Editor’s note: This story is an updated version of the report that appeared in the June print issue of IEEE Spectrum.

On 7 June, consumer electronics firms Fujitsu Ltd. of Japan and Samsung SDI Co. Ltd. of South Korea, announced that they have ended a bitter patent dispute over the technology behind their plasma displays. Both companies have dropped lawsuits filed in the United States and Japan, and Fujitsu has withdrawn its request that its rival be barred from selling its products in Japan.
