Products / operations. Kum Oh is an operating company, not an NPE. It designs and manufactures electronic article surveillance and display-security hardware sold B2B to retailers and display-fixture integrators: anti-theft display stands and grips for smartphones and tablets, sensor-based alarm modules and anti-theft connectors that detect device removal, cable retraction/recoiler assemblies for display tables, camera anti-theft devices, plus related accessories such as wireless chargers, headphone charging stands and stylus holders. USPTO/FCC records list US and Korean patents in the company's name covering these mechanisms (e.g., U.S. 9,659,471 anti-theft apparatus for mobile device; U.S. 10,390,121 headphone charging stand; D798,875 connector). The company states it exports to customers in roughly 120 countries.
Patent-litigation posture. Purely defensive. In the tracked data Kum Oh appears in exactly one case and only as a defendant (0 as plaintiff), consistent with an operating company attacked over its products rather than an assertor. The suit, InVue Security Products Inc. v. Kum Oh Electronics Co., Ltd. (3:13-cv-00465, W.D.N.C., filed Aug. 14, 2013), was a direct competitor dispute — InVue, a Charlotte, N.C.-based retail security supplier, accused Kum Oh's M-1000/M-5000 series alarm systems of infringing U.S. 7,737,843 ("Programmable Alarm Module and System for Protecting Merchandise"). Venue was the plaintiff's home district, not a notably plaintiff-friendly patent venue such as E.D. Tex.
Case context. Kum Oh petitioned for inter partes review of the '843 patent (IPR2014-00457, filed Feb. 25, 2014); the district court denied Kum Oh's motion to stay pending IPR on April 3, 2014, and the case terminated July 25, 2014. No subsequent US litigation involving the company appears in the tracked data.
