In October 2024, DuPont filed a complaint with the United States International Trade Commission alleging that products made by the Chinese materials company Kingwills infringed intellectual-property rights associated with DuPont’s Tyvek brand and flash-spun nonwoven materials. Kingwills, founded in 2014 by Chen Boyi—also known as Eric Chen—had developed its competing Hypak material, called Kunlun in China, and placed a 3,000-ton flash-spun metamaterial production line into operation in August 2022. The dispute therefore centered not on a conventional fashion collection but on the industrial material technology used in protective apparel, packaging, and other technical products. DuPont sought exclusion of allegedly infringing Kingwills imports under Section 337 of the U.S. Tariff Act, a powerful trade remedy that can block goods at the American border. The USITC investigation began on November 21, 2024, but by November 25 the commission had made no determination on the merits. The documented story is consequently an active intellectual-property confrontation—not a proven finding that Kingwills copied DuPont—and its ultimate legal and commercial consequences remained unresolved in the source text.
