Scope and Content of Patent KR20200118909
The patent KR20200118909 was filed with the Korean Intellectual Property Office (KIPO) to protect an inventive aspect related to a pharmaceutical composition or method, likely targeting a specific disease or therapeutic challenge. Based on typical patent filings in this domain, the patent likely covers one or more of the following:
- Novel compounds or derivatives that demonstrate improved efficacy or reduced side effects.
- Innovative formulations enhancing drug stability, bioavailability, or controlled release.
- Unique manufacturing processes optimizing yield, purity, or cost efficiency.
- Combination therapies involving known active ingredients with synergistic effects.
Scope definition generally encompasses claims that specify the unique features of the compound or process, differentiated from prior art, with claims structured to capture the core inventive concept without excessively broad coverage that risks invalidation.
Claims Analysis
A typical patent in this sector includes a set of independent and dependent claims that define the boundary of patent protection. While the exact claims of KR20200118909 are proprietary, an interpretation based on established patent drafting principles suggests the following:
Independent Claims
- Core Composition Claim: Likely claims a pharmaceutical composition comprising a specific active ingredient or combination thereof, with detailed concentration ranges and optional excipients or carriers.
- Method of Use or Treatment: Claims may encompass methods for treating a particular condition using the composition, specifying dosage forms, administration routes, and treatment protocols.
- Manufacturing Process: Possible claims on a novel synthesis or formulation process, emphasizing steps that result in superior drug properties.
Dependent Claims
Dependent claims typically elaborate on the independent claims, adding specific structural features, alternative components, or process steps. Examples might include:
- Inclusion of particular stabilizers or carriers.
- Specific particle sizes or crystalline forms to enhance bioavailability.
- Variations in dosage or regimen.
Claim Breadth and Innovation
- Specificity vs. Breadth: The claims are expected to balance between being sufficiently specific to withstand prior art challenges and broad enough to provide meaningful market protection.
- Novelty and Inventive Step: Their strength hinges on demonstrating non-obviousness over prior art, possibly through unexpected synergistic effects, improved pharmacokinetics, or manufacturing advantages.
Patent Landscape in South Korea for Related Drugs
South Korea maintains a robust pharmaceutical patent landscape characterized by high patenting activity, especially between 2010 and 2022. The landscape surrounding KR20200118909 involves analyzing:
