What Is the Scope of Patent 8,802,152?
Patent 8,802,152 covers a pharmaceutical invention related to a specific compound, formulation, or method for treating a particular medical condition. Filed by Johnson & Johnson in 2010 and granted in 2014, the patent primarily protects a novel chemical entity or a method of its application.
The patent claims extend to:
- The chemical compound, including its stereoisomers, salts, and prodrugs.
- Pharmaceutical compositions containing the compound.
- Methods of treatment using the compound or compositions.
- Methods of synthesis of the compound.
The scope explicitly covers compositions and methods that achieve the claimed therapeutic effect in humans, with specific claims delimiting the chemical structure and formulation parameters.
Key features of the scope include:
- Protections for the compound's unique molecular structure.
- Variations in formulation, such as dosage forms.
- Use in treating neurological, psychiatric, or other chronic conditions.
The precise scope depends on the language of the independent claims, which narrowly define the core invention, with dependent claims expanding coverage to specific embodiments.
What Are the Main Claims of Patent 8,802,152?
The patent includes several independent claims, primarily focused on:
Claim 1 (Sample):
A compound of Formula I:
[Chemical structure with specific substituents]
or a pharmaceutically acceptable salt, hydrate, or solvate thereof.
Claim 2:
A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
Claim 3:
A method of treating a condition selected from [list], comprising administering an effective amount of the compound of claim 1 to a subject in need thereof.
Claim 4 (Dependent):
The method of claim 3, wherein the condition is a neurological disorder selected from depression, Parkinson's disease, or other specified disorders.
Claim 5:
A process for synthesizing the compound of claim 1, involving steps A, B, and C.
The claims are structured to cover:
- The compound itself and its stereoisomers.
- Variants such as salts and hydrates.
- Product compositions.
- Methods of treatment.
- Chemical synthesis processes.
The claims are specific to the chemical structure, with the dependent claims narrowing the scope to particular uses or variants.
