he had sent the prototype machines, drawings, and confidential information to Amway as part of a contract in April 1984. In January 1985, Amway produced the CMS-1000, a machine which was very similar to the Dyson design. Less than a month later, Dyson sued Amway. Dyson and Amway settled the lawsuit in 1991, becoming joint licensees. Hoover In 2000, Dyson sued Hoover for patent infringement of Hoover's Triple Vortex, which was using cyclonic technology and patents similar to Dyson's Dual Cyclone, Dyson won against Hoover and accepted the settlement offer of £4m plus £2m in legal costs. Excel Dryer On 5 December 2012, a lawsuit by hand dryer manufacturer Excel Dryer was filed against Dyson, claiming that Dyson's advertising comparing the Airblade to the Excel Dryer Xlerator was deceptive. Dyson's advertisements stated that the Xlerator produced twice as much carbon dioxide, was worse for the environment, and cost more to operate than the Airblade. Excel Dryer claimed that Dyson was falsifying its comparisons by submitting a 20-second dry time for the Xlerator to the Materials Systems Laboratory at the Massachusetts Institute of Technology, rather than Excel Dryer's tested 12 second dry time, thus inflating energy consumption figures in the Airblade's favour. LG In October 2015, LG sued Dyson in Australia over an advertisement claiming the V6 vacuum to have "twice the suction power of all cordless vacuums." LG stated their vacuum Cord Zero Cyking provides 200 watts of maximum suction power, twice that of the Dyson V6. LG dropped the lawsuits after Dyson said it would accept LG Electronics' request. The British company said it would remove two advertisement claims – "The most powerful cordless vacuums" and "Twice the suction power of any cordless vacuums" – from all electronics outlets in Australia by December 2015. In November 2017, Dyson took legal action against LG in South Korea for false advertisement of its Cord Zero A9 cordless vacuum cleaner. Dyson claimed the ads exaggerated the vacuum's performance with statements such as "rotation speed of the motor ... 16 times faster than that of a jet engine" and could be construed as misinforming users. The court dismissed the suit in April 2018, stating the LG's ad was based on test results generated through objective means at reliable institutions and that no evidence was found that proved LG had intentionally made false or exaggerated claims. Qualtex In 2006, Dyson sued the parts manufacturer
