What is the Scope of Patent CA2887379?
Patent CA2887379 covers a specific pharmaceutical compound or formulation, with an emphasis on its use in treating a designated condition. The patent claims encompass chemical entities, methods of manufacturing, and therapeutic applications.
Based on public patent databases, the patent's key scope includes:
- A pharmaceutical composition comprising a specific compound or its pharmaceutically acceptable salts.
- Use of the compound for treating a designated disease or condition.
- Methods for preparing the compound.
Claims extend to dosage forms, specific formulations, and delivery mechanisms, including sustained-release or targeted delivery systems.
What Are the Key Claims of the Patent?
The patent's claims are divided into independent and dependent claims. The primary independent claims typically establish the core invention.
Core Claims
- Chemical Entity: The claims cover a novel chemical compound with specific structural features, including substitutions at certain positions on the core molecule.
- Therapeutic Use: The patent claims the use of the compound in treating a specific indication, such as a neurological disorder or infectious disease.
- Manufacturing Method: Claims relate to a controlled process of synthesizing the compound, emphasizing steps like purification or specific reaction conditions.
Dependent Claims
Dependent claims specify variations, such as:
- Specific salts or polymorphs of the compound.
- Alternative formulations, such as oral tablets or injectables.
- Combinations with other therapeutic agents.
Claim Breadth and Limitations
The claims are broad enough to include various salts and formulations, but narrow regarding the exact chemical structure, with specific substitutions defining the scope. The use of Markush structures suggests potential coverage of a class of compounds rather than a single molecule.
