Lead battery recycler Aqua Metals was issued a Notice of Allowance by the United States Patent and Trademark Office for the first US patent for its AquaRefining technology on October 16.
A Notice of Allowance determines that the patent application meets all requirements to satisfy a patent application – ie description, design, drawings or blueprints.
After two more steps – submitting any drawing corrections and paying the fees – the patent can be issued.
The patent applicant has three months from the date of issue of the Notice of Allowance to file a statement of use or apply for a one-month extension. If the three months expire, the patent is not granted.
Aqua Metals has already had patents issued in Japan, Korea and Australia, and has licensed the technology to Johnson Controls.
