The complaint, as supplemented, alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain vertical power delivery systems, components thereof, and computing systems containing the same that infringe certain claims of the patent asserted by the complainant. The complainant requests that the USITC issue a limited exclusion order and cease and desist orders.

The ALJ will make an initial determination as to whether there is a violation of section 337; that initial determination is subject to review by the USITC.
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.
