Granted U.S. Patent Covers Technology for Maintaining Precise UAV Control When Communication Latency Impacts Operator Command

TAMPA, Fla., June 16, 2026 (GLOBE NEWSWIRE) -- JFB Construction Holdings (NASDAQ:JFB) announced that XTEND, a leader in software systems and artificial intelligence-powered robotics, has secured a U.S. patent protecting technology that enables unmanned aerial vehicles (UAVs) to maintain precise, reliable control when communications are degraded and latency impacts operator demand.

U.S. Patent No. 12,461,522 covers remote, accurate maneuvering of an unmanned aerial vehicle under communication latency, addressing one of the most fundamental challenges in autonomous and remotely operated systems. Disrupted communications and signal delay are increasingly the norm in modern contested environments, making the ability to sustain reliable UAV control under those conditions operationally critical. XTEND's patented technology allows operators to deploy autonomous systems that hold course and stay on target despite adverse conditions.

"Reliable autonomy has to hold up in every operational scenario, especially when communications are degraded and the environment becomes unpredictable," said Aviv Shapira, Co-Founder and CEO of XTEND. "Owning this intellectual property protects the capabilities that set our systems apart and makes them difficult for others to replicate. Now, as we scale across global defense and security markets, the technology behind that critical differentiation stays defensibly ours."

This patent complements XTEND's broader software and autonomy strategy. The company's XOS operating system enables operators to manage, supervise, and deploy autonomous robotic systems across air, ground, and maritime domains. By combining artificial intelligence, autonomy, and human decision-making, XOS allows operators to extend operational reach while maintaining meaningful oversight and control across autonomous assets operating in complex environments.

Securing this intellectual property is part of a sustained investment in the autonomy, navigation, and control technologies that XTEND continues to advance as demand for resilient unmanned systems grows worldwide.
