 a provisional application in the USA to register a patent that claims a method of use ATH434 and related compounds in non-neurologic diseases. The application was filed in the US as PCT/AU2024/051009 in September 2024. Responses to a subsequent search report will be addressed prior to March 2026.

On July 12, 2024, we filed a provisional application No. 63/670299 to register a patent that claims a dosing method for use by ATH434 for the treatment of neurological disease supported by clinical data. An amendment to the provisional application was filed in January 2025. PCT/AU2025/050750 was filed on July 11, 2025.

On July 31, 2024, we filed a provisional application with No. 2024902369 claiming 39 novel compounds potentially useful for the treatment of neurological and non-neurological diseases. This application will be allowed to lapse and will be refiled when additional data are available to support the claims.

On July 12, 2024, we filed a provisional application No. 2025900800 to register a patent that claims a novel salt form (HCl) and crystalline form of ATH434 potentially useful for the treatment of neurological diseases. The application was filed as PCT/AU2025/05074 July 10, 2025.
