(Nasdaq: QUCY), a Nasdaq-listed autonomous defense technology company assembling an AI-powered System-of-Systems platform for drone warfare, counter-UAS, and border security applications, today announced it has filed a non-provisional utility patent application with the United States Patent and Trademark Office (USPTO) for an Electromagnetic Pulse Shielding Composite Filament for Fused Deposition Modeling and Method of Manufacture Thereof. EMP Hardening as a Structural CapabilityThe patent application describes a multi-component composite thermoplastic filament formulated for use in standard fused deposition modeling (FDM) three-dimensional printers. The filament, composed of a PETG polymer matrix combined with aluminum flake, carbonyl iron powder, carbon black, and milled carbon fiber, produces 3D-printed drone enclosures that achieve broadband shielding effectiveness of 35 to 55 dB across the full frequency range of 10 kHz to 10 GHz, as measured per ASTM D4935. Unlike metallic Faraday enclosures or conductive gaskets that impose weight and manufacturing complexity penalties incompatible with modern UAV size, weight, and power constraints, the Company's filament is designed for use with commercially available desktop FDM printers, enabling on-demand production of EMP-hardened drone enclosures and electronics housings at the unit level. Strategic Significance: A Documented Gap in the Drone Defense EcosystemElectromagnetic pulse attacks represent one of the most consequential unsolved problems in autonomous drone warfare. A single EMP event -- whether generated by a high-altitude nuclear detonation, a non-nuclear electromagnetic device, or a high-power microwave weapon -- can simultaneously destroy the semiconductor components and flight control systems of an entire drone swarm. No publicly listed drone defense company, including platforms the Company monitors as market comparables, currently offers a fielded EMP-hardening solution at the drone enclosure level. Quantum Cyber believes this patent application establishes its first-mover position in EMP hardening...
