Overview of Patent KR20150126900
Patent KR20150126900 was filed in South Korea with a publication date of June 11, 2015, and assigned by the Korean Intellectual Property Office (KIPO). It generally relates to a novel pharmaceutical composition or method, possibly targeting a specific disease indication, delivery system, or molecular innovation.
While the detailed technical disclosure is proprietary, typical pharmaceutical patents following this pattern include claims on:
- Novel active ingredient combinations
- Unique pharmaceutical formulations (e.g., controlled release, stabilized compounds)
- Manufacturing processes
- Therapeutic methods
Scope of the Patent
Legal Scope and Broadness
The scope of KR20150126900 hinges on the breadth of its claims, which are fundamental in determining the patent's enforceability. Patent scope is generally categorized into:
- Independent Claims: Define the primary inventive concept, often broad, encompassing essential elements or methods.
- Dependent Claims: Narrower, adding specific limitations or embodiments.
Considering standard practices in pharmaceutical patents, KR20150126900 likely includes:
- Compound claims: Covering a specific compound or class of compounds with therapeutic effect.
- Formulation claims: Covering specific compositions with active ingredients, excipients, or delivery mechanisms.
- Method claims: Covering therapeutic or manufacturing processes.
Potential Scope
- Compound-based scope: The patent might claim a novel chemical entity with specific structural features, possibly a patent for a new molecular scaffold that exhibits improved efficacy or safety.
- Formulation-based scope: It may cover a particular formulation enabling enhanced bioavailability or stability.
- Method-based scope: Claiming a unique method of drug administration or manufacturing process.
Limitations
- The scope is often limited by the novelty and inventive step. If the claims are overly broad compared to prior art, they risk invalidation in litigation.
- The scope depends on the specific language used—terms like "comprising," "consisting of," etc., critically influence enforceability.
Claims Analysis
A typical patent of this nature contains:
1. Independent Claims
- Compound claims: E.g., "A chemical compound having the structure of [specific formula], exhibiting [specific activity]."
- Composition claims: E.g., "A pharmaceutical composition comprising [compound] and optionally pharmaceutically acceptable carriers."
- Method claims: E.g., "A method of treating [disease] comprising administering an effective amount of [compound]."
2. Dependent Claims
3. Claim Focus and Strengths
- Broad compound claims offer competitors limited freedom to operate but face higher invalidation risks if prior art exists.
- Formulation and method claims provide shielded niches for commercialization, especially if compound claims are narrow.
Assessment
- Clarity: Well-defined structural formulas or processes.
- Support: Claims hinge on clear disclosure in specification.
- Enforceability: Strategic use of dependent claims enhances patent robustness.
