From 1998 to 2000, many companies claimed that they were the first to invent USB flash drives. Include China Netac Technology, Israeli M-Systems 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 17225.6) was officially authorized by China National Intellectual Property Administration. This patent fills the gap of invention patent in the field of computer storage in China for 20 years. The acquisition of this patent right has caused a great shock to the entire storage industry.
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, Netac entrusted American lawyer Morgan Lewis to file a lawsuit in the eastern federal district of Texas.
The court filed a lawsuit accusing PNY Company of infringing Netac's U.S. patent (U.S. Pat.No. US6829672).
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 inventor of the U disk.
