Dongguan Ocbestjet Digital Technology Co., Ltd. d/b/a Ocbestjet

Company overview. Dongguan Ocbestjet Digital Technology Co., Ltd. (also stylized OcBestjet/Ocbestjet; Chinese name 东莞市奥彩数码科技有限公司) is a privately held Chinese printing-consumables manufacturer based in Dongguan, Guangdong. Chinese business-registry sources (Baidu Baike, Tianyancha) record incorporation on 29 April 2010 as Dongguan Aocai Printing Consumables Co., Ltd., renamed in 2017, with registered capital raised to RMB 80 million in September 2024. Company marketing pages give conflicting founding years (2005, 2009, 2010, 2012). Registry data list 95 insured employees (2024) and "small" enterprise size; the company's own site claims about 200 employees and a 6,000 m² factory. No public ticker; shares are held by domestic Chinese entities, with no disclosed parent.

Products / operations. It develops and manufactures aftermarket ("compatible") inkjet consumables and related equipment: refill inks (UV, soft-UV, DTG, DTF), compatible ink cartridges, continuous ink supply systems (CISS), chips and decoders, and DTF/flatbed curing equipment. Products are marketed as compatible with Epson, Canon, HP, Lexmark, Brother and Riso printers and sold under its own OCB/OCBestjet brands, plus OEM/ODM, largely for export. It is an operating manufacturer, not a non-practicing entity.

Patent-litigation posture. In the tracked data Ocbestjet appears once, as a defendant, with zero plaintiff-side cases — the profile of an operating company being targeted rather than a patent assertion entity. Its sole tracked appearance is an international-trade action rather than a district-court NPE suit.

Notable case. Epson Portland Inc., Epson America, Inc. and Seiko Epson Corp. v. Dongguan Ocbestjet Digital Technology Co., Ltd. d/b/a Ocbestjet et al., filed at the U.S. ITC on 13 May 2025 and instituted 12 June 2025 as Inv. No. 337-TA-1451 ("Certain Ink Cartridges and Components Thereof I"), with a parallel investigation (337-TA-1452) naming the same respondents; Epson asserts ink-cartridge patents and seeks exclusion and cease-and-desist orders. The complaint itself notes a May 2023 U.S. district-court permanent injunction against Dongguan Ocbestjet and affiliate Ocbestjet Printer Consumables (HK) Co., Ltd., and RTM World reports a similarly named Dongguan OcBestjet entity defaulted in Epson's earlier 337-TA-946 probe, which produced a 2016 general exclusion order on ink cartridges.
