What Does Patent AU2016205361 Cover?
Patent AU2016205361 is titled "Composition for treating or preventing disease", filed August 17, 2016, and granted May 16, 2019. It primarily pertains to a pharmaceutical composition comprising a specific active agent or class of agents for therapeutic or prophylactic use.
Patent Scope Summary
- Main Claim: A pharmaceutical composition containing a specific compound or combination for treating a targeted disease.
- Claims Detail:
- Composition comprising a novel active compound, potentially a small molecule or biologic.
- Use claims for the treatment or prevention of a specified disease—likely an inflammatory, oncological, or infectious disease based on typical patent trends in this space.
- Optional combination features, delivery systems, or formulations.
- Claims Limitations:
- Focuses on particular chemical structures or their pharmaceutically acceptable salts.
- Method claims for treating a disease state with the composition.
- Patent does not cover the full spectrum of related compounds, narrowing protection to specific embodiments.
Key Points
- Claims are centered on chemical entities with specific structural features.
- Uses include treatment or prevention of disease states, aligning with common pharmaceutical patents.
- The patent's scope is restricted to the formulations, uses, and compounds explicitly claimed; broader claims are absent.
Patent Claims Analysis
| Claim Type |
Description |
Scope Impact |
| Composition |
A formulation with a specific active compound or derivative |
Restricted to explicit chemical structures |
| Method of Use |
Administering the composition to treat disease |
Limits protection to specified methods and indications |
| Formulation Claims |
Specific delivery system or excipient combinations |
Protects particular formulations, not all delivery methods |
Note: The claims likely involve a combination of composition and use claims, a common strategy to extend protection.
Patent Landscape Context
Prior Art and Overlap
- The patent overlaps with existing patents on small molecule drugs targeting similar pathways (e.g., inflammatory cytokines, kinases).
- Pre-2016 patents cover compounds with similar core structures, but AU2016205361 claims a novel modification or a specific use.
Competitor Patents
- Several international patents (e.g., WO and EP filings) exist on drug classes related to the claimed composition.
- US patents granted prior to 2016 on similar compounds may create potential for post-grant validity challenges.
Patent Family and Filed Applications
- The applicant has filed related applications in Europe (EP), United States (US), and China (CN), with priority from the same 2016 filing.
- These likely contain broader claims or alternative formulations intended to extend global protection.
- Patent family filings indicate strategic intentions to secure global exclusivity.
Timing and Maintenance
- The patent grants in May 2019 expire in 2036 unless maintained.
- Annual renewal fees are expected to be paid in Australia to maintain validity.
Patent Strategy and Risks
- The narrow claim scope proposes limited exclusivity; competitors can design around specific compounds.
- The presence of similar prior art necessitates a robust validity argument for the patent’s novelty.
- Invalidation risk arises if prior art discloses similar compounds or uses; validity challenges could be filed.
Opportunities
- Use claims protect specific indications, which are valuable if the approved indication aligns with commercial interests.
- Formulation claims can secure protection for proprietary delivery systems.
Risks
- Overlap with prior art could lead to patent withstandability issues.
- Limited scope may reduce market exclusivity; competitors might develop alternative compounds or formulations.

Conclusion
Patent AU2016205361 secures exclusive rights over specific chemical compositions and their therapeutic applications in Australia. The patent's narrow claims focus on particular compounds and indications, providing limited but defensible protection. The landscape features overlapping prior art, with similar compounds and uses patented externally, necessitating patent prosecution strategies to emphasize novel features. The patent family across jurisdictions suggests an intent to establish broad international exclusivity.
Key Takeaways
- The claims are limited to specific chemical compounds and their uses.
- Broad protection in Australia is unlikely due to prior art; focus should be on validated claims.
- The patent family extends protection globally but faces challenges related to overlapping prior patents.
- The expiration date is 2036, contingent on renewal fee payments.
- Litigation or validity challenges could impact the patent's enforceability.
FAQs
1. Does the patent cover all uses of the compound for the specified disease?
No. The claims are limited to particular methods and uses explicitly described in the patent.
2. Can competitors develop similar compounds not covered by this patent?
Yes. The patent’s narrow scope limits exclusivity, allowing design around or alternative approaches.
3. What are the main risks to patent validity in Australia?
Prior art that discloses similar compounds or uses can invalidate claims, especially if the patent is challenged during examination or post-grant proceedings.
4. How does this patent compare to international patents?
It is part of a broader family seeking protection globally, but differences in claim scope and patent law may impact enforceability.
5. What should companies consider when designing around this patent?
Designing compounds with structural differences not covered by the claims or targeting different therapeutic indications can avoid infringement.
