Investigation into extrusion‑coated magnet wire
If you import or sell extrusion-coated magnet wire, the U.S. International Trade Commission instituted an investigation on October 29, 2026, alleging infringement of U.S. Patent Nos. 8,847,075; 9,224,523; and 10,210,966. The accused products are described as "extrusion-coated magnet wire having an outer layer formed from an extruded thermoplastic resin." The complainants asked the Commission to issue a limited exclusion order and cease and desist orders, which could stop those products from being sold in the United States.
Specific companies named as respondents
Wellascent Electronic (Ganzhou) Co., Ltd. and Wellascent Technologies USA LLC are named as respondents in Investigation No. 337-TA-1527 and will be served with the complaint alleging violations of section 337. As named respondents, these entities face the investigation process and the potential for exclusion or cease and desist orders if infringement is found.
20‑day response requirement for respondents
Named respondents must submit responses under 19 CFR 210.13 and those responses will be considered only if received not later than 20 days after the date of service of the complaint and the notice of investigation. Extensions of time will not be granted unless good cause is shown, and failure to file a timely response may be deemed a waiver and can lead to an initial or final determination and the issuance of an exclusion order or a cease and desist order.
