Vancouver-based Standard Lithium (TSXV: SLI) (NYSE American: SLI) (FRA: S5L) has made substantial progress with two patent applications on so-called novel and proprietary techniques for continuous direct lithium extraction (DLE) from lithium brines.
On Tuesday, the company announced that it had received notices of allowance from the United States Patent and Trademark Office (USPTO) for the two applications entitled: Process for Recovering Lithium from Brines.
Notices of allowance are issued when the USPTO is satisfied with a patent application and the company anticipates formal registration of both patents in the month to come.

“The successful Notice of Allowance from the USPTO provides continued affirmation of the Company’s lithium extraction technology and allows Standard Lithium to continue advancing its first commercial lithium extraction project with even greater certainty of intellectual property rights,” said Andy Robinson, president of the company.
Standard Lithium describes itself as an innovative company moving rapidly towards commercialization. Its flagship project is located in Arkansas where the company is currently designing its first commercial lithium project. That project is intended to be built on 150,000 acres of pre-existing pre-authorized brine operations.
The company says it is also currently seeking to develop over 30,000 acres of separate brine leases in southwest Arkansas — known as the South West Arkansas Lithium Project — and about 45,000 acres of mineral leases in California’s section of the Mojave Desert.
