Which is the biggest bottleneck to constraint the development of NdFeB Magnets industry?

　　Our country has rich rare earth resource, which provides the necessary material conditions for the neodymium iron boron industry's fully development.

　　In recent years, our country bonded NdFeB magnets and Sintered NdFeB magnets yield show substantial growth, and gross has already been higher than in Japan at the beginning of this century, rank the world first, world magnet industry center has transferred from Japan to china.

　　However, we also should see that, because the magne and Neomax hand with neodymium iron boron patents, although China NdFeB magnets manufacturers reached more than 100, but it has only 5 enterprises with the authorized patent, since many manufacturers have no patents, and it will be difficult to export their own products to the Japan, Europe and the United States of America covered with patents.

　　It can be said, the patent limitation has become the biggest bottleneck to constraint the development of NdFeB Magnets industry.
