KBS News reports on alleged fraud in technology development at SeeDevice, a U.S.-based quantum sensor developer, in a broadcast from Aug. 25, 2024. Captured from KBS News

U.S. tech firm SeeDevice has filed a defamation lawsuit against Korean Broadcasting System (KBS) and its U.S. affiliate, KBS America, accusing them of inaccurate reporting on its technology that cost the company a major commercial opportunity and wasted years of research.

The company said last week that a trial has been set at the U.S. District Court for the Central District of California to begin in January 2027.

The case stems from an August 2024 KBS report alleging the Korean government decided to retract its research grant after finding the company's technology to be fraudulent.

At the center of the dispute is QMOS, SeeDevice's proprietary sensor technology designed to simultaneously detect visible light as well as X-rays, ultraviolet and short-wave infrared wavelengths invisible to the human eye, without the specialized materials and processes that many conventional infrared sensors require.
