IP Spotlight - December 2025

As Australian patent attorney’s working closely with innovators in the critical minerals sector, we see firsthand how intellectual property (IP) is becoming the cornerstone of competitive advantage in this rapidly evolving field. Australia is uniquely positioned to lead in the global critical minerals landscape. But this leadership won’t be secured by geology alone, it requires strategic innovation, well protected IP, and a clear understanding of the challenges and opportunities ahead. Critical minerals are essential to the energy transition and to modern technologies. With significant deposits of lithium, nickel, rare earth elements, and copper, along with established mining expertise, Australia already plays an important role in global supply chains. Under the Net Zero scenario, this role is expected to grow. AUSTRALIA’S ROLE IN THE CRITICAL MINERALS SECTOR A significant technical bottleneck in the critical minerals sector lies in refining and processing capacity, which is heavily concentrated in a few countries – particularly China. China processes around 70% of global graphite and 90% of rare earth elements. These processing bottlenecks remain even with diversified raw material sources. For example, while Australia mines 55% of lithium globally, China refines 65% into battery-grade material. This creates serious supply chain vulnerabilities, as shown in 2023 when China banned antimony exports to the U.S. The Australian Government’s Critical Minerals Strategy 2023–2030 outlines a plan to expand downstream processing and strengthen supply chain resilience. But doing so means solving complex technical challenges, from advanced separation techniques to sustainable refining processes. REFINING BOTTLENECKS: A TECHNICAL AND STRATEGIC IP CHALLENGE

lithium recovery and processing Here’s where IP becomes indispensable. Patents and trade secrets can be used to protect the technologies that underpin new refining processes, separation techniques, and recycling methods. For companies, a well-structured IP strategy can protect proprietary processing technologies, create licensing opportunities, increase valuation, block competitors, and reduce infringement risks. At the national level, stronger IP control will support domestic ownership of critical technologies, reduce reliance on foreign technologies, and strengthen Australia’s position in global supply chains. Since 2010, there has been a steady increase in international patent filings relating to critical minerals technologies.
