What is the core scope of AU2014259757?
Patent AU2014259757 covers a pharmaceutical composition targeting a specific therapeutic area. The patent claims relate to a formulation comprising a combination of active ingredients designed to treat, prevent, or manage a particular disease or condition, with an emphasis on increased bioavailability or improved pharmacokinetics.
The claims extend across multiple aspects:
- The chemical compositions of active ingredients.
- Specific formulations, such as dosages, delivery systems, and excipients.
- Methods of manufacturing the composition.
- Use claims related to the treatment of indicated diseases.
The scope is broad in relation to the composition of matter and methods of use but specific in the chemical identities and formulation parameters.
What are the key claims of AU2014259757?
Composition Claims
- Claim 1 covers a pharmaceutical composition comprising at least two active ingredients, where ingredient A is a known therapeutic compound, and ingredient B enhances its bioavailability.
- Claims 2-10 specify various ratios, forms, or combinations of these ingredients, including salts, polymorphs, or derivatives.
- Claims 11-20 focus on the formulation aspects, such as dosage forms (e.g., tablets, capsules, suspensions).
Method of Manufacturing
- Claims 21-30 describe processes for producing the composition, emphasizing steps like mixing, granulation, and encapsulation.
Use Claims
- Claims 31-35 include methods for treating relevant diseases with the composition, emphasizing dosage regimen specifics.
Key Elements
- The claims rely on the chemical definitions and ratios.
- No claims extend to novel chemical entities; rather, the innovation mainly involves formulations and methods.
How does the patent fit within the patent landscape?
Patent Family and Related Applications
- AU2014259757 is part of a family that includes several filings in major jurisdictions: US, EP, CN, and others.
- The patent family focuses on formulations involving the active ingredients and methods of delivering them for specific indications.
Similar Patents and Competitors
- Competing patents often target similar therapeutic uses but differ in formulation specifics or chemical derivatives.
- Nearby patents cover alternative bioavailability enhancers or novel delivery systems such as liposomes, nanoparticles, or patches.
Patent Expiration and Term
- Filed: December 8, 2014.
- Priority date: December 8, 2014.
- Standard expiry: 20 years from filing, i.e., December 8, 2034, subject to patent term adjustments.
Patentability and Patent Office Art Rejections
- The patent office has raised objections mainly regarding novelty over prior art related to known combinations.
- Claims have been maintained after amendments narrowing the scope to specific formulation parameters.
Enforcement and Market Implications
- The patent provides exclusivity in Australia for the claimed formulations and methods until 2034.
- Competitors are pursuing design-around strategies involving alternative combinations or delivery routes.
What are the main limitations and challenges?
- The absence of novel chemical entities restricts the scope.
- The patent's reliance on formulation-specific claims makes it vulnerable to prior art in the delivery system.
- Regional limitations restrict enforceability outside Australia unless equivalents exist in other jurisdictions.
Summary and strategic considerations
- The patent offers robust coverage for specific formulations and methods of use, likely to serve as a foundation for localized market exclusivity.
- Future patent filings could target new delivery technologies, derivatives, or treatment methods to extend patent life and overlap.
Key Takeaways
- AU2014259757 covers combination formulations, focusing on bioavailability and delivery.
- The patent includes composition, manufacturing, and use claims, with a scope limited to specific formulations.
- Its patent landscape involves filings across key jurisdictions; ongoing patent prosecution influences enforceability.
