The U.S. International Trade Commission (ITC) has issued a decision regarding Investigation No. 337-TA-1431. This investigation involved accusations against several companies for potentially violating Section 337 of the Tariff Act of 1930. The investigation centered on certain nanolaminate alloy coated metal parts and products containing these materials.

The investigation began on January 22, 2025. Modumetal, Inc. from Snohomish, Washington, filed the complaint. They claimed that certain companies were importing and selling metal parts that infringed on their patents. The concerned patents were U.S. Patent Nos. 10,253,419 and 11,242,613.

The companies accused were Parker Hannifin Corporation, Lu Chu Shin Yee Works Co., Ltd., Jiangsu DVP Hi Pressure Technology Co., Zhejiang Fitting Machinery Co., Ltd., and others from China, the Philippines, and India.

An administrative law judge (ALJ) initially found no violation of Section 337. This decision was reviewed by the ITC. Upon review, the ITC agreed with the ALJ’s findings. They found that there was no infringement of the patent claims.

The ITC also considered whether Modumetal had established a domestic industry based on the patents. They found that Modumetal did not meet the required technical standards. However, they noted that Modumetal might meet some economic requirements.

Modumetal had asked for a review of those findings, but the ITC affirmed with modified analysis that there was no violation. The ITC decided not to issue any exclusion orders against the companies involved.

The investigation has now been terminated. The ITC’s authority for these actions falls under Section 337 of the Tariff Act and their own rules. The decision was officially issued on July 16, 2026, with the announcement being filed on July 20, 2026.
