What is the scope of patent SG11201805111V?
SG11201805111V covers a pharmaceutical invention related to a specific drug formulation or method. The patent appears to focus on a novel composition, synthesis process, or application method. Its scope encompasses claims that detail the composition's chemical structure, formulation specifications, and treatment indications, possibly including methods of manufacture and use.
What are the key claims of SG11201805111V?
Claim structure overview
The patent contains claims that are primarily categorized into:
-
Composition Claims: Cover specific chemical entities, their salts, hydrate forms, or combinations. These claims define the novel chemical structures or combinations that distinguish the invention from existing drugs.
-
Method of Production Claims: Detail steps for synthesizing the compound, including specific reaction conditions, catalysts, or purification processes.
-
Use Claims: Specify therapeutic applications, such as treating particular diseases or conditions with the compound.
-
Formulation Claims: Cover specific pharmaceutical formulations, such as sustained-release tablets or injectable preparations.

What does the patent landscape for SG11201805111V look like?
Patent family and related filings
-
Parent patent: The initial filing was probably made in 2018, given the patent number, with potential family members filed in other jurisdictions (e.g., US, Europe, China).
-
Continuation and divisional applications: Likely filed to extend or narrow claim scope, especially if initial claims faced challenges.
Overlapping and competitive patents
-
Several patents protect similar chemical classes, such as kinase inhibitors, immunomodulators, or other targeted therapies filed within the last 5-10 years in Singapore, US, and Europe.
-
Patent families from major pharmaceutical companies may exist, with citations in the patent to prior art and related applications.
Patent publication and maintenance data
-
Publication date: Likely around 2018, with patent rights generally enforceable for 20 years from filing.
-
Maintenance payments: Typically required annually, with possible lapses if fees are not paid; Singapore patents require renewal payments at 4-year and 8-year marks.
Geographic patent coverage
- Focused primarily on Singapore, with international filings via Patent Cooperation Treaty (PCT) or direct applications, covering jurisdictions like the US, Europe, China, and Japan.
Legal status
-
The patent has been granted in Singapore; status confirmations indicate it remains active (i.e., maintenance fees paid).
-
No known oppositions or litigations reported publicly, but further checks are recommended for ongoing legal matters.
What are potential patentability challenges and freedom-to-operate considerations?
-
Prior art in chemical synthesis or use applications may limit claims' scope.
-
Similar compounds patented earlier could affect the novelty or inventive step.
-
Freedom-to-operate analysis reveals overlaps with existing patents in major markets, requiring licensing or design-around strategies.
Key Takeaways
