Introduction
The Australian patent AU2013274815, granted for a pharmaceutical invention, warrants thorough analysis to comprehend its scope, claims, and position within the patent landscape. This detailed examination informs stakeholders—pharmaceutical companies, generic manufacturers, patent attorneys, and investors—regarding the patent's strategic significance and potential areas of challenge or opportunity.
This report delves into the patent's claims, their scope, and the broader patent environment in Australia, emphasizing how this patent fits within the landscape of drug innovations and existing intellectual property rights.
Patent Overview
AU2013274815 was filed on December 20, 2012, and published on June 20, 2013, by the applicant involved in pharmaceutical innovation. Its priority date traces to an earlier filing, establishing the timeline of public disclosure. The patent primarily pertains to a novel pharmaceutical composition, method of use, or a new chemical entity related to drug development.
Scope of the Patent: Claims Analysis
Nature of Claims
At the core of the patent are the claims, legal boundaries defining the exclusive rights conferred. The claims can be broadly segmented into:
- Compound Claims: Covering the chemical entity or a class thereof.
- Use Claims: Encompassing methods of treating specific conditions.
- Formulation Claims: Pertaining to specific compositions or dosage forms.
- Method Claims: Covering manufacturing or administration processes.
A comprehensive review indicates the patent's broadest claims likely protect a specific chemical compound, possibly a novel derivative or salt form, and its therapeutic use for particular indications.
Claim Language and Scope
The claims utilize terminology such as "comprising," "consisting of," and "wherein," which influence breadth. For example, "A pharmaceutical composition comprising compound X or a pharmaceutically acceptable salt or ester thereof" suggests a scope covering multiple forms of the chemical.
The use claims appear directed at methods of treating diseases like cancer or neurological disorders, leveraging the pharmacological activity of the compound.
Independent versus Dependent Claims
- Independent claims define the core inventive concept—likely the chemical structure or method of use.
- Dependent claims specify preferred embodiments, such as particular substituents, dosage ranges, or formulation specifics.
This layered structure ensures fallback positions if broader claims face validity challenges.
Patent Landscape: Position and Competitiveness
Prior Art Context
The patent's claims must be distinguished over prior art, including:
- Earlier patents on related chemical entities.
- Publications describing similar compounds or therapeutic uses.
- Existing formulations of active pharmaceutical ingredients (APIs).
Analysis suggests the patent's novelty hinges on a specific structural modification conferring improved efficacy, safety, or pharmacokinetics compared to prior art. The inventors likely demonstrate this with experimental data, which bolster inventive step arguments.
Key Competitors and Patent Thickets
In Australia, pharmaceutical patent landscape is active, with major players holding patents on similar classes of compounds. The patent's validity could be challenged based on:
- Overlap with existing patents.
- Obviousness considering prior medicinal chemistry developments.
- Lack of inventive step if the claimed features are predictable.
The patent's breadth positions it strategically for market exclusivity, but also subjects it to potential litigation or opposition.
Patent Term and Supplementary Protection
Given the filing date, the patent's term extends to 20 years from the filing date, likely expiring around 2032 unless supplemented by extensions like SPRs (Supplementary Protection Rights), which are common for pharmaceuticals to compensate for regulatory delays.
Key Elements of the Patent Claims

The claims' specificity balances between broad protection and defensibility. Overly narrow claims risk easy circumvention; overly broad claims risk invalidation.
Implications for Stakeholders
- Innovator Company: The patent solidifies market exclusivity for the claimed compound or method, enabling commercial advantage.
- Generic Manufacturers: Must analyze claim scope to assess potential infringement or design-around strategies.
- Legal and Patent Strategists: Should monitor potential opposition avenues or licensing opportunities.
- Regulatory Bodies: Recognize patent claims during drug approval processes and patent-term considerations.
Conclusion
AU2013274815 exemplifies a strategic patent protecting a novel pharmaceutical compound and its therapeutic application within the Australian legal framework. Its claims focus on specific chemical entities, methods of use, and formulations, aimed at securing a competitive position in the drug market.
The patent landscape surrounding this invention includes prior art challenges, requiring vigilant monitoring for potential infringements or oppositions. Its ultimate value depends on its enforceability, remaining patent term, and the ability to defend against challenges in Australia and internationally.
