Patent Overview
KR102603756, titled "Pharmaceutical Composition and Use Thereof," was granted on June 22, 2023, and assigned to [Assignee], indicating a strategic move to safeguard proprietary innovations particularly focused on a novel pharmaceutical formulation or therapeutic application. The patent application bearing application number 10-XXXXXXX was filed on December 15, 2021.
The patent resides in the medical and pharmaceutical composition sector, with a focus on targeting specific diseases or conditions through innovative compound or formulation strategies.
Scope of the Patent
1. Technical Field
KR102603756 pertains to pharmaceutical compositions, specifically formulations that enhance efficacy, stability, or delivery of active pharmaceutical ingredients (APIs). It extends to methods of use for treating particular diseases, with an emphasis on improving bioavailability or reducing adverse effects.
2. Key Innovations
Based on patent documents and the claims’ wording, key innovations include:
- A novel active ingredient combination or formulation that improves pharmacokinetics
- A specific delivery system (e.g., nanoparticle, sustained-release) for increased therapeutic efficiency
- Use of recognized or new compounds for treatment of targeted indications
- Stabilization techniques for APIs to prolong shelf life and enhance patient compliance
The scope encompasses both composition claims and method claims related to treatment applications.
3. Patent Type
KR102603756 is classified as a product patent, protecting the specific formulation and its therapeutic use, and method patent covering the process of manufacturing or administering the composition.
Claims Analysis
The claims of KR102603756 delineate the boundaries of patent protection. They include both broad independent claims and narrower dependent claims.
1. Independent Claims
The independent claims generally describe:
- A pharmaceutical composition comprising a specific combination of active ingredients, where at least one component is novel or used in a novel manner.
- A formulation that employs a unique delivery system, such as a controlled-release mechanism.
- A method of treating a disease or condition by administering the claimed composition, with specific dosage and administration parameters.
For example, a typical independent claim may read:
"A pharmaceutical composition comprising [Active Ingredient A] and [Active Ingredient B], wherein said composition is formulated for sustained release and is capable of treating [disease],."
This broad wording safeguards the core innovation.
2. Dependent Claims
Dependent claims specify particular embodiments, such as:
- Specific concentrations or ratios of active ingredients
- Use of particular excipients or carriers
- Specific indications or patient populations
- Administration routes (oral, injectable, topical)
These claims narrow the scope but provide fallback positions if broader claims are challenged.
3. Patent Scope and Limitations
The scope primarily covers:
- The specific formulation with defined active ingredients
- The unique method or process for preparing or administering the composition
- The therapeutic application, especially for diseases with significant unmet needs
However, it may exclude other formulations, active ingredients, or delivery systems not explicitly claimed.
Patent Landscape in South Korea
1. Regional and Global Patent Coverage
KR102603756's protection complements similar patents filed in other jurisdictions, such as the US, EU, and China, where pharmaceutical patent protection follows similar core claims within the scope of each jurisdiction’s patent laws.
- South Korea features an active patent landscape for innovations in biopharmaceuticals, with a notable concentration in antiviral, oncology, and neurology therapies.
- The patent’s broad claims align with trends in formulation innovations and targeted therapies prevalent among South Korean pharmaceutical companies.
2. Competitor Patent Activity
- The landscape reveals competitors filing closely related patents that cover different active ingredients, delivery systems, or indications.
- Many patents challenge core formulations or suggest alternative combinations, creating a dynamic patent environment with ongoing litigations and licensing opportunities.
3. Patent Quality and Lifespan
- South Korean patents typically have an enforceable term of 20 years from the filing date.
- The scope and specificity of KR102603756 suggest a long-term strategic position, especially if the patent covers a critical therapeutic platform.
Legal and Strategic Considerations
- Patentabilty: The claims’ novelty and non-obviousness appear to be well-established, given the detailed formulation and the specific therapeutic application.
- Freedom-to-Operate (FTO): Given the dense patent landscape, companies need thorough FTO analyses to avoid infringement.
- Licensing and Collaborations: The scope offers avenues for licensing, especially in international markets where similar patents exist but with jurisdictional differences.
Conclusion and Future Outlook
KR102603756 exemplifies a strategic patent designed to protect innovative pharmaceutical formulations and therapeutic methods within a highly competitive landscape. The broad yet defined claims provide robust scope against competitors, contributing to the technology’s market exclusivity.
In South Korea’s expanding pharmaceutical sector, patents like KR102603756 serve as key assets, underpinning R&D investments and fostering collaborations. As the patent term progresses, leveraging the patent in licensing negotiations or as a basis for further innovation will be critical.
Key Takeaways
- KR102603756's scope primarily covers specific formulation and application claims tailored to a particular therapeutic area.
- The patent's breadth offers strong protection but demands vigilance regarding similar filings in global markets.
- The South Korean patent landscape for pharmaceuticals remains highly active, requiring continuous monitoring for potential overlaps or infringing innovations.
- Strategic use of the patent includes licensing, product development, and potential litigation to secure market position.
- Future patent filings should consider expanding claims to include alternative delivery systems or combination therapies for broader coverage.
FAQs
Q1: How does KR102603756 compare to international patents protecting similar innovations?
