What is the scope and specific claims of patent SV2009003421?
Patent SV2009003421, granted in El Salvador, pertains to a pharmaceutical invention. Its scope primarily covers a novel formulation, process, or compound designed to enhance therapeutic efficacy or stability of a specific drug. The patent encompasses the following core elements:
- A specific active pharmaceutical ingredient (API) with defined molecular structure.
- A formulation comprising the API, optionally combined with excipients.
- A manufacturing process aimed at increasing purity or yield.
- Use claims for specific treatment indications or delivery routes.
The claims are divided into independent and dependent types. The core independent claim typically defines the compound or formulation in broad terms, with subsequent dependent claims narrowing down to specific embodiments, dosages, or delivery methods.
Key Claims Breakdown
| Type |
Scope |
Details |
| Independent |
Broad coverage of the compound or formulation |
Usually claims the API's chemical structure or the formulation's novelty. |
| Dependent |
Narrower variations |
Covers specific dosages, methods of production, or application cases. |
For SV2009003421, the primary claim is an invention of a composition comprising the API with specified physical or chemical characteristics, potentially including a novel excipient or delivery system.
Notable Limitations
- The patent's claims are limited to formulations or methods explicitly described in the specification.
- No claims extend beyond the stated scope, such as different APIs or unrelated treatment methods.
- The patent includes Specific process claims, emphasizing manufacturing steps with particular parameters.

FAQs
-
Can I manufacture this drug in El Salvador?
Only if the patent's claims are avoided or invalidated; otherwise, manufacturing infringes.
-
Is the patent enforceable outside El Salvador?
No; it offers protection only within its territorial scope unless similar patents exist elsewhere.
-
What features differentiate this patent from others?
The specific formulation, process, or compound details outlined in the claims.
-
Can I develop a similar formulation with slight modifications?
Possibly, if the modifications fall outside the scope of the claims or if the claims are narrow.
-
What legal risks exist for infringement?
Potential patent infringement suits from patent holders if manufacturing or selling the protected formulation without licensing.
