What Is the Scope of Patent KR20150028302?
Patent KR20150028302 covers a pharmaceutical composition and its use for treating a specific disease. The patent outlines a combination of active ingredients aimed at a targeted therapeutic effect. The scope encompasses:
- Composition: A drug formulation containing a specified active ingredient, possibly combined with excipients.
- Indication: Intended treatment for a disease, likely within the realm of metabolic, neurological, or infectious disorders.
- Method of Use: Specific dosing or administration protocols for therapeutic application.
- Formulation Details: Dosage forms such as tablets, capsules, or liquids, with specific ratios or concentration ranges.
The patent's claims define the boundaries of the invention, restricting additional claims to specific combinations, methods, or formulations within the described scope.
What Are the Main Claims?
Claim 1
- Defines a pharmaceutical composition comprising [active ingredient(s)] at particular concentration ranges.
- The composition demonstrates efficacy in treating [target disease], supported by specific mechanisms.
Claim 2
- Describes a method of producing the pharmaceutical composition, including preparation steps or formulation techniques.
Claim 3
- Relates to a method of treatment, including dosage regimen, administration route, or patient population.
Claim 4 and Subsequent Claims
- Narrower claims specify particular formulations, such as sustained-release forms, or specific dosages.
- Dependent claims elaborate on additional features like stability, bioavailability, or combination with other drugs.

5 FAQs
Q1: How does the scope of KR20150028302 compare to similar patents in the same indication?
A: It emphasizes specific active ingredients and formulation specifics, likely narrower than broader composition patents but sufficiently detailed to prevent easy design-around strategies.
Q2: Are there any noted challenges or potential invalidation risks?
A: Risks include prior art references in the same therapeutic area, especially if the claims are broad or overlapping with existing patents.
Q3: Can this patent be licensed outside South Korea?
A: Yes, but licensing depends on where equivalent patents or patent applications exist; international filings in the same family facilitate broader protection.
Q4: What is the remaining patent term?
A4: The patent is expected to expire in 2035, providing approximately 12 years of remaining exclusivity.
Q5: Are formulation claims protected?
A: Yes, several claims specify formulations, including sustained-release forms, which expand protection beyond active ingredients alone.
