- Filing and Grant Timeline: Filed in [specific year], granted in [specific year], reflecting a typical examination period.
- Assignee: Identifies the patent holder, potentially a multinational pharma corporation or biotech innovator.
- Jurisdiction: Singapore’s IP regime, under the Patent Act, adheres to stringent novelty and inventive step criteria, aligning with international standards.
Scope of Patent SG146656
The patent's scope delineates the boundaries of protection conferred to the inventor. This is predominantly encapsulated within its claims section.
Type of Innovation
- Likely covers either a novel pharmaceutical compound, a drug formulation, or a method of treatment/delivery.
- Could involve improved bioavailability, reduced side effects, or targeted delivery; such claims are common in contemporary patent filings.
Claim Structure and Technical Focus
Without access to the original document, the typical claims in patents similar to SG146656 tend to:
- Claims 1-3: Broad independent claims defining the core inventive concept—e.g., a chemical compound or composition with specific structural features or properties.
- Dependent Claims: Elaborate on specific embodiments, including salts, polymorphs, or formulation specifics, such as controlled-release mechanisms.
Example (hypothetical):
Claim 1: A pharmaceutical composition comprising a compound of Formula (I), wherein the compound exhibits enhanced bioavailability compared to prior art.
Claim 2: The composition of claim 1, further comprising a pharmaceutically acceptable excipient.
Claim 3: A method of administering the composition to a subject in need thereof to treat a specific disease.
Patent Claims Analysis
Claim Breadth and Validity
- Broad Claims: Intended to provide comprehensive coverage, but must be balanced against patentability standards for novelty and inventive step.
- Narrow Claims: Offer protection for specific embodiments, often easier to defend but less comprehensive.
Claim Specification and Support
- The detailed description likely supports these claims through experimental data, demonstrating the compound's efficacy, stability, or delivery mechanisms.
- Adequate support ensures robustness against validity challenges and reinforces enforceability.
Patent’s Novelty and Inventive Step
- The claims probably distinguish the invention from prior art by novel structural modifications, unique combinations, or application methods.
- For example, incorporating specific substituents or delivery vectors that improve therapeutic outcomes.
Patent Landscape Analysis
Global Patent Filings and Prior Art
- The patent landscape includes filings from jurisdictions such as the US, EU, China, and neighboring Asian markets, reflecting strategic patent coverage.
- Prior art searches reveal whether claims are truly innovative or represent incremental improvements.
Competitor and R&D Trends
- Many pharmaceutical patents in Asia target areas like oncology, infectious diseases, or CNS disorders.
- Hong Kong, Japan, and China mirror Singapore’s innovation trends, creating a dense IP environment with overlapping claims.
Cluster of Similar Patents
- Patents around specific chemical classes, delivery methods, or therapeutic targets form patent clusters that inform freedom-to-operate analyses.
- The presence of multiple patents in this space indicates intense R&D efforts and potential for licensing or patent litigation.
Patent Life Cycle and Maintenance
- The typical patent term is 20 years from the filing date, factoring in regulatory delays.
- Maintenance fees and prosecution history influence strength and enforceability over time.
