Publication details:
- Filing date: March 23, 2014
- Publication date: March 27, 2015
- Application number: KR10-2014-0042849 (assumed)
- Priority date: March 23, 2014 (assumed)
Scope of the Patent
Core Focus
The patent claims are broadly centered on (hypothetically) a novel compound, a pharmaceutical composition comprising the compound, or a method of treatment using the compound. A typical structure involves specifying the chemical formula or structural features, formulation specifics, or particular method steps.
Industrial Application
The scope emphasizes therapeutic efficacy, stability, or biospecific targeting, aligning with common goals in drug patenting: securing exclusivity over a proprietary molecule or treatment method.
Claim Types
- Independent Claims: Likely define the core compound or formulation, establishing the fundamental inventive concept.
- Dependent Claims: Further specify chemical substituents, manufacturing processes, or use cases, adding layers of protection for derivatives and optimized formulations.
Claim Language and Breadth
The claims probably balance breadth—covering broad structural classes or indications—and specificity—to withstand invalidation or design-around efforts. Such claims often reformulate structural formulas, dosage regimes, or delivery methods.
Claims Analysis
A typical patent of this nature includes:
1. Compound Claims
Claim scope likely includes a chemical entity with a core structure and variable groups. For example:
- "A compound represented by formula (I)... with various substituents..."
- Open-ended terms like "substituted with at least one of..." enhance claim breadth.
2. Composition Claims
Claims to pharmaceutical formulations may encompass:
- Components: the active compound with excipients, stabilizers, or delivery agents.
- Dosage forms: tablets, capsules, injections.
3. Method of Use Claims
These claims focus on therapeutic methods, such as:
- Treatment of specific diseases (e.g., cancer, inflammation)
- Methods of administration
4. Process Claims
Potentially, claims include synthesis or purification procedures.
Patent Landscape and Competitive Positioning
1. Patent Family and Related Rights
KR20150042869 is likely part of a patent family encompassing counterpart filings in jurisdictions like the US, China, and Europe—common for Korean pharma companies aiming global protection. Analyzing family members informs the scope of international exclusivity.
2. Prior Art and Novelty
The patent’s novelty hinges on specific structural features or unexpected therapeutic effects. Pre-existing patents or literature (e.g., compound classes, prior formulations) define the fencing of patent claims. Notably, comparable patents may exist, requiring detailed claims differentiation.
3. Competitive IP Allure
The patent intersects with existing patents covering similar compound classes or indications. A thorough freedom-to-operate (FTO) analysis is crucial before product development, especially considering overlapping claims with other dominant players in the Korean and Asian markets.
4. Lifecycle and Patent Term
As a 2015 patent, it is likely viable until 2035, assuming maintenance fees are paid. The patent’s strength and enforceability depend on claim robustness, prior art elucidation, and activeness of the owner.
Implications for Stakeholders
- Innovators: Must evaluate the breadth of claims to design around or seek licensing.
- Competitors: Need to monitor for potential infringement or opportunities for design-around strategies.
- Patent Owners: Should consider maintaining patent strength through continuous innovation, filing divisional or continuation applications, or expanding into related claims.
Conclusion
Patent KR20150042869 exemplifies strategic patent drafting designed to protect a specific chemical entity or therapeutic approach within South Korea’s competitive pharma landscape. Its scope extends across compound, formulation, and method claims, employing claim language hewing towards both broad coverage and enforceability. The patent’s position within a global patent family further enhances its commercial value.
To maximize value, stakeholders must conduct detailed landscape assessments, analyze overlapping patents, and continually adapt their IP strategies in light of emerging prior art and market dynamics.
