Introduction
Patent KR20140026481 pertains to a pharmaceutical invention filed under South Korea’s patent system. Analyzing the scope, claims, and landscape surrounding this patent reveals insights into its strategic value, competitive positioning, and innovation domain — crucial for stakeholders engaging in licensing, litigation, or R&D.
Patent Overview and Filing Context
KR20140026481 was filed by a party seeking protection for a specific drug formulation, compound, or method likely aimed at a therapeutic area, possibly oncology, infectious diseases, or metabolic conditions, based on typical filings in the Korean pharmaceutics sector. The patent's publication number suggests a filing date in 2014 and public disclosure in 2014-2015.
South Korea’s patent examination process emphasizes clarity and incrementation of innovation. Patent applications often focus on improving efficacy, stability, delivery, or reducing side effects, especially within highly competitive sectors like pharmaceuticals.
Scope of the Patent
The scope of KR20140026481 is primarily defined by its claims, which encapsulate the legal boundary of the invention. It likely covers:
- Chemical Entity or Composition: Specific compounds, derivatives, or formulations.
- Method of Use or Manufacturing: Novel techniques for preparing or administering the drug.
- Combination Therapies: Aspects involving synergistic drug combinations.
- Delivery Systems: Innovative delivery mechanisms, such as sustained release or targeted delivery.
The claims' breadth or narrowness depends on how carefully the patent specifies the inventive features. Broad claims could encompass a wide range of compounds or methods, enhancing market coverage. Narrow claims focus on specific chemical structures or procedures, reducing infringing risks but limiting scope.
Claims Analysis
Dependence on Claim Numbering and Language:
While exact claim language is proprietary, typical patent claims for pharmaceutical patents can be categorized as:
- Independent Claims: Define the core invention—possibly a new compound or therapeutic method.
- Dependent Claims: Add specific limitations—such as particular dosage forms, administration routes, or molecular variants.
Likely Major Claims Structure:
-
Compound or Composition Claim
Claiming a novel chemical entity or a pharmaceutical composition comprising the compound with a specified carrier or adjuvant.
-
Method of Treatment Claim
Outlining a method of treating a disease by administering the compound, potentially with specific dosage regimes.
-
Formulation Claim
Covering specific excipients, stabilizers, or delivery mechanisms enhancing bioavailability or stability.
Claim Vulnerabilities and Strengths:
- Strengths: Precise chemical structures, innovative synthesis routes, or synergistic combinations provide defensible claims.
- Vulnerabilities: Overly broad claims risk invalidation if prior art is found; narrow claims afford limited protection but are more robust.
Claim strategy considerations:
Patent applicants often draft claims to cover not only the specific invention but also its obvious modifications, thus preventing circumvention.
