What is the Scope of Patent SG11201503637S?
SG11201503637S covers a pharmaceutical composition or method related to a specific drug. The patent's scope is primarily defined by its independent claims, which outline the core inventive features. This patent appears to focus on a novel formulation, production process, or therapeutic use related to a particular active ingredient or combination.
The patent encompasses:
- An active pharmaceutical ingredient or combination thereof
- A specific formulation or preparation method
- Application to a particular medical condition or treatment regime
The scope excludes prior art that does not meet the specific combination of features outlined in the claims. It also likely emphasizes novel aspects over existing formulations or methods.
What Are the Key Claims?
The claims delineate the boundaries of protection. The patent includes:
- Independent Claims: Usually define the primary inventive aspect, such as a unique chemical compound, formulation, or method of administration.
- Dependent Claims: Specify particular embodiments, such as dosage, delivery system, or specific therapeutic applications.
Given typical patent structure, claims may include:
- A pharmaceutical composition comprising a compound X in a specified form.
- A method of treating condition Y by administering the composition.
- A manufacturing process for the composition with particular steps.
The core inventive claim likely emphasizes the novelty of the formulation method or compound combination that provides unexpected therapeutic benefits or improved stability.
How Does the Claim Set Compare to Similar Patents?
Compared to similar patents, SG11201503637S likely:
- Has narrower scope if it focuses on a specific compound or formulation
- Is broader if it covers a class of compounds or multiple application methods
- Is aligned with patents from major pharmaceutical filings in Singapore, which often emphasize incremental innovations
It probably shares claim language with international patents filed via PCT routes, especially if the applicant seeks to extend protection beyond Singapore.
