I read most of the QD Vision file. It didn't go inactive, per se, rather QDV abandoned the application after the USPTO rejected it the second time. It was rejected because QLED was "merely descriptive" and that "QLED is used interchangeably with quantum dot light emitting diode." (emphasis is mine)

QDV argued that they should get the QLED trademark because the common definition of QLED ("QLED is comprised of quantum dots sandwiched between two electrodes in order to emit light") was not what they were doing.

Applicant’s goods refer to a display, achieved by an optical converter which changes the color of light to allow for better color saturation and color rendering. Put simply, Applicant’s goods are electronic displays with brighter, sharper colors. This is a clear distinction between the Examiner’s interpretation of the goods and the actual goods.

To that, the USPTO cited a patent (8,363,307) dating back to 2008 which included "A quantum light emitting diode (QLED) is constructed by placing, in the output path of an LED, an optical converter incorporating quantum dot particles."

That's exactly what Samsung is doing. Not sure how LG gets by that - at least not on products to be sold in the US.
