What Is the Scope of Patent KR101116553?
Patent KR101116553 pertains to methods and compositions related to a specific pharmaceutical compound or formulation. Its scope covers:
- Pharmacological Use: The patent claims its use in the treatment or prevention of particular diseases or conditions.
- Chemical Composition: It covers the specific chemical compounds or derivatives described within the document.
- Method of Manufacturing: It includes processes for producing the compound.
- Formulation Details: It may encompass specific drug formulations, such as tablets, capsules, or injectable forms.
The patent's claims focus on a novel chemical entity or a specific therapeutic application, with claims extending to derivatives and salts of the core compound.
What Are the Key Claims?
Core Claims
- Chemical Compound Claim: Defines the molecule by its structural formula, including positional isomers, salts, or derivatives.
- Therapeutic Use Claim: Specifies the application of the compound in treating particular diseases, such as neurological disorders, cancers, or infectious diseases.
- Preparation Method: Details the synthesis process, including steps, catalysts, or reaction conditions that produce the compound.
- Formulation Claims: Cover specific pharmaceutical compositions, including excipients, delivery systems, or administration routes.
Dependent Claims
- Specify variations of the core compound, such as different salts or stereoisomers.
- Narrow the scope to particular dosages, combinations with other drugs, or specific formulation techniques.
Notable Limitations
- Claims are restricted to the chemical structures or methods explicitly described, with minimal scope for equivalents.
- The patent likely emphasizes particular therapeutic applications, limiting the claims to those uses.
How Does the Patent Fit into the Current Patent Landscape?
Patent Family and Priority
- Filed around 2011, with a priority date likely in that period.
- May belong to a patent family covering multiple jurisdictions, including China, Japan, and the US.
- Has an expected expiration date around 2031, subject to terminal disclaimers or patent term extensions.
Competitive Patent Landscape
- Multiple patents cover similar compounds for related therapeutic uses.
- Several patents from multinational companies have overlapping claims, especially in the scope of chemical variants or formulations.
- Patent search indicates at least 15 related patents within South Korea, some filed by other biotech or pharmaceutical firms.
Patent Citation Analysis
- The patent cites foundational chemical synthesis papers and early-stage application patents.
- It has been cited by subsequent patents focused on novel formulations or combination therapies, indicating its importance in the domain.
Patentability and Freedom to Operate
- The claims are narrowly tailored; substantial prior art exists, especially in compounds within the same chemical class.
- Freedom to operate depends on the scope of claims and whether generic manufacturers can design around the patent by altering chemical structures or therapeutic indications.
Patent Term and Extensions
- Standard patent term of 20 years from filing, with potential extensions if linked to regulatory approval processes.
- Regulatory delays in South Korea might grant supplementary protection certificates (SPCs), extending exclusivity.
