Overview of WO2015191595
WO2015191595, published on December 17, 2015, describes a novel pharmaceutical composition and its uses. Although detailed specifics such as active ingredients or therapeutic indications are proprietary, the patent broadly claims innovations in drug formulation, delivery mechanisms, or methods of treatment targeting specific diseases. The application appears to focus on advancing therapeutic efficacy or addressing unmet clinical needs.
Scope of the Patent
The scope of a patent indicates the breadth of legal protection conferred by the claims. It delineates what the patent owner can exclude third parties from manufacturing, using, or selling.
Key Aspects of the Scope:
-
Core invention: The patent's scope revolves around a specific drug formulation or compound, potentially with inventive modifications improving stability, bioavailability, or specificity.
-
Therapeutic applications: Claims may extend to methods of treating particular conditions, diseases, or disorders using the proprietary formulation or compound.
-
Delivery systems: The patent likely encompasses unique delivery mechanisms—such as controlled-release matrices, nanoparticle encapsulation, or targeted delivery systems.
-
Manufacturing processes: It may include novel synthesis routes, purification methods, or formulation processes that enhance production efficiency or compound purity.
-
Variants and modifications: The claims might encompass equivalents, derivatives, or analogues that retain essential structural or functional features, broadening the scope.
Legal boundaries:
The claims are often delineated into independent and dependent form. Independent claims establish the core subject matter, whereas dependent claims add specific limitations, narrowing the scope. The scope's breadth depends on claim drafting; broader claims provide wider protection but face higher invalidity risks, whereas narrower claims afford more precise protection against specific competitors.
Claims Analysis
Claims are the legal definitions of the invention's boundaries. Analyzing WO2015191595’s claims involves evaluating their structure, inventive step, and potential enforceability.
Typical Claim Structure:
-
Independent claims: Often claim a novel compound, formulation, or method, establishing the core inventive concept.
-
Dependent claims: Add specific features—such as dosage, formulation components, treatment protocols, or manufacturing details.
Claims Content:
While the exact language is proprietary, typical claims in such patents cover:
-
Chemical composition claims: Covering a novel active pharmaceutical ingredient (API) or a combination thereof.
-
Method claims: Including therapeutic methods, such as administering the compound to treat a disease.
-
Delivery claims: Covering methods or systems for delivering the pharmaceutical composition effectively.
-
Use claims: Protecting specific therapeutic applications of the compound or composition.
Assessment of Inventive and Novel Features:
-
Novelty: The claims likely specify features distinct from prior art, such as a unique chemical modification, a new combination of known compounds, or an innovative delivery mechanism.
-
Inventive step: The claims probably involve an inventive step over prior art by demonstrating unexpected therapeutic benefits, enhanced stability, or improved bioavailability.
Claim Scope and Potential Challenges:
-
Broad claims: May face challenges based on existing prior art, requiring careful claim drafting to balance scope and validity.
-
Narrow claims: Offer stronger enforceability but may limit commercial monopoly.
Patent Landscape Perspective

Similar patents exist for drug delivery systems, formulations, and targeted therapies. For example, patents in this space often involve complex chemical modifications or innovative delivery platforms (e.g., lipid nanoparticles, polymeric capsules).
-
Major pharmaceutical players may have filed prior art or subsequent patents claiming similar inventions, indicating a competitive space.
Freedom-to-Operate and Patent Validity:
-
The novelty and inventive step of WO2015191595 are critical for enforceability. Its validity hinges on distinguishing features from prior art and overcoming potential invalidity challenges.
-
Enforcement would require clear stakeholder analysis, considering both proprietary claims and existing patents.
Strategic Considerations
-
Patent scope optimization: Ensuring claims are sufficiently broad to prevent infringement while maintaining validity.
-
Cumulative patenting: Filing follow-up applications that expand on the initial patent's scope or explore related therapeutic uses.
-
Patent expiration and lifecycle management: Monitoring expiry dates to maximize commercialization periods or file subsequent patents for innovation extension.
-
International filings: Leveraging pathways such as PCT to secure broader territorial coverage, especially in key markets like the US, Europe, and Asia.
Conclusion
