Company profile

Luozhi Trading Co., Ltd. (rendered "LuoZhi Trading Co., Ltd." in USITC filings) is a China-based trading company that the Commission identifies as located in Guangzhou/Guangdong, China. It appears to be a privately held Chinese-registered exporter with no public ticker, no identified parent or ultimate owner, and no corporate website or SEC/10-K disclosure. No reliable public source supports an employee count or revenue figure; Chinese customs-aggregator listings for similarly named entities show only small shipment volumes and should be treated cautiously because of name-match uncertainty.

The company was founded/registered at a date that could not be verified from public sources. It is best characterized as a trading/export business rather than a manufacturer. Its only verified product involvement in the case data is third-party (aftermarket) ink cartridges and components sold for import into the United States. Trade-database entries tied to the name include printing-ink and pigment HS codes, consistent with that sector, but no branded product line or company website could be confirmed. It is not an NPE or shell licensor.

Litigation posture: Luozhi appears in the tracked data only as a defendant — 0 cases as plaintiff, 1 as defendant. That is the classic profile of an import-side operating/trading company being attacked by a patent holder, not a patent assertion entity. (Section 337 is an ITC venue, not a district-court forum such as the Eastern District of Texas.)

Notable case: The sole tracked matter is Epson Portland Inc. et al. v. Dongguan Ocbestjet Digital Technology Co., Ltd. d/b/a Ocbestjet et al., USITC Inv. No. 337-TA-1452 ("Certain Ink Cartridges and Components Thereof II"). Epson Portland Inc., Epson America, Inc., and Seiko Epson Corporation filed the complaint on May 13, 2025, asserting US Patent Nos. 8,764,172; 9,370,934; 11,535,038; 12,240,248; and 12,240,249, and seeking a general or limited exclusion order plus cease-and-desist orders against roughly 20 respondents. Luozhi was found in default (initial determination No. 6, Sept. 15, 2025; Commission declined review Nov. 17, 2025). Public reporting also lists Luozhi among respondents in Epson's companion "Ink Cartridges I" complaint (337-TA-1451), which is not in our tracked list.
