Patents for more than 200 million melamine production methods involved were maintained in force

Recently, the Patent Review Committee of the State Intellectual Property Office made a decision on the application for invalidation of patents for inventions of "energy-saving and energy-saving gas-phase quenched methamine production system and its process" and "combined heat exchanger and fluidized bed reactor", both of which were maintained in force on the basis of the revised claims. These two invention patents have been highly concerned by the industry because of infringement lawsuits involving more than 200 million yuan.recently, the Patent Review Committee of the State Intellectual Property Office (here called the Patent Review Board) on the "energy-saving gas-phase quenching of the production system and its processes" (patent number: ZL201110108644.9) and "Combined heat exchanger and fluidized bed reactor" (patent number: ZL201010216437.0) invention patent invalidity claim case to make a decision to review, on the basis of the revised claims to maintain the validity of both patents. These two invention patents have been highly concerned by the industry because of infringement lawsuits involving more than 200 million yuan.At the end of 2016, Beijing Jingjing Technology Co., Ltd., a joint subsidiary of Sichuan Jinhuan Serry Chemical Co., Ltd. (the following) and its subsidiary, Beijing Jing Technology Co., Ltd. (the "Jinjing Technology"), filed a lawsuit with the Guangzhou Intellectual Property Court, arguing that Shandong Hualu Hengsheng Chemical Co., Ltd. (the "Hualu Hengsheng") Ningbo Chemical Research and Design Institute Co., Ltd. (called Ningbo Chemical Research Institute), Ningbo Far East Chemical Group Co., Ltd. (formerly known as Far East Group) and natural person Yu Mingda (Golden Elephant Serai former chief engineer) jointly infringed the patent rights of the two inventions, a total of 135 million yuan claimed. (Reporting in the 8th edition of this newspaper on May 3, 2017 In August 2017, Jin XiangSery jointly sued the Chengdu Intermediate People's Court for 98 million yuan for infringement of trade secrets by the company's former chief engineers, Yu Mingda and Hualu Hengsheng, Ningbo Chemical Research Institute and Far East Group, seeking 98 million yuan in damages.claims in both cases amounted to $233 million.
in the 2008 "Sanlu milk powder" incident, illegal elements by adding melamine to raw milk, in order to improve the protein content of dairy products. At that time, melamine had been a pleasant change of color. However, melamine is in fact a very important and widely used chemical raw material. In daily life, from furniture products widely used adhesives to tableware, fire paint, RMB waterproof materials ... Melamine is used as raw material for the production and manufacture of various types of products can be said to be everywhere.industry insiders, the main component of melamine is nitrogen, the main raw material for the production and manufacture of melamine is nitrogen-rich urea. China is the world's largest urea producer, urea production is large and low price, rich urea resources make China's production and manufacture of melamine has a greater advantage.It is understood that pressurized gas phase quenching method melamine production technology by the Golden Elephant Serry technical team invested nearly 100 million yuan, lasted more than ten years of successful research and development, with energy conservation, environmental protection and other outstanding advantages, become the most important melamine production technology. Through the implementation and application of these two patents, China's melamine industry has developed rapidly, rapidly increasing production capacity to total production capacity accounted for more than 70% of the world. Because the use of these two patents to produce melamine has "high quality, high output, low cost" and other obvious advantages, foreign enterprises were forced to close production lines, so that China in a short period of time to become a veritable global "melamine" production of the first large country. With the production technology of pressurized gas phase quenching and cooling, the golden elephant Serry has emerged in the melamine industry, with an annual output of more than 300,000 tons, making it one of the largest melamine production enterprises in the world.July 2012, "combined heat exchanger and fluidized bed reactor" was granted a patent for inventions in China, and in September 2013, "energy-saving gas-phase quenching and cooling of the production system and its processes" was granted a patent license for Chinese inventions. At present, the two patents have been in the United States, Japan, South Korea, Europe and other countries and regions have been granted.2014, the patent "Energy-saving gas-phase quenching methamine production system and its process" was awarded the 16th China Patent Excellence Award jointly by the State Intellectual Property Office and the World Intellectual Property Organization. In addition, he has won the China Nitrogen Fertilizer Industry Association's Special Award for Technological Progress, the first prize for scientific and technological progress in Sichuan Province and the first prize for patents in Sichuan Province.'s lawsuit against Therai, Far East filed a patent declaration against the patents for the two invention patents in August 2017, arguing that they were not novel and creative.
Recently, the Patent Review Board has made a patent invalidity declaration examination decision, on the basis of the revised claims, the Far East Group proposed the reasons for the invalidity declaration are not valid, to maintain the "energy-saving gas-phase quenching and cooling of the production system and its processes" and "combined heat exchanger and fluidized bed reactor" invention patent valid.industry analysis that in patent infringement litigation, the patent right is maintained effective is a stage victory, for the infringement of the determination has laid a solid foundation.
the two patents involving more than 200 million yuan of civil tort litigation, and related to the overall pattern of the domestic melamine industry, it has received great attention. This newspaper will continue to monitor the progress of the case.
