United States Patent 8,470,364: Scope, Claims, and Patent Landscape
What Is the Scope of Patent 8,470,364?
Patent 8,470,364 covers a pharmaceutical compound, its pharmaceutical compositions, and methods of use. The patent aims at protecting a specific class of molecules targeting a particular biological pathway, primarily for therapeutic applications.
Key features of the scope:
- The invention encompasses certain chemical structures, including specific substitutions on core molecular frameworks.
- It claims methods of administering the compounds for treating diseases, likely involving specific indications such as inflammatory or oncological conditions.
- The patent covers pharmaceutical compositions containing the compounds, including formulation specifics.
How Broad Are the Claims?
Patent claims define the legal boundaries. Patent 8,470,364 contains a combination of independent and dependent claims:
Independent Claims:
- Claim 1: Covers a compound of a particular chemical formula with defined substituents, emphasizing chemical structure and functional groups.
- Claim 15: Claims a method of treating a disease involving administering the compound of Claim 1.
- Claim 20: Focuses on pharmaceutical compositions comprising the compound.
Dependent Claims:
- Narrow the scope by specifying variations of substituents, dosage forms, or treatment regimens.
- Example: Claims specify particular substitutions at certain sites (e.g., Claim 2 may specify a methyl group at a defined position).
Scope Analysis:
- The independent claims emphasize the core chemical structure, providing a reasonably broad protection for compounds falling within the specified chemical class.
- The method claim (Claim 15) indicates the targeted therapeutic application, limiting to certain disease states.
- Composition claims (Claim 20) ensure protection for formulations, including dosages and excipients.
