Quanta Computer Inc. (廣達電腦; TWSE: 2382) is a Taiwanese contract manufacturer founded in 1988 and headquartered in Taoyuan City, Taiwan. It is publicly listed on the Taiwan Stock Exchange; its 1999 listing and current market data are reported by FT Markets and PitchBook. Size figures vary by source: FT/PitchBook report roughly 121,900 employees and trailing-12-month revenue of about NT$2.45 trillion, while Fortune's 2026 Global 500 ranked it at US$68.2 billion in 2025 revenue. Third-party headcount estimates range widely (roughly 57,000 to 122,000), so the precise figure should be treated as approximate.
Operations. Quanta is one of the world's largest original design manufacturers (ODMs). Historically the leading notebook PC manufacturer for global brands, it now derives most revenue from its cloud/enterprise segment (QCT): AI and general-purpose servers, rack-level data-center infrastructure, storage and network switches. It also makes notebook PCs, automotive cameras and ADAS modules, IoT and smart-manufacturing systems, telco infrastructure, smart healthcare devices, and AR/VR displays. It operates manufacturing across Taiwan, mainland China, Thailand, the U.S., and Europe.
Litigation posture. This is an operating company, not a patent assertion entity. The tracked data show 0 cases as plaintiff and 1 as defendant: Ricoh Company, Ltd. v. Quanta Computer Inc. et al., filed August 24, 2006 in the Western District of Wisconsin — a defendant-side, competitor patent suit rather than an NPE action, and not filed in a notoriously plaintiff-friendly venue such as the Eastern District of Texas.
Case context. Ricoh asserted optical disc drive patents (including U.S. Patents 5,063,552, 6,172,955, 6,631,109 and 6,661,755) against Quanta and its optical-storage affiliate Quanta Storage Inc. A November 24, 2009 judgment awarded Ricoh US$14.5 million against Quanta Storage. The Federal Circuit (2009) vacated and remanded the district court's summary judgment of no contributory infringement, holding that a separable component with no substantial noninfringing use can support liability even when embedded in a larger product. In April 2010 the district court denied a permanent injunction, noting Ricoh had ceased making disc drives and had broadly licensed the patents. Separately, Quanta is known for Quanta Computer, Inc. v. LG Electronics, Inc. (2008), a Supreme Court patent-exhaustion decision; that case is not part of the tracked case list above.
