Standard Lithium Files Non-Provisional US & International
Patent Applications for Its Lithium Extraction Technology
Standard Lithium Ltd. (“Standard Lithium” or the
“Company”) (TSXV: SLL) (OTC-Nasdaq Intl. Designation: STLHF) (FRA:
S5L), announced that the Company has filed a patent application
with the U.S. Patent and Trademark Office covering the Company’s
novel process for the recovery of Lithium from brine. Concurrently,
an application was also filed under the Patent Cooperation Treaty
(PCT) extending Standard Lithium’s entitlement to seek patent
protection for this invention in member states to the PCT (which
includes all important industrialized markets). Both the U.S.
and PCT patent applications claim priority out of the Company’s
previously filed U.S. provisional application.
The U.S. and PCT patent applications cover technology the
Company and its Scientific Advisory Team have developed. As
previously reported, a lithium extraction Mini-Pilot Plant
utilizing the Company’s proprietary process has demonstrated that
lithium can be selectively extracted from raw brine (i.e. with no
pre-treatment other than pH adjustment); can be converted into a
concentrated and substantially purified (compared to the feed
brine) lithium chloride solution; that the lithium-loaded sorbent
material can be continuously regenerated and recycled to the
extraction stage; and that overall lithium extraction efficiencies
of over 90% can be achieved.
The PCT is an international patent law treaty, which provides a
unified procedure for fixing a window to preserve the Company’s
right to elect national or regional patent treatment in each of the
PCT member states. There are currently 152 member countries
adhering to the PCT; thus, enabling near-global patent coverage
through successful patent prosecution, including in the U.S.,
Japan, South Korea, Europe, Canada, Australia, New Zealand, China,
Brazil, Russia, India, and the countries subscribing to the
European Patent Office.
