to the Beijing Intellectual Property Court.
According to published data, the patent was published in April 2003. It mainly provides a new method for improving the capacity, average working voltage and specific energy of secondary lithium-ion batteries or batteries. By properly adjusting positive and negative materials according to theoretical capacity Calculating the ratio and appropriately increasing the charge limit voltage can substantially increase the specific energy and the average operating voltage of the secondary lithium ion battery without affecting the battery cycle performance. Meanwhile, the present invention also provides a secondary lithium ion battery or battery using the method. Group, protection circuit for the secondary lithium ion battery or battery pack, and an electronic device using the secondary lithium ion battery or battery pack using the protection circuit.
The plaintiffs Ren Xiaoping and Sun Jie believe that battery technology is the basic guarantee for large-screen smart phones to achieve various functions and is a technical bottleneck. The involved patents provide a novel and effective way to increase the specific energy of secondary lithium-ion batteries or battery packs. The method of average working voltage. This patent is the basic invention patent of the second generation high voltage lithium-ion battery, and it is the key basic patent of China's key industry. The patent of this patent has also been patented in the United States, Japan, and South Korea.
The Beijing Jingzhou Science and Technology Intellectual Property Judicial Identification Center identified the batteries used in the iPhone 7 and iPad tablets purchased by the plaintiff, and the battery protection circuit fell into the protection scope of the involved patents.
