Shares of Digital Ally Inc. rocketed 62% toward a five-month high in premarket trade Friday, after the maker of video surveillance products announced a "significant" victory in its patent battle with Axon Enterprises Inc. , which was formerly Taser International.

The patent in question covers the automatic activation and coordination of multiple recording devices when a law enforcement vehicle's light bar is activated. "We look forward to restarting our patent infringement litigation in U.S. District Court against Axon, which had been stayed pending the Patent Office IPRs," said Digital's Chief Executive Stanton Ross.
