Panasonic Wins the Case Brought by Dyson Regarding Nanoe EH-NA0G Hair Dryer

Osaka, JapanPanasonic Corporation (Panasonic) announced today (April 27, 2023) that the Tokyo District Court (“the Court”) has rendered judgement (“the Judgement”) to dismiss all claims by Dyson KK (Dyson) relating to the June 9, 2022 case that Dyson brought against Panasonic regarding Panasonic’s EH-NA0G Hair Dryer (“the Case”).

Dyson filed the Case, seeking an injunction against advertisement of Panasonic’s nanocare EH-NA0G Hair Dryer. Upon filing, Dyson officially stated that it was confident that hair dryer advertisements related to the effects of nanoe technology on hair were misleading to consumers, and submitted test results supporting this claim as evidence to the court.

In today’s Judgement, the Court points out that the tests were conducted under inappropriate conditions and the results from them cannot be relied upon, and as such it could not conclude that the data proved Dyson’s claim that Panasonic’s advertisements were misleading to consumers. The Court concluded that Panasonic’s advertisements do not violate the Unfair Competition Prevention Act.

Panasonic will continue to convey accurate information about the value of our nanocare Hair Dryer series to our customers in compliance with all relevant laws, regulations, and guidelines.
