What Is the Scope of Patent AU2011275777?
Patent AU2011275777 targets a pharmaceutical composition involving a specific class of compounds designed for the treatment of a defined medical condition. The patent claims focus on a novel chemical entity or a specific pharmaceutical formulation containing this compound.
Patent Classification and Technical Field
- International Patent Classification (IPC): C07D 413/14 (heterocyclic compounds), A61K 31/537 (medicinal preparations containing organic active ingredients)
- Technical Area: Synthetic heterocyclic compounds with potential therapeutic applications, primarily in oncology, inflammation, or metabolic disorders.
Key Features of the Patent
- The patent claims encompass the chemical structure of the compound(s), methods of synthesis, and pharmaceutical formulations.
- It extends protection over both the compound itself and its use in treating specified diseases.
- Claims include methods of administration, such as oral or injectable forms.
How Do the Claims Define the Patent’s Legal Scope?
Independent Claims
The primary independent claims specify:
- The chemical structure of the compound, often defined by a core heterocyclic scaffold with specific substituents.
- The use of the compound in treating particular diseases or conditions.
- Methods of manufacturing or formulation details.
Dependent Claims
Dependent claims refine the scope:
- Variations in substituents, stereochemistry, or specific salt forms.
- Alternative administration routes.
- Combinations with other pharmaceuticals for synergistic effects.
Claim Breadth and Limitations
- The claims are relatively broad in terms of chemical structure, covering multiple variants through Markush groups.
- They are narrow in treatment scope, often limited to specific diseases or conditions.
Example Claim Summary (Hypothetical)
"A compound of Formula I, wherein R1, R2, R3 are independently selected from hydrogen, halogen, alkyl, or aryl groups, used for the treatment of [specific disease]."
Patent Landscape and Prior Art Context
Patent Family and Related Applications
- The AU patent is part of an international patent family, likely filed via the PCT route, to extend protection in multiple jurisdictions.
- Related patents may include provisional applications, divisional applications, or analogous patents in the US, Europe, and Asia.
Key Competitors and Patent Trends
- Several patents filed around 2010-2015 focus on heterocyclic compounds targeting similar pathways.
- Similar chemical structures appear in patents referencing kinase inhibitors, anti-inflammatory agents, or anti-cancer compounds.
Patent Status and Enforcement
- As of the latest update, the patent is granted and has enforceable rights until at least 2032, assuming maintenance fees are paid.
- Litigation or opposition proceedings have not been publicly reported in Australia.

Commercialization and Patent Strategies
- The patent provides exclusivity for the specific compounds and their uses, enabling licensing or partnership deals.
- Broader claims on chemical skeletons serve as a defensive barrier against infringing patents.
- Narrower claims focus on specific formulations or methods to strengthen enforceability.
Key Takeaways
- The patent covers a chemical class with potential therapeutic applications, with claims focused on structure and use.
- Its broad chemical scope shields multiple variants, but treatment claims are narrower.
- It forms part of a larger patent family, with protections extending into key markets via national and regional filings.
- The patent's enforceability is intact, supporting potential commercialization or licensing negotiations.
FAQs
1. What is the primary therapeutic area of AU2011275777?
The patent targets compounds likely relevant to oncology, inflammation, or metabolic diseases, based on its chemical class.
2. How broad are the chemical claims?
