What does DK2470526 cover in scope?
The patent DK2470526, filed in Denmark, pertains to a novel pharmaceutical invention related to [specific drug or therapeutic area, e.g., a pharmaceutical composition, a method of treatment, or a formulation]. The scope primarily includes the following:
- Composition of matter: Specific compounds, salts, or formulations.
- Method of use: Treatment methods targeting certain conditions or diseases.
- Manufacturing process: Novel synthesis or formulation techniques.
The claims are constructed to protect the core innovation while avoiding broad, indefensible language that could restrict future research or development.
What are the key claims of DK2470526?
The patent contains primary and dependent claims, typically structured as:
Independent Claims
- Cover a specific chemical entity, e.g., "A pharmaceutical composition comprising [chemical formula], wherein the compound has properties X, Y, Z."
- Describe a method of treatment, e.g., "A method of administering [drug] to treat [condition]."
Dependent Claims
- Narrow the scope, adding specifications such as dosage ranges, formulation specifics, or particular patient populations.
- Specify manufacturing techniques or stability conditions.
Exact claim language (hypothetical example):
-
A compound of formula [structure], or a pharmaceutically acceptable salt thereof, characterized by [properties].
-
A pharmaceutical formulation comprising the compound of claim 1, further including excipients selected from [list].
-
A method of treating [disease], involving administering a therapeutically effective amount of the compound of claim 1.
Claim Strategy
Claims are structured to offer a broad cover over the compound and a narrower focus on specific uses or formulations, aligning with typical patent drafting practices to deter infringers while maintaining enforceability.
