Ocbestjet Printer Consumables (HK) Co., Ltd.

Ocbestjet Printer Consumables (HK) Co., Limited ("Ocbestjet") is a Hong Kong–incorporated private limited company (company no. 1487257), formed 30 July 2010. Per a 2021 credit report, its issued capital is HK$10,000, it is solely owned by Chinese national Xiong Yi, and it holds no operating office in Hong Kong, using a company-secretary address (registered office later moved to Kwun Tong, Kowloon). It is the Hong Kong affiliate of Dongguan Ocbestjet Digital Technology Co., Ltd. (Dongguan, Guangdong), the group's manufacturing arm; Ocbestjet's own site says the business was founded in 2005, while Chinese registry records date the Dongguan entity to April 2010. Ownership is private, with no public ticker. No revenue figures are verifiable; the Dongguan company's registry lists ~95 insured employees, while Ocbestjet's site claims ~200 staff and a 6,000 sq m workshop.

Operations. Ocbestjet is an operating manufacturer of third-party ("compatible") printer consumables, not an NPE. Product lines include refillable and remanufactured ink cartridges, bulk/refill inks (dye, pigment, sublimation, UV, eco-solvent, latex), continuous ink supply systems (CISS), chips, decoders, print heads, and wide-format cartridges, compatible with Epson, Canon, HP, Lexmark, Brother, Roland and Mimaki printers. It also offers OEM/ODM private-label production. Its site reports 40 production lines and roughly 1.8 million cartridges monthly output.

Litigation posture. The tracked case data show zero plaintiff cases and one defendant case: Ocbestjet is purely a defensive respondent. This is the profile of an operating company targeted in an infringement action, not a patent asserter.

Notable case. Epson Portland Inc. et al. v. Dongguan Ocbestjet Digital Technology Co., Ltd. d/b/a Ocbestjet et al., USITC Section 337 investigation 337-TA-1451 ("Certain Ink Cartridges and Components Thereof I"), complaint filed 13 May 2025 by Epson Portland, Epson America and Seiko Epson, instituted 12 June 2025, asserting several Epson ink-cartridge patents and seeking exclusion and cease-and-desist orders. The Commission found Ocbestjet HK and its Dongguan affiliate in default (Order No. 13, December 2025). External reporting also places both entities in the parallel investigation 337-TA-1452, and Epson previously identified an "Ocbestjet component" in an earlier ink-cartridge Section 337 matter.
