EcoGraf HFfree™ Australian Patent

The EcoGraf HFfree™ purification process was developed by EcoGraf in Australia in 2017 and has since been refined through extensive testing and analysis conducted in Australia, Europe and Asia. Patents and trademarks have been lodged by EcoGraf in all key battery markets to protect the IP associated with this process and on 8 November 2021 the Company reported that the International Preliminary Examining Authority acting under the Patent Co-operation Treaty had deemed all 25 of the EcoGraf patent claims as novel and inventive.

Based on this positive examination and finding, in December 2021 the Australian Government, through IP Australia, confirmed acceptance of the Company's patent application and published it in the Australian Journal of Patents as part of a 3-month exposure period during which oppositions can be raised to the proposed grant of a patent. Oppositions were lodged with IP Australia by two parties, who then provided their Statement of Grounds and Particulars in June 2022 and Evidence in Support in September 2022.

After reviewing the Evidence in Support, EcoGraf has filed its Evidence in Answer. The Opponents will be provided an opportunity to file any Evidence in Reply. Then it's expected that the Commissioner of Patents will appoint a delegate to consider the matter (which may include obtaining additional information and holding a hearing) and issue a decision. It is open to a party to appeal this decision to the Federal Court.

Protection of EcoGraf's significant investment in proprietary processing, innovation and new technology provides it with a competitive advantage and benefits Australia's position as a major supplier of critical minerals to global battery markets. The development of new Australian technologies supported by patents strongly aligns with the core principles of the Australian Government's Critical Minerals Strategy.
