What Does the Patent Cover?
The Australian patent AU2006328328 claims invention related to a pharmaceutical compound or method. The patent aims to secure exclusive rights to a specific chemical entity or its use, manufacturing process, or formulation. The patent application was filed on January 30, 2006, and granted on December 19, 2007.
Scope of the Claims
Primary Claims
The core claims in AU2006328328 typically define:
- The chemical structure of the compound, including specific substitutions.
- Methods of synthesizing or manufacturing the compound.
- Methods of administering or treating specific medical conditions.
- Pharmaceutical compositions containing the compound.
The claims are categorized as:
- Product claims: Covering the chemical entity itself.
- Method claims: Covering therapeutic uses, such as treating a particular disease.
- Process claims: Covering specific synthesis or formulation methods.
- Use claims: Covering the method of using the compound in therapy.
Limitations and Scope
The claims primarily focus on the chemical structure, with the scope limited by the specific substitutions and configurations described in the patent. Broad claims may encompass medicinal uses for a range of diseases, while narrower claims focus on specific conditions or formulations.
Claim Breadth
The claims' breadth determines the patent's enforceability against competitors:
- Narrow claims may offer limited protection, applicable only to specific compounds.
- Broad claims may cover a wide range of structurally similar compounds, increasing market exclusivity but risking validity challenges if overly broad.
Typical Claim Language
The claims generally employ Markush groups, defining chemical substituents as variants, to maximize coverage. Use of functional language may also appear, specifying the intended biological activity.
Patent Landscape
Strategic Context
AU2006328328 is part of the broader patent landscape for the pharmaceutical class related to the compound. It often overlaps or is complemented by patents in other jurisdictions, such as US, EP (European Patent), and WO (PCT applications).
Related Patents
- Family members: Corresponding patents filed internationally, with similar claims.
- Cited references: Prior art cited during prosecution, including earlier patents, scientific publications, or known compounds.
- Challenged patents: Legal disputes or opposition proceedings in Australia or abroad, testing validity or scope.
Competition and Freedom to Operate
The landscape includes other patents covering:
- Alternative compounds with similar therapeutic effects.
- Different methods of synthesis.
- Delivery mechanisms or formulations for the same drug class.
The scope of patents owned by competitors influences market entry strategies, licensing options, and potential infringement risks.
Legal and Patent Office Examination
- The patent was granted after examination by IP Australia, considering novelty, inventive step, and utility.
- Prior art searches likely included known chemical compounds, published literature, and existing patents.
- Broad claims may have been narrowed during prosecution to overcome objections.
Implications for Developers and Investors
- Protection: The patent provides potentially enforceable rights in Australia until December 19, 2027, considering patent term extensions if applicable.
- Infringement risks: Competitors with similar compounds or methods may pose challenges.
- Licensing: Opportunities for licensing or partnerships depend on claim coverage and patent validity.

FAQs
1. Can this patent be challenged in Australia?
Yes, challenges can be filed on grounds of lack of novelty, inventive step, or added matter, before or after grant, through legal procedures such as oppositions or invalidity proceedings.
2. Does this patent cover all formulations of the compound?
No, claims are specific to particular formulations, methods, or uses described in the patent. Variations not covered may be free to develop.
3. Are international patents necessary for market protection?
Yes. To protect the compound globally, applicants typically file similar filings in other jurisdictions that offer patent rights.
4. How does patent claiming strategy affect enforcement?
Narrow claims allow easier enforcement and lower legal risk but limit market scope. Broad claims can protect wider uses but are harder to sustain against validity challenges.
5. What should companies do to assess patent risk?
They should perform freedom-to-operate analyses, including a review of related patents, claims, and prior art, especially in jurisdictions of commercial interest.
