ITCJune 26, 2026·337-TA-1507·INVESTIGATION INSTITUTED

Certain Heavy Machinery and Components Thereof; Inv. No. 337-TA-1507

U.S. International Trade Commission

Holding

The ITC instituted Investigation No. 337-TA-1507 based on Caterpillar Inc.'s complaint alleging that Doosan Bobcat entities violate Section 337 through importation and sale of infringing heavy machinery and components. The accused products are telehandlers, excavators, loaders, and components thereof, asserted to infringe claims of four Caterpillar patents.

Why It Matters

This investigation targets major categories of construction and earthmoving equipment in a highly competitive heavy machinery market. If Caterpillar proves infringement, domestic industry, and importation, the ITC could issue exclusion and cease-and-desist orders affecting Doosan Bobcat's ability to import and sell accused machines and components in the United States.
