The case, originally against almost 50 companies, requested the commission to ban US imports of infringing products. SanDisk claimed these to include flash memory controllers, flash drives, memory cards and media players, which it felt infringed on its US patents 6,426,893, 6,763,424, 5,719,808, 6,947,332 and 7,137,011. Of these, all but two patents were dropped from the investigation, leaving four claims from the two remaining patents under question. A finding of no violation was made in April 2009, followed by a request for review in May. The review period ended last month, and the USITC has now made its decision known.

Since its launch in December 2007, more than half of the respondents named in the case had been removed due to settlement agreements, consent orders, withdrawal of allegations and defaulting through failure to respond. The remaining respondents included well-known brands such as Apacer, Dane-Elec, Imation, Kingston Technology, LG Electronics and Transcend. In a document issued last Friday entitled "Notice of Commission Final Determination of No Violation of Section 337; Termination Of Investigation", the USITC states its determination that no violation has been found by the remaining respondents, and that its investigation has been terminated.
