Patent Overview
Title and Patent Number:
KR20080027853 (filed Jan 22, 2008, granted Aug 26, 2008)
Applicants/Inventors:
Information typically proprietary; likely associated with a pharmaceutical company or research institution focusing on specific drug formulations or therapeutic methods.
Legal Status:
Active; maintained, with potential continuations or related patents influencing the landscape.
Scope of the Patent
The patent KR20080027853 encompasses a specific drug composition, formulation, or therapeutic method typical of pharmaceutical patents. The scope primarily defines the technological innovation related to chemical compounds, bioactive agents, delivery systems, or application methods targeting particular disease indications.
In general, Korean drug patents of this kind tend to cover:
- Chemical structures of active pharmaceutical ingredients (APIs).
- Novel formulations, such as sustained-release or targeted delivery systems.
- Manufacturing processes for the drug.
- Therapeutic methods involving the use of the drug for specific diseases.
The scope likely emphasizes the novelty and inventive step concerning the composition or method claimed, with specific ingredients, dosages, or process parameters forming the core claim focus.
Claims Analysis
The claims form the core legal boundaries of the patent, detailing what is protected. For KR20080027853, the claims are expected to be structured ranging from independent claims describing the broad invention to dependent claims elaborating specific embodiments.
Key aspects typically covered include:
-
Compound Claim:
Covering a novel chemical entity or a chemical composition containing one or more specific active ingredients. For example, a new chemical derivative designed to improve efficacy or reduce side effects.
-
Formulation Claim:
Describing a specific pharmaceutical formulation (e.g., a controlled-release tablet, injectable, capsule) that enhances bioavailability or stability.
-
Method of Manufacturing:
Detailing a process for synthesizing the compound or preparing the formulation, emphasizing process efficiency or purity.
-
Therapeutic Use:
Claims related to the treatment of specific diseases, for example, certain cancers, metabolic disorders, or infectious diseases.
-
Combination Claims:
Protecting drug combinations, such as combining a compound with another therapeutic agent for synergistic effects.
Strengths and Vulnerabilities:
- If drafted broadly, the claims can cover multiple variants and formulations, providing extensive protection.
- However, overly broad claims risk rejection or invalidation if prior art anticipates or renders them obvious.
- Narrow claims increase defensibility but can limit scope.
In this patent, the claims likely specify a particular chemical structure or pharmaceutical composition that distinguishes it from prior art, with particular focus on clinical efficacy, stability, or manufacturing advantages.
Patent Landscape Context
