The U.S. International Trade Commission (USITC) has voted to institute an investigation of certain polycrystalline diamond compacts and articles containing same.  The products at issue in the investigation are described in the Commission’s notice of investigation.

The investigation is based on a complaint filed by US Synthetic Corporation of Orem, UT, on November 23, 2020.  The complaint alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain polycrystalline diamond compacts and articles containing same that infringe patents asserted by the complainant.  The complainant requests that the USITC issue a limited exclusion order and cease and desist orders.

The USITC will make a final determination in the investigation at the earliest practicable time.  Within 45 days after institution of the investigation, the USITC will set a target date for completing the investigation.  USITC remedial orders in section 337 cases are effective when issued and become final 60 days after issuance unless disapproved for policy reasons by the U.S. Trade Representative within that 60-day period.
