[THE INVESTOR] British home appliance maker Dyson has filed a lawsuit against LG Electronics at a local court, industry sources said on July 25.

According to the sources, Dyson sued LG at the Seoul Central District Court, saying LG’s advertisement for the Cord Zero A9 cordless vacuum cleaner exaggerated performance and misinformed users.

The latest move comes as a follow-up to the injunction filed by Dyson in November last year, which was turned down by the local court in April.

The British firm claims that LG’s advertisements that describe the rotation speed of the motor as “16 times faster than that of a jet engine” is inaccurate.

LG said it has not received any notification concerning the lawsuit so far, but said it will actively respond to the case.

The suit is the latest in a string of legal disputes between the two companies.

“In the Korean market for cordless vacuum cleaners, LG and Dyson account for some 40 percent share each, and are battling neck-and-neck,” a market watcher said, claiming such fierce competition has caused the two firms to become more sensitive about each other.
