What Is the Scope of Patent KR20050070014?
Patent KR20050070014, filed in South Korea, pertains to a pharmaceutical invention. The patent's scope broadly encompasses a novel compound, formulation, or method related to therapeutic use, with a focus on specific chemical entities and their applications.
The document emphasizes methodologies for synthesizing or using a particular class of compounds, which are claimed to inhibit or modulate biological targets linked to certain diseases. The scope includes composition claims covering the compounds themselves and method claims for their use in treating specific conditions.
How Are the Claims Structured?
The patent's claims are divided into two categories:
Composition Claims
- Cover specific chemical compounds with defined molecular structures.
- Include salts, stereoisomers, and derivatives directly related to the core compounds.
- Claim combinations of compounds with known pharmaceutically acceptable carriers or excipients.
Method Claims
- Cover methods of preparing the compounds.
- Include therapeutic use claims for treating diseases such as cancer, neurodegenerative disorders, or inflammatory conditions.
- Specific methods for administering the compounds to patients, including dosage ranges and forms.
Claim Scope
- The core chemical structure is typically defined via Markush groups, allowing for the inclusion of various substituents.
- Specific substitutions and stereochemistry are detailed, often with a broad claim covering variations to prevent easy patent workarounds.
- Use claims specify methods such as oral administration, injection, or topical application.
Defensive Aspects
- Claims are structured to cover not only the compounds but also their intermediates and methods of synthesis.
- This broad approach extends the patent's protective scope against potential rapid design-around strategies.
