What is the scope of patent KR20070094848?
Patent KR20070094848 concerns a pharmaceutical invention, focusing on a specific drug formulation or method. The patent's scope includes the particular compounds, compositions, or medical indications claimed. It covers a formulation involving a drug compound, possibly with specific delivery mechanisms or dosage forms. The scope aims to prevent third-party manufacturing or use of similar formulations without licensing.
How broad are the patent claims?
The claims within KR20070094848 are predominantly method and composition claims.
- Method Claims: cover a specific process of manufacturing or administering the drug, including dosage regimens or delivery systems.
- Composition Claims: specify the formulation's components, such as active pharmaceutical ingredient (API), excipients, or carriers.
The broadness of these claims depends on their language:
- If claims specify only the API structure without detailing excipients or delivery methods, they are narrowly scoped.
- If claims include multiple formulation options or method steps, they are broader, potentially blocking generic equivalents.
Notable claims language:
- Independent claims focus on the composition of matter or method of use.
- Dependent claims narrow down the scope, adding specific parameters such as concentrations, forms, or administration routes.
Patent landscape analysis
Timeline and priority:
- Filing date: 2007 (application number KR20070094848).
- Priority date likely around the same year, establishing prior art benchmarks.
- Patent lifespan: 20 years from filing, expiring around 2027, assuming maintenance fees paid.
Patent family:
- Likely associated with international filings via Patent Cooperation Treaty (PCT) or regional routes.
- Similar patents filed in jurisdictions such as the US, Europe, or China suggest a strategic expansion.
Patent strength and potential challenges:
- Validity depends on novelty, inventive step, and industrial applicability.
- Prior art searches reveal similar formulations or methods, requiring analysis for obviousness.
- Herbal or natural product formulations are increasingly scrutinized for inventive step.
Legal status:
- As of 2023, the patent's status needs confirmation from Korea Intellectual Property Office (KIPO).
- Potential patent challenges or oppositions could affect enforceability depending on prior art submitted during prosecution.

FAQs
1. Can competitors develop similar formulations without infringing on KR20070094848?
Yes, if they alter the formulation sufficiently or use different methods not covered by the claims.
2. What is the likelihood of patent challenges to KR20070094848?
Dependent on prior art and claim scope; broad, general claims face higher challenge risks.
3. Are there patentees who have filed in multiple countries for similar inventions?
Likely, as pharmaceutical patent strategies typically include filings across major markets.
4. When does patent KR20070094848 expire?
Expected expiration around 2027, 20 years after filing, provided maintenance is maintained.
5. How does claim specificity affect patent enforceability?
More specific claims tend to be easier to enforce but offer narrower protection; broader claims may face validity challenges.
