Development history
From 1998 to 2000, many companies claimed that they were the first to invent USB flash drives. Include China Netac Technology, Israeli M System Company and Singapore Trek Company. However, the real patent for the basic invention of U disk is China Netac.
In July 2002, Netac's "Flash Electronic External Storage Method and Device for Data Processing System" (patent number: ZL 99 1 17225.7) was officially authorized by China National Intellectual Property Administration, which filled the gap of invention patents in the field of computer storage in China in recent 20 years.
The acquisition of this patent right caused a great shock to the entire storage industry, including the Israeli M-Systems Company immediately filed an invalid reexamination with China National Intellectual Property Administration, China, which once became a patent dispute that shocked China and foreign countries in the global flash memory field. However, on February 7, 2004, 65438, Netac obtained the basic invention patent of flash disk officially authorized by the US National Patent Office, with the US patent number of US6829672.
The acquisition of this patent right finally ended the struggle. China Netac is the world's first inventor of USB flash drive. On February 10, 2006, American time, Netac entrusted Morgan Lewis Law Firm of the United States to file a complaint with the Federal Court for the Eastern District of Texas, accusing PNY Company of infringing Netac's American patent.
In February 2008, Netac and PNY reached an out-of-court settlement. Netac signed a patent license agreement with PNY, and PNY paid Netac a patent license fee of $654.38+million. This is the first time that a China enterprise has obtained a huge patent license fee in the United States, which further proves that Netac is the global inventor of U disk.
