- Biological targets: Specific receptors, enzymes, or pathways involved in disease modulation.
The scope likely encompasses both the chemical innovations and the methods of using these agents, providing broad protection for the inventive concepts.
Claims Analysis
In patent law, claims define the legal boundaries of the patent's protection. Analyzing the claims of WO2018034920 reveals the invention’s core novelty and inventive step.
Independent Claims
Typically, independent claims in medicinal patents articulate:
- The specific chemical structures or classes of compounds.
- The novelty features, such as specific substituents, stereochemistry, or conformations.
- The method of preparation or use in a therapeutic context.
For example, Claim 1 may describe a new chemical entity with particular substituent patterns demonstrating enhanced efficacy or safety profiles compared to prior art.
Dependent Claims
Dependent claims refine the scope by specifying:
- Particular pharmacokinetic properties.
- Formulation specifics (e.g., nanoparticle encapsulation, sustained-release matrices).
- Specific dosage regimens or treatment protocols.
- Additional combinations with existing drugs to improve therapeutic response.
Key Innovations in Claims
Initial review suggests the invention focuses on:
- A novel class of compounds with optimized binding affinity to biological targets.
- Enhanced pharmacological properties such as improved stability, bioavailability, or reduced toxicity.
- Unique delivery mechanisms aimed at tissue-specific targeting or controlled release.
Given the broad language often used in initial claims, the patent likely aims for wide protection across chemical variations and therapeutic uses, creating a robust barrier to competitors.
Patent Landscape Analysis
