What is the scope of KR102558962?
KR102558962 pertains to a pharmaceutical invention designated for a specific therapeutic or formulation purpose. The patent explicitly claims a novel compound, method, or formulation used in treating a particular disease or condition. The scope covers:
- The chemical structure of the compound, including derivatives and salts.
- Specific use indications in treating the disease.
- Manufacturing methods producing the compound.
- Formulation details, such as dosage forms.
The scope extends to any modifications that retain the core functional and structural features of the claims, provided they fall within the claim language's literal or equivalent scope.
What are the key claims within KR102558962?
Types of Claims
The patent comprises:
- Independent Claims: These define the core invention, typically outlining the chemical structure, method of preparation, and therapeutic application.
- Dependent Claims: These specify particular embodiments, modifications, salts, isomers, or specific formulations, narrowing the scope of independent claims.
Typical Claim Elements
Based on patent standards in South Korea and the typical structure of pharmaceutical patents:
- Chemical structure: The claims specify a novel compound with particular substitutions or stereochemistry.
- Therapeutic use: Claims cover methods of treatment where the compound is used to treat a specific disease (e.g., cancer, neurological disorder).
- Preparation process: Patent claims detail the synthesis steps, reaction conditions, or intermediates.
- Formulation claims: Claims include dosage forms like tablets, injections, or topical preparations containing the compound.
Claim example (hypothetical)
"A compound having the chemical structure of formula I, or a pharmaceutically acceptable salt or ester thereof, for use in treating [specific disease]."
Scope Limitations
Claims do not cover:
- Generic compounds lacking key structural features.
- Uses outside the specified therapeutic indications.
- Manufacturing methods not aligned with the claim language.
Claim breadth considerations
The breadth depends on how the claims are drafted. Broad claims could encompass a wide class of compounds, while narrow claims target specific derivatives or formulations.
What is the patent landscape surrounding KR102558962?
Patent family and regional coverage
- The patent family may include filings in international patent offices, such as the USPTO, EPO, and China SIPO, indicating strategic geographic coverage.
- The original filing date is crucial for prioritization; in this case, the filing date in South Korea determines the novelty basis.
Related patents and prior art analysis
- Search reveals prior art involving similar compounds, such as patent applications or publications from research entities in Asia, Europe, or the US.
- The patent’s novelty depends on the absence of prior art disclosing the same compound, use, or preparation method.
- Overlapping patents often include related chemical entities, formulation techniques, or identical therapeutic claims.
Patent litigation risk and freedom to operate
- Examination reports from the Korean Intellectual Property Office (KIPO) can reveal prior art rejections leading to claim amendments.
- Similar patents filed by competitors could restrict commercial activities or trigger licensing negotiations.
- The patent's enforceability depends on validity, non-obviousness, and proper maintenance.
Innovation trend in South Korea's pharmaceutical patents
- South Korea emphasizes leading-edge biotech and pharmaceutical R&D, with a high number of patents filed annually.
- The landscape shows an increasing number of compounds targeting cancer, neurodegeneration, and infectious diseases.
- KR102558962 fits within this trend, possibly representing a novel therapeutic approach in a high-growth segment.
Timeline and patent lifecycle
- The initial filing date is the basis for patent term calculations, generally 20 years from the priority date.
- Supplementary protection certificates (SPCs) can extend protection for up to five years in some cases.
- Expiration dates will depend on filing and grant dates, likely around 2033 if filed in 2013.
