  • Quantum Cyber said it has filed a patent for its drone system in the U.S.

  • The company switched its focus from pharmaceuticals to defense earlier this year.

Shares of Quantum Cyber N.V. (QUCY) soared on Thursday after the company filed a new patent with the United States Patent and Trademark Office for its drone system, marking its fourth patent of the week as it anticipates a strong uptick in demand for its defensive solutions.

At the time of writing, QUCY stock was up more than 20% in premarket trading.

The latest patent comes on top of three other intellectual property filings made during the week for a remote-controlled, land-and-water-compatible vehicle, a naval mine-neutralizing solution, and a 3D-printing filament material for use in drones and other defense electronics.

Quantum Computing To Be The Navigation Backbone

Quantum Cyber, which made a complete U-turn from pharmaceuticals to defense earlier this year, said the company is building “an autonomous defense platform where quantum computing is not a concept, it is the navigation backbone of an entire unmanned vehicle fleet operating in the most contested environments on earth.”

These developments come amid the ongoing geopolitical crisis in the Middle East, with the U.S. continuing to bolster its attack capabilities using unmanned systems and countermeasures against cheaply produced Iranian drones.

Given the soaring demand for defense, especially for drones, the company also established a dedicated drone subsidiary, “Quantum Drones Corporation,” during the week to specifically cater to the U.S. government’s requirements for the war in the Strait of Hormuz.
