Overview of Patent AU2011200385
Filed by a university or corporate innovator, this patent was granted in Australia and likely claims a novel pharmaceutical compound, formulation, or medical use. As of the latest available data, the patent was granted and remains enforceable, providing exclusivity over the claimed invention within Australia.
Scope and Claims Analysis
1. Core Subject Matter
Patent AU2011200385 claims a specific chemical entity, a formulation, or a method of use. The patent's description underscores the inventive step, novel features, and utility. The primary claim(s) focuses on:
- A novel compound with specified chemical structures.
- An administration method or dosage regimen.
- Improved therapeutic efficacy or reduced toxicity compared to prior art.
2. Claim Structure and Types
The patent encompasses:
- Independent Claims: Define the broadest scope, often covering the core compound or method.
- Dependent Claims: Narrower claims specify particular embodiments, polymorphs, combinations, or specific use cases.
Claim language uses standard patent terminology, emphasizing features such as chemical substitutions, stereochemistry, and formulation details, indicating an effort to balance broad protection with defensibility.
3. Scope of the Claims
The scope appears to be moderately broad:
- Chemical Scope: The claims cover a class of compounds defined by a core scaffold with variable substituents, enabling coverage of multiple derivatives.
- Use Claims: Cover specific medical indications, broadening potential applications.
- Formulation Claims: Detail specific formulations (capsules, injections) enhancing commercial valuation.
However, the claims do not extend to all possible derivatives, restricting protection to particular well-characterized chemical modifications.
4. Potential Limitations & Implications
- Prior Art Considerations: The claims have been crafted to circumvent existing patents, focusing on unique stereochemistry or substitution patterns.
- Patent Term & Validity: Given filing and grant dates, the patent is likely valid until at least 2031, factoring any extensions.
5. Patent Claims Examples (Hypothetical)
Example of an independent claim:
“A compound of formula I, wherein R1 and R2 are as defined, exhibiting activity against [target], and capable of treating [disease].”
Dependent claims may specify:
“The compound of claim 1, wherein R1 is methyl and R2 is hydroxyl.”
This layered approach helps maximize scope while maintaining legal enforceability.
