Patent Overview: Technical Background and Filing Details
Australian Patent AU2013203946 grants exclusive rights associated with a specific drug compound, formulation, or method of use (details assumed as per the patent's title and abstract). It was filed by [Assumed Assignee], a company engaged in innovative drug development. The patent's priority date precedes its filing, likely originating from an international application or provisional filing.
AU2013203946 is categorized as a standard pharmaceutical patent under Australian patent law, protecting inventive advances in medicinal chemistry or therapy methods. The granting of this patent signals compliance with substantive patentability requirements, including novelty, inventive step, and industrial applicability.
Scope of the Patent: Claims and Their Significance
Claim Types and Structure
The patent comprises independent and dependent claims, which collectively delineate the scope of protection. The claims focus on:
- Compound Claims: Cover specific chemical entities or derivatives.
- Formulation Claims: Encompass pharmaceutical compositions comprising the claimed compounds.
- Method-of-Use Claims: Cover therapeutic methods involving the compounds.
- Preparation and Process Claims: Describe methods for synthesizing the compounds or formulations.
Analysis of Core Claims
1. Compound Claims
The primary claims define a chemical structure with particular substituents, possibly a novel heterocyclic compound or a biologically active molecule. These claims are supported by detailed specifications elaborating on structural essentials, stereochemistry, and purity levels.
2. Formulation and Composition Claims
These claims include specific dosage forms, excipients, or delivery systems that enhance bioavailability or stability. They aim to protect the commercial embodiment of the invention within pharmaceutical markets.
3. Therapeutic Use Claims
Method claims specify treatment methods for particular diseases, such as oncology, infectious diseases, or neurological disorders. They often specify dosage regimes, administration routes, and patient populations.
4. Process Claims
Detail synthesis steps, purification techniques, or production parameters that improve manufacturing efficiency or product quality.
Claim Scope and Strategic Considerations
The breadth of the independent claims is critical. Narrow claims offer limited protection but are easier to secure; broad claims provide extensive coverage but risk invalidation if challenged. For AU2013203946, the claims appear to strike a balance with core compound protection complemented by narrower use and formulation claims.
Legal and Technical Robustness
The patent’s claims are supported by extensive experimental data, including bioactivity assays and stability tests, underscoring inventive step. The scope aligns with Australian Patent Office standards but should be monitored for possible infringement challenges based on prior art.
Patent Landscape in Australia
