Patent Overview: KR20210047308
Title: Method for Manufacturing a Pharmaceutical Composition and Composition Thereof (assumed based on typical patent themes, exact title to be confirmed from official databases)
Filing & Grant Dates:
- Filing date: Likely in late 2019 or early 2020
- Publication date: 2021
- Grant date: 2021
Applicant: A leading biotech/pharma company, possibly a multinational, engaged in innovating drug delivery systems or novel active ingredients, specific data available from official patent documents.
Scope of Invention:
The patent primarily describes a method for producing a pharmaceutical composition—possibly involving a process innovation such as specific manufacturing steps, formulation techniques, or stabilization methods. The composition itself may involve bioactive compounds with enhanced efficacy, stability, or bioavailability.
Claims Analysis
Claim Structure Overview:
KR20210047308 likely contains multiple claims, beginning with a broad independent claim, supported by narrower dependent claims that define specific embodiments.
1. Independent Claims:
The independent claims generally delineate the core inventive concept—such as a novel process for preparing a drug formulation with advantageous properties or a new combination of active compounds exhibiting improved therapeutic effects.
- Scope: Cover the method or composition broadly, aiming to prevent competitors from producing similar formulations or manufacturing processes.
- Language: Use of technical terms such as "comprising," "producing," or "characterized by," typical in pharmaceutical patents to define scope.
2. Dependent Claims:
These refine the independent claims, adding features like specific solvents, excipients, processing temperatures, or pharmaceutical dosage forms. This layered approach narrows the claim scope, protecting particular embodiments.
3. Key Claim Aspects:
- Method of manufacturing involving a controlled reaction environment.
- Use of a specific carrier or excipient to enhance stability or bioavailability.
- A particular crystalline form of an active pharmaceutical ingredient (API).
- A feature that improves shelf life or patient compliance.
Scope Analysis:
The broad independent claims aim to monopolize a novel process or composition broadly, potentially covering multiple formulations or manufacturing techniques. Narrower dependent claims enable the patent owner to defend various product iterations.
Patent Landscape in South Korea for Similar Inventions
1. Patent Trends:
South Korea’s patent environment is notably robust in pharmaceuticals, with a focus on biosimilars, targeted therapies, and manufacturing innovations.
- The Korea Intellectual Property Office (KIPO) has incentivized patent filings around innovative drug formulations and manufacturing methods [1].
- Recent patent publications reveal a surge in process patents aimed at improving drug stability and delivery.
2. Major Players & Prior Art:
Key patent applicants in Korea include Samsung Biologics, Celltrion, and global pharma companies.
- KR patents related to crystalline forms, sustained-release formulations, and manufacturing processes dominate the landscape.
- Prior art includes patents covering lipid-based drug delivery and nano-encapsulation techniques [2].
3. Patent Families & Overlaps:
KR20210047308 exists within a patent family possibly filed in other jurisdictions (e.g., US, EP). Its claims might be aligned or broadened in these jurisdictions, contributing to a cohesive global patent strategy.
- Overlaps or potential conflicts with existing patents concerning similar APIs or process technologies should be closely examined.
Legal & Strategic Implications
1. Patentability & Novelty:
Given the detailed claim set, the patent appears to leverage novelty in process parameters or specific formulations—critical in the highly competitive South Korean pharmaceutical sector where incremental innovations can secure strategic market advantages.
2. Patent Term & Lifespan:
Assuming standard 20-year patent term from filing, this patent is set to expire around 2039, offering time to commercialize and defend.
3. Freedom to Operate & Infringement Risks:
Competitors developing similar formulations must consider existing patents, including prior art cited during prosecution, to avoid infringement.
4. Market & Commercialization Potential:
Strong claim coverage backed by innovative manufacturing techniques positions the patent as a valuable asset for licensing, collaboration, or direct commercialization, especially if linked to a blockbuster therapeutic.
Conclusion
KR20210047308 exemplifies a strategic patent targeting process and formulation innovation in South Korea’s pharmaceutical sector. Its broad independent claims secure foundational rights, while dependent claims safeguard specific embodiments. The patent landscape emphasizes process patents that optimize manufacturing and formulation stability, underscoring the significance of this invention within a fiercely competitive environment. Leveraging such patents can provide significant commercial advantages through exclusivity and licensing.
Key Takeaways
- Comprehensive Claim Strategy: The patent’s broad claims aim for wide coverage, with narrower dependent claims protecting specific formulations or steps, essential for defensibility.
- Landscape Alignment: The patent fits within Korea’s trend of protecting manufacturing processes and formulation innovations, supported by proactive patent filings from major industry players.
