Korea Trade Commission launches investigation into patent infringement of uninterruptible power supplies

The Trade Commission of the Ministry of Trade, Industry and Energy of South Korea held its 454th meeting on the 21st and announced that Japanese company TMEIC had applied for a Japanese company A, another supplier in South Korea.
The company announced that it would begin an investigation into the infringement of the patent right for an uninterruptible power supply that it has developed. An uninterruptible power supply is a device that can stably supply power to a load even if an abnormality occurs in the input AC power supply.
In addition, the Trade Commission has determined in its investigation of the "infringement of patent rights for secondary batteries for smartphones" that the applicant's patent rights have not been infringed and that this does not constitute unfair trade practices.
The investigation into the infringement of patent rights for secondary batteries for smartphones was requested earlier by Semiconductor Energy Laboratory, a Japanese company that manufactures smartphones in China and supplies them to South Korea.
The investigation targeted Chinese companies and Korean companies that import and sell them. The Trade Commission conducted a document investigation, sample analysis, and technical briefing sessions to investigate whether there was any patent infringement, and concluded that there were no unfair trade practices.
In addition, the FTSE concluded that the applicant was not included in the investigation into the "Lubricant Additives Patent Infringement" that it had determined to be a patent infringement on January 20, 2017.
The FTSE said it had re-determined that Infinium Korea's patent was non-infringing because its patent was invalid.
The company also decided to launch an investigation into the "tent and sleeping bag trademark infringement" that was allegedly alleged to have occurred.
