Scope of the Patent: Claims and Their Implications
1. Core Claims – Composition or Compound
The primary claims of SG1888252379 typically claim a novel chemical entity which exhibits specific biological activity, such as anti-inflammatory, anti-cancer, or antiviral properties. These claims are usually broad, covering the compound's chemical structure, including specific substitutions that enhance efficacy or reduce toxicity.
-
Scope: The claims likely encompass the compound's structural formula, including stereochemistry and specific substituents, with possible claims to derivatives, salts, or prodrugs.
-
Implications: Broad claims on the core compound establish fundamental protection, preventing the entry of close analogs or structurally similar compounds within this core framework.
2. Formulation and Use Claims
Secondary claims possibly extend to pharmaceutical compositions, delivery methods, or specific formulations (e.g., sustained-release formulations).
-
Scope: These claims protect specific ways of administering or formulating the compound, such as encapsulation, combination with excipients, or targeted delivery mechanisms.
-
Implications: Such claims safeguard the commercial application and manufacturing strategies, potentially covering a wide range of product formats.
3. Method of Treatment Claims
Tertiary claims often involve methods of treating specific diseases or conditions with the compound.
-
Scope: Protects the method of administration, dosage, and treatment regimen.
-
Implications: These claims are valuable for clinical and therapeutic protection, especially during regulatory approval phases.
4. Patent Exclusions and Limitations
Claims may specify exclusions to prevent overlap with known compounds or prior art, notably:
Limitations here narrow the scope and strengthen enforceability against prior art considerations.
Patent Landscape for Relevant Therapeutic Class
1. Patent Activity in Singapore and Southeast Asia

-
Local filings tend to cluster around the same target indications and compound classes, underscoring competitive development.
-
The presence of filings in countries like Malaysia, Indonesia, and Thailand reveals regional strategic interest, driven by patent harmonization efforts (e.g., ASEAN Patent Cooperation Treaty).
2. Patent Families and Patenting Strategies
SG188825 appears as part of a broader patent family, comprising filings across multiple jurisdictions—such as US, EP, and CN filings—aiming to secure global rights.
-
The filing strategy includes broad composition claims alongside method and formulation patents.
-
Some rivals may file design-around patents targeting specific aspects like delivery mechanisms to circumvent SG188825.
3. Patent Expiry and Obviousness Risks
The 2019 filing date indicates potential patent expiry around 2039, assuming 20-year patent terms, provided all maintenance fees are paid.
-
The strength of the claims around the core compound reduces risks of invalidation based on obviousness, although prior art related to similar chemical structures demands scrutiny.
-
Ongoing patent applications may introduce narrower claims or supplementary patents to extend protection or reinforce the core patent.
4. Competitive Patent Filings
Competitive landscape suggests multiple patents targeting similar chemical scaffolds and therapeutic applications, often targeting similar indications like cancer or infectious diseases.
-
The overlap emphasizes the importance of precise claim drafting to avoid overlap or invalidation.
-
Universities and biotech startups also contribute to the filament, often focusing on derivative compounds or novel delivery systems.
Legal and Patentability Considerations
-
Novelty: The compound’s unique structural features and specific substitutions confer novelty over prior art.
-
Inventive Step: The economic and clinical significance of the claimed improvements in efficacy or reduced side effects bolster inventive step assertions.
-
Industrial Applicability: The claims demonstrate clear utility in treating specific diseases, satisfying statutory requirements.
-
Potential Challenges: Prior art disclosures of similar compounds or methods must be examined for validity challenges, especially if structural similarities exist.
Implications for Stakeholders
-
Pharmaceutical Companies should evaluate freedom-to-operate by conducting detailed prior art searches to assess the scope of SG188825.
-
Patent Filers aiming for complementary or competing innovations must carefully draft narrower claims to avoid infringement or invalidation.
-
Investors can leverage the robustness of these patents as indicators of technological advantage and market exclusivity.
