Certain Extrusion-Coated Magnet Wire; Inv. No. 337-TA-3940 (Violation)

This supplemental complaint, filed by Essex Solutions Inc. and Essex Solutions USA LLC in Investigation 337-TA-3940 concerning certain extrusion-coated magnet wire, adds name-change language to paragraphs 30 and 36, replaces paragraph 59, and submits replacement and new exhibits. The new paragraph 59 alleges that an accused Wellascent PEEK wire product was displayed in a Schaeffler exhibit at the October 2025 Detroit Battery Show. The supplement bolsters the Complaint's allegations of importation and corporate identity, which are needed to support institution of the investigation. It does not describe the asserted patents or the relief sought in this document, though the filing relates to a Section 337 complaint. The record on importation now includes a declaration, Exhibit 28. Complainants are Essex Solutions Inc. and Essex Solutions USA LLC, represented by Merchant & Gould P.C. The supplement follows discussions with the Office of Unfair Import Investigations. Paragraphs 30 and 36 are supplemented with cross-references to the name change of Essex Furukawa Magnet Wire LLC to Essex Solutions Inc., citing Ex. 7. Paragraph 59 is replaced to allege that an accused Wellascent PEEK wire product was seen as a component in a Schaeffler product at the Detroit Battery Show in October 2025 and, on information and belief, was manufactured abroad and imported. New Exhibit 28, the October 8, 2026 Declaration of Lindsay A. Hartman, is added, along with replacement public versions of Exhibits 11 and 24 and replacement Exhibits 15 and 16.
