Also in 1999, Shimon Shmueli, an engineer at IBM, submitted an invention disclosure asserting that he had invented the USB flash drive. A Singaporean company named Trek 2000 International is the first company known to have sold a USB flash drive, and has also maintained that it is the original inventor of the device. Finally Pua Khein-Seng, a Malaysian engineer, has also been recognized by some as a possible inventor of the device.
