Patent US 7,585,493: Scope, Claims, and Landscape
What Is the Scope of the Patent?
United States Patent 7,585,493 protects a specific formulation, method, or compound. The patent claims focus on a novel drug ingredient, formulation, or delivery system. The scope, as defined in the claims, explicitly covers the subject matter described therein.
The patent's primary focus is on a chemical composition or method for treating a medical condition. It typically covers:
- The active ingredient or a specific compound with defined chemical structure(s).
- An associated formulation including excipients, carriers, or delivery mechanisms.
- Treatment methods involving administration protocols or dosing regimens.
The scope extends to all uses, formulations, or embodiments that fall within the claims’ language, which limits the patent rights to the specific embodiments described and equivalents reasonably foreseeable.
What Are the Main Claims?
The claims define the legal boundaries. They are divided into independent and dependent claims.
Key independent claims generally cover:
- The chemical composition with particular molecular features.
- A method of use involving administration of the compound for specific indications.
- A dosage form or delivery system containing the compound.
Typical claim pattern:
| Claim Type |
Description |
Example (Hypothetical) |
| Independent |
Broad scope of compound or method |
"A pharmaceutical composition comprising a compound of formula I, wherein the compound has activity against [target disease]" |
| Dependent |
Specific embodiments, such as dosage, formulation, or application |
"The composition of claim 1, wherein the compound is administered in a 50 mg dose" |
In US patent 7,585,493, claims likely cover:
- The chemical structure of a novel drug or polymorph.
- Use of the compound in treating a disease.
- Formulations, such as controlled-release forms.
- Methods of manufacturing.
Typical claim language:
- Composition claims specify molecular formulae, stereochemistry, or substitution patterns.
- Method claims specify administration regime, e.g., "administering 20 to 50 mg daily."
- Delivery claims may include injections, oral tablets, or topical applications.
The breadth of the claims determines the patent's enforceability and commercial scope. Overly broad claims risk invalidation, while narrow claims limit market protection.
