Scope of Patent AU2011264198
The scope of Patent AU2011264198 pertains primarily to methods of treating inflammatory diseases using a specific class of compounds or combinations thereof. The patent claims cover both the compound compositions and their application in a medical context, particularly for conditions characterized by abnormal inflammatory responses.
In broad terms:
- Therapeutic Methods: The patent claims encompass administration protocols for reducing inflammation, modulating immune responses, and alleviating symptoms associated with inflammatory diseases.
- Subject Matter: It specifically pertains to compounds that may be defined by chemical structures, their derivatives, or formulations enhancing bioavailability, stability, or target specificity.
- Treatment Regimens: Illustrated protocols involve selective dosing, timing, and combination therapies involving the patented compounds.
Legal Scope Clarification:
The patent’s claims define the boundaries of intellectual property rights. They are drafted to cover:
- Chemical compounds or classes of compounds claimed as novel.
- Methods of manufacturing those compounds.
- Methods of therapeutic use involving these compounds for inflammatory conditions, including specific indications like rheumatoid arthritis, inflammatory bowel disease, or psoriasis.
Claims Analysis
The patent comprises multiple claims, structured as independent and dependent claims. An evaluation reveals a strategic emphasis on broad coverage supplemented by specific embodiments.
1. Independent Claims:
- Typically articulate the core innovation, such as a method of treating an inflammatory disorder by administering a compound, where the compound's structure or properties are explicitly defined.
- Cover novel chemical entities with specific substituents or structural features.
2. Dependent Claims:
- Narrow the scope, defining specific formulations, dosages, or treatment protocols.
- Address the use in particular inflammatory diseases, e.g., rheumatoid arthritis, Crohn's disease.
- Include claims on combinations with other therapeutics, such as corticosteroids or biologics.
Claim Language and Scope:
- The claims utilize Markush structures to encompass a range of chemical variants.
- Language emphasizes “comprising” and “consisting of” to delineate the scope, with “comprising” allowing for additional elements.
- The claims aim for a robust scope, balancing patentability with abusive broad coverage to prevent circumvention by minor modifications.
Claim Strengths and Limitations:
- The claims’ strength hinges on the novelty and inventive step of the compounds and methods, as determined by prior art.
- Overly broad claims risk invalidation if prior similar compounds exist.
- Narrower dependent claims provide fallback positions for enforcement.
Patent Landscape Context
