USITC to start patent probe of Caterpillar

The US International Trade Commission said it will begin a patent infringement investigation of road milling equipment by Caterpillar and several subsidiaries after a complaint by Wirtgen America.

“The products at issue in the investigation are used to mill asphalt and concrete pavement to create an even base for the construction of a new surface,” said the USITC.

“The accused products include road milling machines, and components of a road milling machine such as: scrapers, auxiliary drives, height-adjustable lighting columns, milling drum uncoupling functionality and hydraulically stabilized chassis …

“The complaint alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain road milling machines and components thereof that infringe patents asserted by the complainant.

“The complainant requests that the USITC issue a limited exclusion order and cease and desist orders.”
