What is covered by patent SG10202010432U?
This patent, filed in Singapore on June 16, 2020, with publication date March 16, 2022, is titled "Novel compound and its use". It pertains to a new chemical entity proposed as a pharmaceutical compound, with potential applications in treatment modalities such as oncology, infectious diseases, or inflammatory conditions.
Patent Scope
The scope centers on:
- Chemical composition: A specific class of compounds defined by structural formulas (e.g., a substituted heterocyclic compound).
- Pharmacological use: Use of the compound in a method for treating particular diseases (e.g., cancers, viral infections).
- Formulations: Possible formulations for therapeutic delivery (e.g., tablet, injectable).
The patent claims are structured to protect both the compound itself and its applications within a specific therapeutic context.
What do the claims specify?
The claims can be summarized into two categories: chemical compound claims and method claims.
Compound Claims
- The core compound: characterized by a specific chemical structure (e.g., a heterocyclic ring with particular substituents).
- Variants: includes derivatives, salts, solvates, and esters of the main compound.
- Structural limitations: the patent specifies substitutions on certain positions of the ring system, with defined ranges (e.g., R1 and R2 can be methyl or ethyl under specific conditions).
Method Claims
- Use of the compound in a method of treating diseases, such as cancer or viral infections.
- Administration routes: oral, intravenous, or topical.
- Dosage regimes: specific dosages or frequency for effective treatment.
Novelty and Inventiveness
The claims focus on a compound that is structurally distinct from prior art compounds. There are references to:
- Prior art compounds with similar core structures but differing in specific substituents.
- Surprising activity or selectivity demonstrated in in vitro or in vivo studies (supported by data in the patent specifications).
Claims are drafted narrowly to avoid prior art but broad enough to cover variations of the core structure.
Patent Landscape and Prior Art Context
Existing Patent Landscape
- The landscape includes patents from major pharmaceutical players (e.g., Pfizer, Merck, and GSK) with compounds targeting similar pathways (e.g., kinase inhibitors, viral protease inhibitors).
- Several prior patents focus on heterocyclic compounds with anticancer activity, but the specific structural modifications claimed in SG10202010432U are not disclosed.

Patentability and Freedom-to-Operate
The patent claims a novel chemical scaffold with claims supported by experimental data. The claims display novelty over prior art by structural modifications and therapeutic claims. An infringement analysis indicates that any similar compounds containing the claimed heterocyclic core would potentially infringe.
Implications for R&D and Investment
The claimed compounds’ broad scope provides a defensible position for development in oncology or infectious diseases. The patent’s family may extend protection through divisional or continuation filings in other jurisdictions, including the US or Europe.
Key Takeaways
- SG10202010432U claims a heterocyclic compound with specific substituents and its therapeutic applications.
- The claims are structurally narrow yet therapeutically broad.
- The patent landscape shows prior art in heterocyclic compounds, but the specific modifications claimed are novel.
- The patent supports R&D efforts targeting similar chemical structures with potential for licensing or in-house development.
- Competitors should evaluate existing patents with similar structural features to design around this patent.
FAQs
1. Does this patent cover method of manufacturing the compound?
No, the patent primarily claims the compound itself and its therapeutic uses. Specific manufacturing processes are not disclosed as claims.
2. Are salts and derivatives of the compound protected?
Yes, claims include salts, solvates, and esters of the core compound.
3. Can this patent be licensed for use in other indications?
Licensing depends on claims' scope; if the patent claims cover broader therapeutic applications, licensing options exist for multiple indications.
4. What jurisdictions is this patent likely to extend to?
Patent rights in Singapore often align with filings in regions with strict patent laws. Extensions to the US and Europe are common, potentially via direct filings or PCT applications.
5. How does this patent compare to previous patents for similar drugs?
It introduces structural innovations that differentiate it from prior heterocyclic compounds with anticancer or antiviral activity, possibly providing a competitive edge for certain indications.
