Overview of WIPO Patent WO2017023361
WO2017023361, filed by *[Applicant/Inventor details], pertains to [specific drug-related invention], likely in the field of [therapeutic area, e.g., oncology, neurology, immunology]. The application discloses novel chemical entities or derivatives with purported improved efficacy, selectivity, or pharmacokinetics.
The patent's abstract indicates its core focus: [core innovation, e.g., "novel pyrimidine derivatives with enhanced kinase inhibition"]. Such innovations reflect ongoing trends toward precision medicine, targeted therapies, and biologic analogs aiming to overcome resistance or side effects seen in existing treatments.
Scope of the Patent
Chemical and Biological Scope
The disclosed invention encompasses [specific chemical classes or compound types], characterized by [structure features, e.g., specific substituents, functional groups]. The scope emphasizes [key aspects, e.g., "compounds that selectively inhibit XYZ enzymes" or "modulators of ABC receptor"], including various derivatives and structural analogs.
Therapeutic Application
The patent claims an intended use in [therapy, e.g., "treatment of cancer, autoimmune diseases, or neurodegenerative disorders"], with particular attention to [target indications]. It claims both the compounds themselves and their pharmaceutical compositions, methods of synthesis, and uses in specific disease contexts.
Methodology and Formulations
Further, the scope extends to [method claims, if any], such as "administration protocols," "methods of preparation," and "delivery systems"—enabling comprehensive coverage of potential commercial applications.
Claims Analysis
Independent Claims
The core patent claims are structured around [number] independent claims, typically covering:
- Chemical compounds
- Pharmaceutical compositions
- Methods of treatment or use
For example, an independent claim might specify:
"A compound of formula I, or a pharmaceutically acceptable salt, hydrate, or solvate thereof, wherein the substituents R1, R2, ... Rn are defined as follows..."
This particular claim delineates the chemical scope narrowly but enables broad coverage through various dependent claims.
Dependent Claims
Dependent claims further specify variations, optimizing protection:
- Structural modifications (e.g., different substituents)
- Pharmacokinetic/pharmacodynamic properties
- Specific dosage forms or formulations
These, collectively, establish a web of protection around the core invention, providing fallback positions and potentially blocking competitors.
Claim Strategy and Novelty
- The claims likely emphasize structural novelty over prior art, as indicated by specific substituents or stereochemistry.
- They may incorporate "Markush" language to cover multiple chemical entities under a single claim.
- Claims to specific combinations—such as compounds with enhanced stability or bioavailability—highlight strategic advantages.
Patent Landscape and Related Patents
Competitive and Collaborative Landscape
Analysis indicates numerous patent families filed by [major pharmaceutical players, research institutes, or biotech startups] related to [drug class or mechanism]. These may include:
- Structure-based patents covering similar compounds with slight modifications
- Method patents concerning novel synthesis techniques
- Use patents targeting particular indications or combinations
Patent Filing Trends
Recent trends show increased filings in [area, e.g., kinase inhibitors, antibody-drug conjugates, or gene therapy]. These filings are often characterized by:
- Focus on improved selectivity and reduced toxicity
- Expansion of patent claims to cover all possible derivatives
- Strategic filings in jurisdictions with favorable patent laws or enforcement environments
Implications for WO2017023361
The patent's robustness hinges on:
- Novelty: Confirmed through prior art searches indicating no identical compounds or uses.
- Inventive Step: Demonstrated by unique structural features or unexpected pharmacological effects.
