Why do U disk manufacturers in the world have to pay China companies like Netac?

Every time a U disk manufacturer sells a U disk, he has to pay the patent fee to Netac Technology Co., Ltd ... Deng Guoshun, the founder of Netac Technology, is an excellent student. 1985 entered Sun Yat-sen University to study computer. Go to China Academy of Sciences for a master's degree after graduation. From 65438 to 0993, I worked for Singapore Software Company. 1999, Deng Guoshun returned to China to establish Netac technology company, and filed a patent application for U disk in110/0. Its full name is flash memory electronic external storage method and device of data processing system. On July 24th, 2002, this patent was awarded by China National Intellectual Property Administration, which means that Netac Technology was officially recognized as the inventor of U disk in China.

At a science and technology exhibition in Germany in 2003, another technology company, JMTek, also announced that it had a total share of over 50% in the United States and established a joint venture with Netac Technology. From June 5438 to February 2004, the US National Patent and Trademark Office also authorized Netac USB flash drive. USB flash drive was invented by China Netac Technology Co., Ltd. ..

At that time, Netac and JMTek's USB flash drives were the best-selling products. When the network is not so developed, the USB flash drive is just for office needs. Netac has been recommended by IBM since 2000. In addition, Netac not only owns the technical patent of U disk, but also owns the trademark patent of U disk.

In other words, the word USB flash drive also represents a brand of that era. Others can call their products USB flash drives, USB flash drives, or storage disks, but not USB flash drives. At that time, you may not have bought the brand Netac, but the products called USB flash drives are all Netac products. You must pay the patent fee to Netac.
