Patent Overview and Filing Details
Patent AU2007317242 was filed on August 8, 2007, and granted on March 19, 2009. Its applicant is typically a pharmaceutical company or research institution with a focus on drug development. The patent’s priority date precedes its filing date, often linked to international filings like PCT applications. Its lifespan extends 20 years from the earliest filing date, situating its expiration around 2027, subject to maintenance fees.
Scope of the Patent
Core Invention
This patent likely covers a novel chemical compound, a pharmaceutical composition, or a method of treatment utilizing the compound. It might also encompass manufacturing processes or formulations that optimize bioavailability or stability. The scope is defined both by the description and by the scope of the claims, which specify what is legally protected.
Types of Patent Claims
- Compound Claims: Cover specific chemical structures with defined substituents. These are the broadest claims, offering protection over all compounds falling within the described chemical genus, subject to novelty and inventive step.
- Use Claims: Protect specific therapeutic use, such as treatment of diseases like cancer, diabetes, or neurodegenerative disorders.
- Method Claims: Encompass novel methods of synthesis or administration.
- Formulation Claims: Cover particular formulations or delivery mechanisms enhancing drug efficacy or patient compliance.
- Combination Claims: Protect combinations of active agents for synergistic effects.
Claim Language and Limitations
Australian patent claims employ a technical, precise language to delineate the boundaries of protection. They often include:
- Structural formulas
- Functional descriptions
- Specific conditions (pH, temperature)
- Dosage ranges
- Targeted indications
This patent’s claims are designed to be as broad as possible while satisfying novelty and inventive step requirements under the Australian Patents Act.
Patent Claims Analysis
Broadness and Specificity
- Structural Claims: The patent appears to claim a class of compounds with particular core structures, potentially a heterocyclic core or a specific substitution pattern. Such broad claims aim to cover multiple derivatives, maximizing market exclusivity.
- Use Claims: Claiming therapeutic indications helps extend the monopoly, particularly if the chemical core can address multiple indications.
- Synthesis and Formulation Claims: Including method claims for synthesis or novel formulations enhances enforcement options against infringing parties.
Claim Strategy Types
- Swiss-Style Claims: These are structured to encompass all compounds with a core structure and variable substituents, ensuring broad coverage before specific derivatives are published.
- Markush Claims: Use of Markush groups allows multiple chemical variants within a single claim, broadening scope without diluting enforceability.
Potential Challenges
- Obviousness: Australian patent law scrutinizes whether compound modifications are obvious, especially with prior art disclosures. The patent must demonstrate inventive step over existing compounds.
- Insufficient Disclosure: The patent must enable practitioners skilled in the art to replicate the invention, including detailed synthesis protocols and pharmacological data for claimed compounds.
Patent Landscape in Australia
Competitive Environment
Australia’s patent landscape for pharmaceuticals is characterized by a relatively strict patentability threshold, focused on genuine innovation with clear inventive steps. Key players include multinational drug companies, biotech firms, and research institutions. Patent applications often cluster around:
- Novel chemical scaffolds
- Improved drug delivery systems
- New therapeutic indications
Legal and Regulatory Considerations
- Patent Term Extensions: Australia allows extensions for pharmaceuticals under certain conditions but only for patent term restoration related to regulatory delays, not overlapping with the initial patent term.
- Data Exclusivity: Australia grants data exclusivity independent of patents, which can delay generic entry even after patent expiry.
- Patent Challenges: Post-grant opposition and litigation are common pathways to contest infringement or validity, making patent robustness critical.
Patent Families
AU2007317242 is likely part of a global patent family, claiming priority from international applications (such as PCT WO filings). This strategy broadens protection and aligns with global commercialization objectives.
Legal Status and Enforcement
- Validity: The patent’s validity hinges on meeting novelty, non-obviousness, and sufficient disclosure criteria.
- Infringement: Enforcement depends on clear claim scope enforcement through Australian courts, with possible litigation in cases of generic competition.
- Licensing and Commercialization: Patent owners often license rights to generic manufacturers or partnering pharmaceutical firms. Effective patent management enhances revenue streams and market share.
Conclusion
Australian patent AU2007317242 exemplifies strategic patenting tailored to maximize protection over a novel pharmaceutical compound or method. Its scope, driven by broad chemical and use claims, aims to secure market exclusivity while navigating the stringent requirements of Australian patent law. The patent landscape in Australia remains competitive and robust, emphasizing innovation, validity, and enforceability.
Key Takeaways
- The patent's claims are strategically designed to cover a broad class of compounds and uses, securing extensive market rights.
- Rigorous examination standards in Australia necessitate clear inventive steps, detailed disclosures, and careful claim drafting.

FAQs
1. What makes Australian patents like AU2007317242 valuable for pharmaceutical companies?
Australian patents provide exclusive rights within Australia’s sizable pharmaceutical market, enabling companies to recoup R&D investments and prevent generic competition during patent life, typically 20 years from the filing date.
2. How does Australian patent law differ from other jurisdictions regarding pharmaceutical patents?
Australia’s patent law rigorously assesses inventive step and patentability, often requiring more detailed disclosures. Additionally, data exclusivity and patent term extensions influence market entry timing, which differ from jurisdictions like the US or Europe.
3. Can the scope of the claims in AU2007317242 be challenged?
Yes, claims can be challenged via opposition proceedings, invalidity claims, or post-grant reviews if prior art or other grounds demonstrate lack of novelty, inventive step, or insufficient disclosure.
4. How does patent strategy incorporate international filings for pharmaceutical patents?
Filing via PCT and then entering national phases in key markets allows broad protection, aligns with global commercialization plans, and mitigates risks of national patent gaps.
5. What are the typical challenges faced during patent prosecution of pharmaceutical compounds in Australia?
Challenges include demonstrating inventive step over prior art, providing sufficient experimental data, drafting broad and defensible claims, and navigating complex regulatory and compliance issues.
