What is the Scope of Patent WO2006115626?
Patent WO2006115626, assigned to a pharmaceutical applicant under the World Intellectual Property Organization (WIPO), covers a class of compounds and their pharmaceutical applications. Its scope encompasses:
- Specific chemical structures, primarily derivatives of a core scaffold, likely targeting therapeutic areas such as oncology, neurology, or infectious diseases.
- Methods of preparing these compounds.
- Pharmaceutical compositions containing the compounds.
- Medical uses of the compounds for treating particular indications.
The patent claims are structured to cover both the compounds themselves and their use in medicine, including methods of administration.
What Are the Main Claims of the Patent?
The patent's claims can be categorized as follows:
1. Compound Claims
- Cover specific chemical entities, characterized by certain substituents attached to the core structure.
- Typically, claims specify precise substitution patterns, such as alkyl, aryl, or heteroaryl groups, with scope extending to various derivatives within the defined structural formula.
2. Pharmaceutical Composition Claims
- Claim the inclusion of the compounds in pharmaceutical compositions for therapeutic purposes.
- Include formulations such as tablets, capsules, or injections.
3. Method of Use Claims
- Cover methods of administering the compounds to treat diseases, for example, cancer, viral infections, or neurological conditions.
- Claims specify the dosage, route of administration, and treatment regimen, sometimes focusing on particular patient populations.
4. Process Claims
- Describe processes of synthesizing the compounds, often including specific reaction conditions, catalysts, or intermediates.
Claim Breadth and Limitations
- The claims are broad with some dependents narrowing scope to specific derivatives.
- The core structural formula claims extend coverage to generic derivatives within the claimed chemical space.
- Auxiliary claims specify specific embodiments with improved pharmacological activity or selectivity.
