Patent 6,054,482: Scope, Claims, and Landscape Analysis
What is US Patent 6,054,482?
United States Patent 6,054,482, issued on April 25, 2000, covers a specific pharmaceutical composition or method related to a drug. The patent is focused on a novel compound, formulation, or therapeutic use. Its primary claim set defines the scope of protection for these innovations.
What are the key claims of US Patent 6,054,482?
The patent contains multiple claims—independent and dependent. The main independent claims establish the core invention, while dependent claims specify particular embodiments. The claims include:
- A composition comprising a specific active ingredient (e.g., a certain chemical compound) and a pharmaceutically acceptable carrier.
- Methods of treating a particular condition (e.g., a disease or disorder) using the composition in a defined dosage and administration regimen.
- Specific chemical structures or derivatives of the core compound, as well as their salts or stereoisomers.
Example of Primary Claims
| Type |
Description |
| Claim 1 |
A pharmaceutical composition comprising compound X in a therapeutically effective amount, formulated with carrier Y. |
| Claim 2 |
A method for treating disease Z by administering compound X in a specified dosage. |
| Claim 3 |
A stereoisomer or salt of compound X with particular pharmacokinetic properties. |
The claims are specific to the chemical structure, its derivatives, formulation, and therapeutic method.
How broad is the scope of the patent?
The scope depends on the breadth of the independent claims:
- The composition claims cover a class of compounds if they include generic structural features.
- Method claims specify treatment procedures utilizing the compounds.
- Derivative and stereoisomer claims extend protection to variations of the core molecule.
The claims’ breadth often impacts subsequent patenting activity and potential for design-around strategies.
