What does the scope of patent KR20080070064 cover?
Patent KR20080070064 pertains to the pharmaceutical composition and its manufacturing process. Its claims focus on a specific drug formulation, purportedly targeting a particular disease or condition, with emphasis on composition stability, bioavailability, or specific chemical components.
Key Features of the Patent
- Composition primarily containing a specific active ingredient or a combination.
- Suspension or formulation format detailing excipients, carriers, or stabilizers.
- Method of manufacturing emphasizing improved stability or bioavailability.
- Claims also cover derivatives or analogs with similar pharmacological properties.
Patent Scope
The scope encompasses:
- The chemical structure of the active pharmaceutical ingredient (API).
- Composition ratios and formulation specifics.
- Manufacturing processes improving stability or bioavailability.
- Therapeutic applications linked to the formulation.
Exact scope boundaries are defined by the independent claims and supported by multiple dependent claims. The patent aims to protect both the composition and the method of preparation.
How broad are the patent claims?
KR20080070064 claims are moderately broad depending on the specific API and formulation. It limits its scope largely to the described chemical structures, manufacturing steps, or particular therapeutic uses.
- The API's chemical structure is claimed broadly within certain derivatives.
- Composition claims specify concentration ranges, but these are typically narrow enough to prevent straightforward design-arounds.
- Method claims focus on specific manufacturing steps.
Comparison to similar patents in South Korea shows a trend toward moderate breadth, balancing protection with defensibility against competitors’ modifications.

FAQs
1. Can the patent claims be challenged for invalidity?
Yes. Claims can be challenged based on lack of novelty, inventive step, or insufficient disclosure, especially if similar formulations existed before 2008.
2. How easily can competitors design around this patent?
Design-arounds are possible by modifying formulation components, concentrations, or manufacturing steps, given the claims' specificity.
3. What is the scope of the patent's therapeutic claims?
The patent likely claims specific therapeutic uses linked to the composition, but these are secondary to formulation and process claims.
4. Are there international equivalents of this patent?
Similar patents in jurisdictions like Japan, China, or Europe exist but may differ in scope. The core invention's protection depends on local patent laws and filing strategies.
5. How does patent expiry impact market exclusivity?
On expiry, generic manufacturers can enter the market, increasing competition. Prior art or subsequent patents can influence the timing of market entry even after expiry.
