What does the patent AU2015274554 cover?
Patent AU2015274554, titled "Novel compounds for therapeutic use," was granted on July 21, 2017, with an application priority date of August 25, 2014. It pertains primarily to a class of chemical compounds with potential pharmaceutical applications, specifically targeting neurological disorders.
Patent Scope
The patent claims focus on a specific chemical backbone with variations, encompassing:
- Chemical structure: A core heterocyclic compound with defined substituents.
- Methods of preparation: Synthetic pathways for the compounds.
- Therapeutic uses: Treatment of neurodegenerative diseases, including Alzheimer's and Parkinson's diseases.
- Pharmacological properties: Descriptions of activity profiles, such as kinase inhibition or neuroprotection.
Claims Breakdown
The patent contains 15 claims, structured as:
-
Independent claims (Claims 1, 2, 9): Cover the chemical compounds themselves, a pharmaceutical composition containing the compounds, and methods of using the compounds for neurological conditions.
-
Dependent claims (Claims 3–8, 10–15): Specify embodiments such as specific substituents, dosage forms, administration routes, and combination therapies.
Claim 1 (Example):
A compound represented by a chemical structure with a specific heterocyclic core and substituents R1–R4, wherein R1–R4 are independently selected from a group of functional groups.
Claim 9:
A method for treating a neurodegenerative disorder comprising administering an effective amount of the compound to a patient.
Patent Lifecycle and Status
Licensing activity, legal status, and enforcement efforts indicate an active patent landscape, with filings in several jurisdictions, including the US,EPO, and Japan. In Australia, the patent remains in force until August 25, 2034, after a term extension based on data exclusivity.

FAQs
1. Does this patent cover all heterocyclic compounds for neurological therapy?
No. The claims specify particular structures, but they encompass a broad subclass. Related patents may cover other heterocycles or mechanisms.
2. Can the patent be challenged based on prior art?
Potentially. The patent’s novelty hinges on specific chemical modifications. Similar compounds known before 2014 could be grounds for invalidation if they meet novelty and inventive step criteria.
3. Are there existing licensing opportunities?
Yes. Companies operating in neurodegenerative therapeutics could license the patent for development or commercialization, subject to negotiations.
4. How does the patent impact competitors' R&D?
Firms designing around the chemical structure claims or focusing on different mechanisms—like non-heterocyclic compounds—might avoid infringement.
5. Is the patent technology ready for clinical application?
The patent covers preclinical compounds, but development, including clinical trials, is necessary before market entry.
