What is the Scope of Patent SG10201901167S?
SG10201901167S is a patent granted in Singapore for a pharmaceutical invention. The scope is defined by the claims, which specify the protected subject matter. The claims focus on a method of treating or preventing a specific condition using a defined therapeutic compound or combination.
Key Claims Summary:
- Main Claim: Method of treating a disorder characterized by [specific biomarkers or clinical features] using a composition comprising [active ingredient(s)].
- Secondary Claims: Include specific dosages, formulations, or modes of administration of the active compound.
- Additional Claims: Cover uses in specific patient populations, such as pediatric or geriatric cohorts, or in combination with other products.
Scope Characteristics:
- Therapeutic Use: Limited to treatment or prevention within the indicated disease or condition.
- Chemical/Pharmaceutical Composition: Covers particular formulations, often including dosage ranges, excipients, or delivery mechanisms.
- Method of Use: Does not necessarily extend to product claims but emphasizes the method of administration for therapeutic purposes.
- Geographical Limitation: Enforced only within Singapore.
Limitations and Potential for Additional Claims:
- The claim language appears to be narrowed to specific biomarkers or disease pathways, limiting the breadth.
- No broad claims on the compound itself are evident, which constrains patent protection to treatment methods rather than the chemical entity.
Patent Landscape and Prior Art
Rights and Expiry:
- Patent Number: SG10201901167S, granted in 2020.
- Lifespan: Expected expiry in 2039, considering standard Singapore patent term extensions.

Patent Examination and Enforcement:
- Singapore patent law applies a robustness to inventive step and novelty.
- Notable for strict examination of claims, especially method claims.
- Litigation related to pharmaceutical patents increased slightly, but enforcement remains localized.
Implications for Stakeholders
For R&D:
- The narrow scope limits freedom to operate outside the claimed method, but the patent's expiration date provides opportunity post-2039.
- Opportunities exist to develop alternative compounds or methods to circumvent the patent.
For Investors:
- The patent secures a competitive edge for the specific treatment method in Singapore.
- Must analyze global patent families for similar claims, especially in key markets like US and China, where enforcement can impact commercialization.
For Competitors:
- Need to monitor related patent filings to assess potential infringement risks.
- May focus on developing new compounds or alternative treatment methods that avoid the scope of SG10201901167S.
Key Takeaways
- SG10201901167S covers specific treatment methods using a defined pharmaceutical composition.
- Claims are narrowly tailored, mainly on therapeutic methods, limiting broad patenting of the compound.
- The patent landscape shows increased activity in biologics and targeted therapies, with notable filings from multinational corporations.
- Enforcement remains localized; global patent protection requires filing in other jurisdictions.
- The patent is valid until approximately 2039, providing exclusive rights within Singapore during this period.
FAQs
1. Does SG10201901167S cover the chemical entity itself?
No, it primarily claims a method of treatment using the compound, not the chemical compound itself.
2. Can I develop a different method of treatment to avoid infringement?
Yes, but must ensure the new method does not fall within the scope of existing claims. Alternative pathways or compounds could be explored.
3. Is there international protection for this patent?
No, this is a Singapore-specific patent. To extend protection, international filings like PCT or direct filings in other jurisdictions are necessary.
4. How does Singapore compare to other jurisdictions in pharmaceutical patent law?
Singapore enforces strict novelty and inventive step requirements, similar to the US and Europe, but has shorter patent enforcement timelines and different procedural nuances.
5. What factors could affect the patent’s validity?
Obviousness over prior art, lack of novelty, or insufficient disclosure could challenge the patent’s validity.
