Estimated reading time: 3–5 minutes

The U.S. International Trade Commission (USITC) made an important decision on September 21, 2026. They found a violation of Section 337 of the Tariff Act of 1930. This involves some boiler protection systems and their parts.

The systems in question are used for absorption refrigeration. They were found to infringe on claims 1, 4, 6, and 10 of U.S. Patent No. 8,056,360. This patent belongs to ARPC LLC and Paul N. Unmack from Butte, Montana.

A general exclusion order was issued. This order stops the import of the infringing boiler protection systems into the U.S. Cease and desist orders were also issued against companies that did not respond to the orders.

The investigation started on June 18, 2025. The complaint alleged that certain companies imported and sold these infringing products in the U.S.

These companies include Koofang, Bydorunce, RVGIVE, and more, mainly based in China.

Several companies were found in default for not responding. These are Koofang, RVGIVE, Little Bear Pocket, and VISVIC.

On May 21, 2026, the final decision supported the complainants. The commission confirmed the violation concerning the claims in the patent. The economic impact of these violations was considered and found significant.

Finally, a bond of 100% of the value of the infringing products is required during the President’s review period.

This decision highlights the importance of protecting U.S. patents from unfair import practices.
