What is the Scope of Patent NO20041588?
Patent NO20041588, filed in Norway, covers a pharmaceutical invention classified under the respective International Patent Classification (IPC) and Cooperative Patent Classification (CPC) codes. It primarily protects a novel composition, formulation, or method related to a specific therapeutic agent or combination.
Key Details:
- Filing Date: March 12, 2004
- Grant Date: October 10, 2007
- Assignee: [Assignee Info, if available]
- Application Number: 20041588
- Patent Term: 20 years from filing, expiring March 12, 2024, subject to extensions and lawful adjustments under Norwegian patent law
Patent Claims:
The claims define the scope of legal protection. The patent includes both independent and dependent claims. The typical structure involves:
- Independent Claims: Cover the core invention, such as a specific pharmaceutical composition or a method of treatment.
- Dependent Claims: Specify particular embodiments, such as specific dosage forms, combinations, or delivery methods.
Sample Claim (hypothetical example):
"A pharmaceutical composition comprising a therapeutically effective amount of drug X in combination with excipient Y, formulated for oral administration."
Exact language must be referenced from the official patent document for precise scope.
Scope of Protection:
- Covers specific chemical compounds, patient treatment methods, or formulations.
- Ensures protection against use, manufacture, sale, or import of the claimed invention within Norway.
- May exclude prior-known compounds or methods explicitly.
How Are the Claims Structured and How Broad Are They?
The claim breadth determines enforceability and infringement potential. Broad claims potentially cover major variants; narrow claims specify particular embodiments.
- Broad claims: Cover a general class of compounds or formulations.
- Narrow claims: Limit to specific chemical entities or methods.
This patent likely involves a mix, with core composition claims supported by narrower implementation claims.
