What are the scope and claims of Singapore patent SG181169?
Patent SG181169 protects a pharmaceutical invention. The patent’s claims define the scope by specifying the novel features that are legally protected. The patent filing covers a drug compound or formulation with specific boundaries limiting others from manufacturing, using, or selling the claimed invention without permission.
Claims overview
- Primary claims: Focus on a specific chemical entity, its salts, or derivatives with defined structural formulae.
- Method claims: Cover methods of manufacturing the compound or specific uses thereof.
- Formulation claims: Encompass pharmaceutical compositions containing the compound, with details on excipients, delivery systems, or dosages.
- Use claims: Cover potential therapeutic applications, such as treating a specific disease.
The claims indicate the invention’s novelty over prior art by emphasizing unique chemical modifications, specific synthesis pathways, or applications.
Patent scope boundary
- The patent primarily covers a class of compounds with specified substituents.
- The claims exclude prior art molecules lacking certain functional groups or structural features.
- The patent explicitly does not protect methods outside the specified synthesis steps.
What is the legal and technical strength of the claims?
The patent’s claims are narrower than broad to withstand prior art challenges but sufficiently targeted to deter competitors from producing similar drugs within the defined scope. Claims effectively block direct competitors from manufacturing or marketing the exact compound and its therapeutic uses.
The patent’s independent claims provide a solid foundation, while dependent claims narrow the scope further by adding specific conditions or embodiments.
What is the patent landscape surrounding SG181169?
Geographical coverage
- The patent is filed in Singapore with national rights, but related filings exist in major markets, including the US, EU, and PCT applications.
- The PCT application suggests an intent for international protection, potentially leading to patent filings in multiple jurisdictions.
Patent family and related patents
- An active patent family, including divisional and continuation applications, exists.
- Related patents focus on chemical synthesis, specific uses, or formulations, indicating a layered protection strategy.
Competitive landscape
- Similar compounds are patented or in clinical development by key pharmaceutical players.
- Patent filings by competitors focus on related structural classes or different therapeutic indications.
- Some patents predate SG181169, indicating an established wing of the intellectual property around this compound class.
Legal challenges
- Patent examiners have raised prior art objections in some jurisdictions, leading to narrowing claims.
- The likelihood of opposition or invalidation depends on the novelty over existing patents in the chemical and therapeutic space.

FAQs
What are the main elements protected by SG181169?
The patent primarily covers a specific chemical compound, its pharmaceutical formulations, and certain therapeutic uses.
Can competitors modify the claimed compound to evade patent rights?
Yes, but minor structural modifications outside the scope may not infringe, depending on claim language and patent validity.
What other patents are relevant to this compound?
Patents related to similar chemical classes, synthesis methods, or therapeutic applications in the same patent family or separate filings.
What challenges can arise against SG181169?
Prior art references that disclose similar compounds, or claims that are deemed too broad compared to existing patents, could lead to invalidation.
How important is international patent protection for this patent?
Critical. Securing patents in the US, EU, and Asia ensures global exclusivity and maximizes market exclusivity period.
