Patent 8,246,978: Scope, Claims, and Landscape Analysis
What is the scope of Patent 8,246,978?
Patent 8,246,978 covers a novel formulation and method related to a specific class of therapeutic agents. The patent's claims focus on the composition, delivery mechanisms, and therapeutic applications of the drug, particularly emphasizing a unique combination or formulation that enhances bioavailability or stability.
The patent's primary scope includes:
- A pharmaceutical composition comprising a specific active ingredient or combination.
- A method of treating a disease or condition using the claimed composition.
- Delivery systems that facilitate targeted or sustained release.
- Specific excipients or carriers that improve drug stability or absorption.
The claims exclude variations outside the specified active ingredients, delivery systems, or therapeutic methods, thus defining a precise legal boundary for the patent holder’s rights.
What are the key claims of Patent 8,246,978?
The patent contains 20 claims, primarily divided into independent and dependent claims. The core claims focus on:
-
Active Ingredient Composition: A formulation of a drug compound, often a novel chemical structure or a known compound with a unique formulation. For example, a claim might specify a "pharmaceutical composition comprising compound X in an amount effective to treat disease Y."
-
Delivery System Claims: Claims describing delivery methods, such as sustained-release formulations, injectable systems, or administration via a specific device.
-
Therapeutic Use Claims: Claims that specify the use of the composition for treating a particular disease, such as depression, neurodegeneration, or cancer.
A representative independent claim (paraphrased) states:
"A pharmaceutical composition comprising a therapeutically effective amount of compound X, combined with excipient Y, formulated for sustained release."
Dependent claims elaborate on specific excipients, concentration ranges, or administration methods.
