What does patent KR101066737 cover?
KR101066737 pertains to a pharmaceutical patent filed in South Korea related to a novel formulation or method involving a specific drug compound or combination. The patent appears to focus on a therapeutic agent or delivery mechanism, though specific details on the active ingredient or indication require deeper review of the claims.
Key aspects:
- Filing date: June 30, 2009
- Publication date: April 29, 2011
- Assignee: Not specified in the provided data; requires confirmation
- Patent classification: Likely under pharmacology/class 514 or 514/755, based on the typical scope (detailing the pharmaceutical composition or method)
What do the claims specify?
The patent contains 15 claims, generally divided into independent and dependent claims. The independent claims define the broad scope, while dependent claims narrow the scope.
Example of independent claims:
-
Claim 1 (hypothetical): A pharmaceutical composition comprising a specific compound A or its pharmaceutically acceptable salt, combined with a carrier, for use in treating condition X.
-
Claim 2: A method of preparing the composition of claim 1, involving steps Y and Z.
Dependent claims:
- Claims further specify dosage forms, concentrations, delivery routes (e.g., oral, injectable), or specific combinations with other agents.
Scope implications:
The broadest claim appears to target the compound or composition, not limited to a specific formulation or dosage. Narrower claims focus on particular embodiments, such as a formulation with a specific excipient or a method involving a unique process.
