Standard Lithium Receives Notice of Allowance for Final U.S. Patent Covering DLE Process for Recovering Lithium From Brines

Successful Completion of USPTO Review Process for Company’s Lithium Extraction Patents

VANCOUVER, British Columbia, Dec. 29, 2022 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV: SLI) (NYSE American: SLI) (FRA: S5L), a leading near-commercial lithium company, is pleased to announce that the United States Patent and Trademark Office (“USPTO”) has issued a Notice of Allowance for Standard Lithium’s third U.S. patent application serial no. 16/895,783 titled “Process for Recovering Lithium from Brines”, This third U.S. patent application is in addition to Standard Lithium’s other two U.S. patent applications for which Notices of Allowance have been earlier issued by the USPTO (U.S. patent applications serial no.16/410,523 and serial no. 16/224/463, both also titled “Process for Recovering Lithium from Brines” see news release November 1, 2022). These three U.S. patent applications comprise a portion of Standard Lithium’s novel and proprietary technique for continuous Direct Lithium Extraction (DLE) from lithium brines.

A Notice of Allowance is issued by the USPTO after examination of a patent application and a determination that a patent should be granted from the application. Standard Lithium anticipates the issue of the formal registration of this third U.S. patent application in the coming months.

“We are pleased to have received the Notice of Allowance for the final U.S. patent application of the Company’s lithium extraction technology,” commented Dr. Andy Robinson, Standard Lithium’s President, and COO, adding, “We will continue to strengthen our IP portfolio but more importantly we are actively advancing our south Arkansas lithium projects and doing so by applying sustainable, scalable and fully-integrated modern processing technologies to unlock new U.S. commercial lithium production.”
