Aether Catalyst Solutions, Inc. (CSE: ATHR) announced on September 30, 2025 that it has filed a national stage patent application for a novel base‑metal catalyst designed to replace platinum group metals in automotive emission converters. The filing follows an earlier Patent Cooperation Treaty (PCT) application and secures intellectual‑property rights in Canada, the United States, Europe, India, Japan, and South Korea.
The new catalyst technology relies on cost‑effective mixed metal oxides, eliminating the need for expensive platinum group metals while maintaining or improving catalytic activity. Aether’s focus on rapid screening of new materials aims to enhance end‑of‑life conversion levels after accelerated aging, positioning the company to address both current and emerging commercialization opportunities in light‑duty vehicles, commercial fleets, hybrid platforms, and small off‑road engines.
By securing this patent, Aether Catalyst Solutions strengthens its competitive position in the automotive emissions market, potentially reducing production costs for vehicle manufacturers and opening new revenue streams as the technology moves toward commercialization. The filing marks a significant operational milestone that could have long‑term financial and strategic benefits for the company and its shareholders.
