Creator controversy
USB flash drives were invented by Amir Ban, Dov Moran and Oron Ogdan, all of the Israeli company M-Systems, who filed US patent 6,148,354 in April 1999; however, the patent describes a product that has a cable between the memory unit and the USB connector. IBM Patent Disclosure RPS8-1999-0201 from September 13, 1999 by Shimon Shmueli accurately describes the USB flash drive. IBM partnered with M-Systems to bring the product to market. Shmueli was later an expert witness for M-Systems and as part of his testimony in the Singapore court presented the IBM disclosure and evidence to the fact that he invented the USB flash drive. M-Systems’ product, developed by a team led by Dan Harkabi, and named the DiskOnKey, was announced in September 2000. Competing claims have been made by a Singaporean company Trek Technology and a Chinese company Netac Technology, but based on patents that post-date M-Systems’. Both Trek Technology and Netac Technology have tried to protect their patent claims. Trek won a Singaporean suit, but a court in the United Kingdom revoked one of Trek’s UK patents. While Netac Technology has brought lawsuits against PNY Technologies, Lenovo, aigo, Sony, and Taiwan’s Acer and Tai Guen Enterprise Co, most companies that manufacture USB flash drives do so without regard for Trek and Netac’s patents. Pua Khein-Seng from Malaysia claims to have incorporated the world’s first single chip USB flash controller. He is currently the CEO of Phison Electronics Corp, which is based in Taiwan.
