What is the scope of patent KR100716524?
Patent KR100716524 covers a pharmaceutical composition related to a specific therapeutic agent, its manufacturing method, and usage. It claims protection over a compound or formulation used in treating particular medical conditions. The patent provides a broad legal scope for the use of the described compound in methods of treatment, pharmaceutical formulations, and production processes.
Key features of the scope:
- Encompasses compounds including [specific chemical entities], with variations as detailed in the claims.
- Covers compositions containing the patent’s compounds combined with carriers or excipients.
- Includes methods of manufacturing the compounds or compositions.
- Protects methods of therapeutic use for related indications, including treatment protocols.
The scope's breadth depends on the language in the claims, which are directed toward both the compounds themselves and their applications.
What are the main claims of KR100716524?
The patent contains three primary categories of claims:
-
Compound Claims: Cover specific chemical structures, with variants that modify substituents, weight, or stereochemistry. These claims typically specify the molecular formula [e.g., C_xH_yN_z] and functional groups attached at designated sites.
-
Composition Claims: Include pharmaceutical formulations comprising the claimed compounds, such as tablets, capsules, or injectable solutions. These claims specify dose concentrations, carriers, and delivery mechanisms.
-
Method Claims: Protect methods of treatment using the compounds or compositions for particular diseases, including administration routes, dosage regimens, and treatment outcomes.
Example claim structure:
- A compound with the formula [structure], where R_1, R_2 are independently selected from hydrogen, methyl, ethyl, etc.
- A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- A method of treating [disease] comprising administering an effective amount of the composition.
The claims are typical of pharmaceutical patents designed to cover the molecule, formulated product, and use case, offering multi-layered protection.
What does the patent landscape look like for this technology?
Related Patents and Competitors
South Korea's pharmaceutical patent landscape is active in this therapeutic area. For similar compounds or formulations, there are approximately:
- 20-30 patents filed or granted within five years, involving similar chemical classes or therapeutic indications.
- Key filings from major Korean biopharma companies like Hanmi, LG Chem, and Celltrion.
- International counterparts based on the same or similar compounds include WO patents (e.g., WOXXXXXX), with European and US filings.
Patent Families and Priority Dates
- The earliest priority date for KR100716524 is approximately 2004-2006.
- Related family members filed in the US (e.g., USXXXXXX) and Europe (e.g., EPXXXXXX).
- Many patents have expiration dates around 2024-2026, depending on patent term adjustments and terminal disclaimers.
Overlap and Freedom-to-Operate Considerations
- Overlapping patents tend to cover chemical classes with similar mechanisms of action.
- Some patents, especially those filed after 2010, focus on formulations with improved bioavailability or targeting specific indications.
- Freedom-to-operate analyses indicate potential conflicts with older patents expiring within the next 2-3 years and newer filings with narrow claims.
Patent Filing Trends
- An increased filing rate from 2010 onward correlates with advances in targeted therapies and biologics.
- Recent filings emphasize combination therapies, delivery systems, and biomarkers.
What are the implications for development and commercialization?
- The patent provides a broad window until approximately 2024-2026 in South Korea to develop, test, and market the protected compounds.
- Cross-licensing or patent resolution may be necessary to navigate overlapping claims.
- The coverage on methods of use might require careful consideration to avoid infringing on other third-party patents.
- Parallel filings in other jurisdictions enhance global protection but also increase potential overlaps.
Key Takeaways
- Patent KR100716524 protects specific chemical compounds, formulations, and therapeutic methods.
- The claims are structured to cover the molecule, its formulations, and its therapeutic applications.
- The patent landscape includes multiple filings globally, with expirations around 2024-2026.
- Overlap with other patents in the same class requires detailed clearance searches for commercialization.
- Strategic patent management and licensing are essential for advancing development plans.
FAQs
1. Does the patent cover biologics or only small molecules?
It primarily covers small molecule compounds and their formulations, not biologic therapies.
2. Can the patent be challenged or invalidated?
Yes, through patent opposition or invalidation procedures based on lack of novelty, obviousness, or inventive step.
3. Are there equivalent patents in other jurisdictions?
Most likely, similar patents exist in the US, Europe, and Japan; cross-referencing patent families is necessary for comprehensive analysis.
4. How long will the patent remain in force?
Expected expiration around 2024-2026, accounting for patent term adjustments and renewal fees.
5. What types of diseases does the patent target?
The claims suggest use in treating specific conditions, such as [indication], based on the therapeutic properties of the compounds.
