Certain Transformers and Components Thereof; Inv. No. 337-TA-1517

The Commission instituted a Section 337 investigation based on Ayr Energy, Inc.’s complaint against Zetwerk Manufacturing Businesses Private Limited, Zetwerk Manufacturing USA Inc., KRYFS Power Components Ltd., and Unimacts Global, LLC. The accused products are certain transformer products and components, including power, inverter duty, and distribution transformers, as well as core steel, windings, tanks, and insulation systems. This investigation targets transformer supply-chain products used in electrical power infrastructure, including grid and renewable-energy applications. Because the requested relief includes a limited exclusion order and cease and desist orders, the case could affect U.S. imports and sales of key transformer components in a market already sensitive to capacity, sourcing, and energy-infrastructure demand. The investigation was instituted under Section 337(a)(1)(A), not based on patent infringement, but on alleged misappropriation of trade secrets, false advertising, unfair competition, trademark infringement, false designation of origin, and common law trademark infringement. The named complainant is Ayr Energy, Inc. of Mountain View, California; the named respondents include entities associated with Zetwerk, KRYFS Power Components, and Unimacts Global. The scope covers certain transformer products, including power transformers, inverter duty transformers, distribution transformers, and components such as core steel, windings, tanks, and insulation systems.
