Company profile

Longse Technology Limited (also styled Longse / 长视科技; related Chinese entity Guangzhou Longse Technology Co., Ltd., now 长视科技股份有限公司) is a privately held Chinese video-surveillance manufacturer founded in 2006 and headquartered in Guangzhou, Guangdong. Chinese corporate filings describe it as a non-listed joint-stock company (股份有限公司(非上市)) with natural-person and investment-fund shareholders; it has no public ticker and no disclosed parent. Its own site claims roughly 600 employees worldwide and 200+ patents, while 2020 Chinese social-insurance filings for the main Guangzhou entity listed about 251 insured employees — the two figures are not directly comparable, and no reliable revenue figure is public.

Products / operations. Longse designs and manufactures security-video hardware: analog/HD and IP network cameras (value, full-color and "Pro" series), PTZ and dual-lens ultra-wide cameras, miniature and fisheye/specialty cameras, 4G/Wi-Fi solar-powered battery cameras, NVRs/XVRs/DVRs, switches and accessories, plus video-management software (VMS/VMSLite/iVMS320) and mobile apps. It sells through OEM/ODM customization and provides scenario-based surveillance solutions, exporting to 130+ countries per its website. It is an operating company, not a non-practicing entity.

Litigation posture. Across all tracked US cases Longse appears only as a defendant (0 as plaintiff, 2 as defendant), both in the Western District of Texas — the profile of an operating company defending against patent-assertion suits rather than itself asserting patents.

Notable cases. Both tracked matters are Cedar Lane Technologies Inc. v. Longse Technology Limited (W.D. Tex.), including civil action 6:22-cv-00655. Cedar Lane Technologies is a Canadian-based NPE widely characterized in Unified Patents, Stanford NPE Database and KIPO/Chinese trade analyses as an acquired-patent assertion entity; the Longse suits are part of a broad camera/imaging campaign (e.g., co-defendants Motorola Solutions, PixArt, Zhuhai RaySharp) asserting patents such as US 6,972,790. Those cases reportedly resolved by settlement. No merits conclusions are drawn here.
