Many people know that China's chips are stuck by developed countries, but do you know?Many basic materials are still stuck in our necks, such as a small magnet, and we in China have actually paid Japan patent fees for decades. In 1982, Japan's Sagawa Masato invented the first NdFeB magnet, which is known as the NdFeB magnet of industrial blood, which is also called Magneto. This material must not be underestimated, it is the most valuable product of China's rare earth, new energy vehicles, intelligent manufacturing, industrial robots, car horns all need to use this rare earth magnet.
After the invention of NdFeB magnets by the Japanese, they began to apply for patents in various developed countries around the world, including the United States and Europe, which led to the result that anyone who wanted to use this material had to buy his patented magnets from Hitachi Metals. And do you think that the patent given to you by Hitachi Metals is to teach you how to make this material?No, he just allows you to produce, allows you to sell, and even in order to maintain the strong position of his patents, Hitachi Metals once launched a 337 investigation in the United States in 2012, when 29 large international and domestic enterprises, including 4 magnetic factories in China, were all sued, the purpose is to let the world know that his patent is very effective, and he will take legal action to protect his patent.
Therefore, in order not to cause unnecessary trouble, many large company customers would rather pay a higher fee to buy products produced by patented magnetic material manufacturers. In the rare earth magnet industry, if the customer says that he needs a patented magnet, we know that the customer's requirements are still very high, because only large customers, as well as brand customers, are willing to pay for intellectual property rights, and Hitachi's patents are still valid until now. There are a total of 8 companies in China that have Hitachi's patent authorization, and these 8 companies almost occupy 70 80% of the entire high-end magnetic material market, so if your company's products are to be exported, to such a large customer in the European and American markets, you must be careful about the patent issues in this, otherwise there will be a big trouble.
Pay attention to Jiangxi Sanfu Iron and share more knowledge in the field of rare earth permanent magnets.
