Aqua Metals Secures First Patent for AquaRefining Equipment and Processes

Technology passes rigorous examination of novelty, utility and prior art

Tailwinds’ Take: Line ’em up and knock ’em down. The short stories are falling one by one here. Getting this patent is a very important event for the long term benefit of AQMS, not only in lead but a great step as they eventually look to move into recycling of other metals

ALAMEDA, Calif., June 01, 2017 — Aqua Metals, Inc. (AQMS), (“Aqua Metals” or the “Company”), which is commercializing a non-polluting electrochemical lead recycling technology called AquaRefining™, has secured its first patent; Korea Patent No. 10-1739414, “Devices and Method for Smelterless Recycling of Lead Acid Batteries.”

The Company made a strategic decision to choose the Korea Intellectual Property Office (KIPO) as the examining authority because of its well-known rigorous examination process. To that end, Australia, China and other key Asian territories tend to follow KIPO’s lead. Korea is also one of the world’s largest lead producers with a metals industry that uses large scale hydro-metallurgical processes.

“While our initial patent provides us with protection in Korea only, we believe this first patent sets a strong precedent that our technology is novel, of utility and an advancement over the prior art,” said Dr. Stephen Clarke, chairman and CEO of Aqua Metals. “We anticipate this will be the first of many patents to be issued in the coming months. More importantly, this is a landmark moment for our team – our technology has passed muster in one of the toughest patent jurisdictions in the world, which paves the way for success elsewhere. We are extremely proud of this achievement, and believe it validates the hard work and progress our team has put forth.”

The Company is pursuing a comprehensive and rigorous IP Strategy with more than 20 planned filings organized into several “families” covering “matter”, “devices” and “processes” in up to 20 territories.

About Aqua Metals
Aqua Metals, Inc. (AQMS) is reinventing lead recycling with its patented and patent-pending AquaRefining
TM technology. Unlike smelting, AquaRefining is a room temperature, water-based process that is fundamentally non-polluting. These modular systems allow the Company to vastly reduce environmental impact and scale lead acid recycling production capacity both by building its own AquaRefineries and licensing the AquaRefining technology to partners. This meets growing demand for lead to power new applications including stop/start automobile batteries which complement the vehicle’s main battery, Internet data centers, alternative energy applications including solar, wind, and grid scale storage. Aqua Metals is based in Alameda, California, and has built its first recycling facility in Nevada’s Tahoe Reno Industrial Complex. To learn more, please visit
