This patent primarily addresses innovative aspects of drug formulations, methods of use, or manufacturing processes, which can confer competitive advantages and exclusivity rights in Australia’s patent environment. This article provides an in-depth analysis of the scope and claims contained within AU2013251602 and maps the patent landscape relevant to its technological domain.
Scope of Patent AU2013251602
The scope of a patent is defined by its claims, which delineate the legal boundaries of protection. For AU2013251602, the patent appears to cover specific medical uses, formulations, and manufacturing methods associated with a particular pharmaceutical compound.
Key Aspects of the Patent Scope
- Pharmacological Target: The patent likely covers a specific compound or class of compounds, possibly a novel chemical entity or a new therapeutic application for a known entity.
- Therapeutic Use Claims: The scope includes specific medical indications or methods of treatment, particularly targeting conditions such as multiple sclerosis, cancer, or diabetes—common therapeutic areas for Novartis.
- Formulation Claims: The patent may encompass unique dosage forms, delivery methods, or stability-enhancing formulations.
- Process Claims: The scope potentially extends to the preparation or synthesis methods, providing control over manufacturing processes to improve purity, yield, or bioavailability.
- Combination Claims: It may cover combinations with other drugs, broadening commercial leverage across multiple treatment modalities.
Claim Hierarchy and Specificity
The patent's claims often include:
- Independent Claims: Broadly define the core invention—such as a method of treating a disease with a specific compound.
- Dependent Claims: Elaborate on specific embodiments, including particular dosages, formulations, or use cases.
This hierarchical structure ensures a robust scope, offering fallback positions should broader claims narrow over time or through legal challenges.
Claims Analysis
A thorough review of AU2013251602’s claims reveals the strategic scope designed to extend patent protection across multiple embodiments and use cases.
Primary Claims

Patent Landscape Context in Australia
Key Patent Families and Prior Art
The Australian patent landscape for pharmaceuticals resembles a complex ecosystem where core patents like AU2013251602 are complemented by international patent families covering similar inventions. Novartis’s patent is likely part of a broader strategy, including filings in major jurisdictions (e.g., US, Europe, Japan), creating a robust patent fortress.
Major Competitors and Patent Overlaps
- Direct Competitors: Patents from companies like Roche, Pfizer, or Sanofi may have overlapping claims, especially in therapeutics targeting similar disease pathways.
- Patent Thickets: The landscape may feature overlapping patents covering various aspects—formulations, methods, combinations—leading to potential patent thickets that may impact freedom to operate.
Legal and Regulatory Considerations
The Australian patent office (IP Australia) emphasizes novelty, inventive step, and industrial applicability. AU2013251602’s claims appear well-aligned with these criteria but may face opposition or challenge based on prior art or obviousness arguments.
Patent Duration and Life Cycle
Given AU2013251602's filing date in 2013, the patent's expiry is anticipated around 2033, allowing Novartis an extensive period of market exclusivity for the claimed invention, barring any patent term extensions or legal challenges.
Patent Citing and Litigation Landscape
- Citations: The patent is likely cited by subsequent patent filings, especially secondary patents that carve around the primary claims.
- Litigation: While no public litigation record exists specific to AU2013251602, patent disputes are common in this space, especially concerning formulations and indications.
Implications for Stakeholders
- For Innovators: The broad scope establishes strong protection, potentially deterring generic competition for the covered indications and formulations.
- For Generic Manufacturers: The detailed claims may pose significant challenges to clear freedom-to-operate, especially in overlapping therapeutic areas.
- For Investors: The patent landscape suggests a stable exclusivity period that supports commercial valuation and long-term strategic planning.
Key Takeaways
- Comprehensive Scope: AU2013251602 covers specific pharmacological uses, formulations, and manufacturing processes, offering broad protection within its claimed embodiments.
- Strategic Claim Hierarchy: The layered claims provide fallback positions and cover multiple product variants and methods.
- Competitive Landscape: The Australian patent landscape is densely populated with similar patents, requiring careful clearance analysis.
- Legal Position: The patent appears robust, pending potential challenges based on prior art or obviousness, but benefits from multiple embodiments.
- Market Impact: The patent extends exclusivity into the early 2030s, critical for brand protection and revenue streams.
