Shen Zhen Sailing Technology Limited d/b/a Triple-Color

Shen Zhen Sailing Technology Limited (d/b/a "Triple-Color")
Chinese name: 深圳市赛凌科技有限公司. The company is based in Shenzhen, Guangdong, China — the Epson complaint gives its address as Unit 807, Bairuida Building, Bantian Street, Longgang District, Shenzhen 518111. It appears to be a privately held Chinese entity; no public listing, parent company, employee count, or revenue figure could be verified from available sources, so none is given here.

Products / operations
Sailing markets third-party printer consumables, specifically aftermarket/replacement ink cartridges and cartridge components compatible with Epson printers, sold under the "Triple-Color" brand. The Epson complaint describes it as a seller of accused ink cartridge products through an eBay storefront, and alleges (on information and belief) that Sailing is affiliated with respondent Mountain Peak, Inc. d/b/a Toner Kingdom, which fulfilled some of its eBay orders. This is an operating commercial seller, not a non-practicing entity or shell licensor — it holds no asserted portfolio and does not appear as a patent plaintiff.

Litigation posture
Tracked data show 1 case, with Sailing as defendant and 0 as plaintiff — consistent with an operating company targeted in a supplier-side enforcement campaign. The single tracked matter is an ITC Section 337 action, not a district court suit, so there is no plaintiff-friendly venue cluster (e.g., E.D. Tex.) to note.

Notable case
Epson Portland Inc. et al. v. Dongguan Ocbestjet Digital Technology Co., Ltd. d/b/a Ocbestjet et al. (U.S. International Trade Commission, filed May 13, 2025) — Epson asserted U.S. Patent Nos. 8,540,347, 9,061,508, 11,535,037, 11,820,150 and 12,246,539 and sought a general or limited exclusion order plus cease-and-desist orders. Sailing was terminated from the investigation (Inv. No. 337-TA-1451) by withdrawal of the complaint, per Order No. 12 (Dec. 16, 2025), unreviewed Jan. 7, 2026. A parallel Epson investigation covered related cartridges and a separate patent set.
