2. Scope and Claims Analysis
2.1. Patent Claims Overview
Patent claims define the legal scope of patent protection. They include independent claims, which stand alone, and dependent claims, which narrow the protection.
Sample structure of claims (hypothetical based on typical drug patents):
| Claim Type |
Number |
Description |
Scope |
| Independent |
1 |
A therapeutic compound comprising [specific chemical structure or biological agent] |
Broad, covers all variants fitting the claim structure |
| Dependent |
2-10 |
Specific modifications, formulations, or uses of claim 1 |
Narrower, provides fallback positions or specific embodiments |
In KR20200069262:
- Likely features a composition or method involving a specific molecular entity
- Emphasizes the novelty in structure, synthesis process, or therapeutic utility
- May claim specific dosage or delivery system
2.2. Key Elements of the Claims
- Chemical Structure or Biological Target: Defines the precise molecular entity or biological pathway
- Method of Use: Specifies disease indications or diagnostic applications
- Formulation or Delivery System: Details related to composition stability, bioavailability, or administration routes
- Production Process: Novel synthesis or extraction mechanism
Implication: The breadth of these claims determines market exclusivity; overly broad claims risk invalidation, while narrow claims limit market scope.
2.3. Potential Patent Claim Strategies and Risks
