Method of Treatment Claims: Encompass the use of the compositions for treating particular doses, schedules, or disease indications.
-
Manufacturing Processes: Sometimes include claims related to the method of preparing the composition, focusing on novel synthesis techniques or formulation steps.
Legal Status and Expiration
The patent term extends 20 years from the filing date (2006), with the patent set to expire in 2026 unless novartis secures extensions—though Australia typically does not provide patent term extensions for pharmaceuticals.
Claims Analysis
General Characteristics of the Claims
The patent contains multiple independent claims, primarily focusing on:
- Specific chemical entities or their derivatives.
- Novel formulations combining known compounds with auxiliary agents.
- Methodologies for administering the compounds for a therapeutic effect.
Claim Scope and Limitations
-
Novelty and Inventive Step: The claims leverage a combination of structural features not previously disclosed, with inventive step grounded on improved bioavailability, reduced side effects, or enhanced efficacy.
-
Dependency and Dependent Claims: These narrow the scope further, adding specifics like dosage, formulation excipients, or combination partners.
Notable Claims
-
Independent Claim 1: Usually defines a composition comprising a specific active compound or combination that demonstrates a unique pharmacological profile.
-
Independent Claim 2: Might specify the treatment method, involving administration of the composition in certain medical circumstances.
-
Additional Claims: Cover variations such as different salts, polymorphs, or delivery systems designed to optimize therapeutic outcomes.
Claim Interpretation
-
Broad vs. Narrow Claims: The patent balances broad claims that cover general classes of compounds/methods with narrower claims protecting specific embodiments, to safeguard against potential invalidation and to secure enforceable rights.
-
Potential Challenges: Overlap with prior art or obvious modifications could face scrutiny, emphasizing the importance of detailed claim drafting.
