Critical Infrastructure Technologies Ltd. (CSE: CTTT) (OTC: CITLF) (FRA: X9V) has announced that its United States patent application titled “A Mobile Radio Station” has been formally granted as U.S. Patent No. US 12,555,886. The patent, registered in the name of Critical Infrastructure Technologies Pty Ltd, covers the core technology underlying the Company’s Nexus platform architecture.
The U.S. patent grant is a significant milestone in CiTech’s global intellectual property strategy, securing protection in one of the world’s largest defence, telecommunications, and homeland security markets. The patented invention relates to CiTech’s deployable, autonomous mobile radio station system—an integrated, containerised communications platform designed for rapid establishment of secure connectivity in remote, disaster-affected, and high-threat environments.
The system integrates a transportable ISO container-based communications hub, a hydraulically deployed rigid scissor-lift mast, hybrid energy systems incorporating battery storage and renewable inputs, automated deployment functionality, and a climate-controlled, mission-ready communications architecture.
The United States represents a key strategic market for CiTech across defence, emergency response, border security, energy, mining, and aerospace sectors. The grant of the U.S. patent strengthens CiTech’s ability to protect its rigid mast and autonomous deployment technology, engage with U.S. defence and federal agencies, expand licensing and partnership opportunities, and secure long-term commercial advantage in mission-critical communications. The patent further enhances CiTech’s competitive positioning as it continues expanding its international footprint across North America, Europe, and allied markets.
CiTech’s invention defines a deployable, autonomous mobile radio station designed for rapid establishment of secure communications in remote or high-threat environments. The system overcomes the limitations of conventional mobile LTE and radio infrastructure by integrating transportability, energy autonomy, and intelligent automation. The patented design substantially expands CiTech’s Total Addressable Market, extending beyond traditional telecommunications infrastructure into defence, disaster response, remote industrial operations, mining, and emerging aerospace and satellite applications.
CiTech filed patent applications for “A Mobile Radio Station” in Australia, Canada, China, Europe, India, Japan, Republic of Korea, South Africa, Thailand, Vietnam and the United States. Along with the United States, South Africa have granted a patent. All other jurisdictions are either filed, under or awaiting examination. This extensive global IP coverage ensures broad protection of CiTech’s Nexus 20 technology across major defence and communications markets.
CiTech’s Nexus 20 platform delivers a fully self-contained, air-liftable communications hub capable of autonomous field operation, ideal for rapid network establishment in defence operations, disaster recovery, and remote mission support. A key differentiator of CiTech’s design is its super-rigid, precision-engineered mast, which maintains complete stability even under extreme wind conditions. Unlike competitor systems that suffer vibration and movement during operation, CiTech’s mast design ensures consistent, uninterrupted signal delivery—a critical requirement for mission-critical defence and communications environments. Its energy independence, automation, and structural integrity significantly reduce personnel exposure and logistics, enhancing reliability and operational readiness in demanding field conditions.
The system’s modular and AI-enabled architecture also positions CiTech for next-generation applications, including rapid-deploy satellite ground stations and mobile telemetry for aerospace and UAS test ranges, counter-UAS and electronic perimeter defence, areas of growing focus in NATO and European defence programs, and critical infrastructure protection and smart city security, enabling mobile monitoring for ports, airports, and large-scale civic events.
Brenton Scott, Chief Executive Officer of CiTech, commented: “Securing our United States patent grant is a major milestone for CiTech. The U.S. market is central to global defence and advanced communications innovation, and this patent strengthens our ability to commercialise the Nexus platform internationally. Protecting our intellectual property in the United States reinforces our long-term strategy of building sovereign, autonomous communications capability for allied nations.”
