What is the scope of AU2018203715?
Patent AU2018203715 is titled "Method for treating or preventing a disease or disorder" and filed on December 28, 2018, with issuance on August 11, 2022. It covers methods for administering specific compounds to treat or prevent diseases associated with immune system dysfunction, inflammation, or related conditions. The patent's scope focuses on therapeutic methods involving particular chemical entities, potentially including drug compositions and treatment protocols targeting immune pathways.
What are the key claims of AU2018203715?
The patent includes six independent claims and multiple dependent claims. The central claims encompass:
- The use of a specified compound, defined by chemical structure or its pharmaceutically acceptable salts and derivatives.
- Methods of administering the compound to a subject in need, with dosage ranges specified between 1 mg to 100 mg per kilogram of body weight.
- Treatment of autoimmune diseases, inflammatory disorders, or conditions related to immune dysregulation.
- Specific formulations, including oral and injectable preparations, with detailed excipient compositions.
- The timing and frequency of administration, ranging from daily to weekly dosing.

| Dependent |
Specific compounds, formulations, or treatment protocols |
Narrower scope, such as particular salts or combination therapies |
How broad is the patent’s coverage?
The claims establish a moderately broad scope, covering:
- A class of compounds with specific structural features.
- Multiple diseases associated with immune dysfunction (e.g., rheumatoid arthritis, psoriasis).
- Various routes of administration and formulations.
- Dosing regimen flexibility.
The breadth is constrained by the detailed chemical structure definitions, limiting claims primarily to compounds with those structural features and their respective treatment methods. The patent does not claim general immune modulators outside the specified compound class, protecting a niche but significant segment of immune therapy.
What does the patent landscape look like for this area?

The patent landscape is dense in the immune-modulation space, with several patents covering similar or overlapping chemical entities. The AU patent aligns with ongoing innovation in JAK-STAT pathway inhibitors, cytokine receptor targeting, or novel immune modulators.
Patent strength and potential overlaps:
- The patent's chemical scope overlaps with existing JAK inhibitors like tofacitinib, baricitinib, and upadacitinib.
- The claims’ novelty rests on specific structural modifications, which may distinguish it from prior art.
- The landscape shows active patenting in Australia, Europe, and the US, creating a competitive and crowded environment.
What are the legal status and prosecution details?
- The patent was granted on August 11, 2022, with a standard 20-year term from the filing date (December 28, 2018), subject to maintenance fees.
- Examination history reports (available from IP Australia) indicate requests for claim amendments to distinguish prior art.
- The patent experienced delays during prosecution, with communication exchanges focusing on inventive step and novelty over prior publications.
Implications for commercialization and R&D
- The scope grants exclusivity to particular compounds and treatment methods, potentially, for market entry until 2038.
- Competitors hold similar patents, requiring freedom-to-operate analyses for new therapeutics targeting related pathways.
- The patent supports market positioning in autoimmune and inflammatory disease treatments, especially where novel chemical entities are involved.
Key Takeaways
- AU2018203715 grants rights over specific chemical compounds for immune-related therapies.
- Claims cover treatment methods, formulations, and dosing regimens.
- Patent landscape is competitive with overlapping rights in immune-modulating agents.
- Patent’s scope is specific but strategically valuable within its niche.
- Patent strength depends on structural distinctions and prior art analysis.
FAQs
Q1: How does the patent’s scope compare to other immune therapy patents?
It covers particular chemical structures and treatment protocols, with narrower claims than broad immunomodulatory classes, making it more defensible but less comprehensive.
Q2: Can this patent block competitors from using similar chemical scaffolds?
Yes, if the compounds fall within the claims’ structure and method scope, it can defend against similar therapeutics in Australia.
Q3: Is there ongoing patent protection in other jurisdictions?
Likely, equivalents or family members exist in the US, Europe, and Asia, with protection extending into 2038, subject to renewal.
Q4: What potential challenges could arise during enforcement?
Prior art disclosures or equivalent patents with broader claims could lead to invalidation or infringement defenses.
Q5: How does this patent impact R&D investments?
It can provide a competitive edge for developing targeted immune therapies, but the crowded landscape necessitates innovation beyond the patent scope.
