Defendant
1 case as defendant.
ZKTeco USA, LLC is the U.S. arm of ZKTeco Co., Ltd. (SZSE: 301330), a Shenzhen-listed biometric-security manufacturer founded in 2007 and listed in 2022. ZKTeco USA was established around 2009 and is headquartered in Alpharetta, Georgia (earlier listings show a Fairfield, New Jersey address). The parent reports roughly 3,500 employees worldwide, about 1,000 in R&D; third-party trackers put the U.S. subsidiary at roughly 45–65 employees and estimated annual revenue in the $7M–$11M range. These U.S. figures are third-party estimates, not audited disclosures.
Products and operations. ZKTeco USA sells physical security and workforce-management hardware: fingerprint, facial, palm and finger-vein readers; standalone biometric readers and access-control panels; turnstiles, walk-through metal detectors, X-ray baggage scanners and elevator controllers; video surveillance; visitor-management systems; and time-and-attendance terminals. Its main U.S. site includes a warehouse and a user-experience center. In 2025 it launched Cielo365, a cloud-based access-control software platform, and its products carry LenelS2 and OSDP certifications.
Patent-litigation posture. Operating company defending, not asserting. In the tracked data ZKTeco USA appears in exactly one case and only as a defendant (zero plaintiff suits) — the profile of a product company being targeted rather than a litigant monetizing patents.
Notable case. The sole tracked matter is Cedar Lane Technologies Inc. v. ZKTeco USA, LLC (D.N.J.). Cedar Lane is a Canadian-domiciled patent assertion entity that acquired its portfolio from Intellectual Ventures/AVInnov and files high-volume infringement complaints (Unified Patents and Stanford NPE litigation data both classify it as a non-practicing entity). Public docket records for the D.N.J. matter (No. 2:23-cv-01693) show a voluntary dismissal without prejudice in May 2023, before ZKTeco answered; the asserted patents concern host interfaces for imaging arrays (e.g., U.S. 6,972,790 and 8,537,242). The venue — District of New Jersey rather than the Eastern District of Texas — is consistent with Cedar Lane's broad, multi-district filing pattern.
