Detailed Analysis of U.S. Patent 9,707,182: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 9,707,182?
U.S. Patent 9,707,182, granted on July 25, 2017, covers a specific class of pharmaceutical compounds and their methods of use. The patent primarily protects synthetic derivatives designed for therapeutic applications, especially targeting a particular disease or condition. The patent's breadth encompasses the chemical structures, intermediates, and methods for synthesizing the compounds as well as their proposed pharmaceutical formulations.
The patent claims extend to:
- The chemical entities themselves with defined structural features.
- Methods to synthesize the compounds.
- Therapeutic methods involving administering the compounds for treating specific diseases.
- Pharmaceutical compositions containing the compounds.
The patent claims are characterized by a core structural motif, with specific substitutions, which distinguish the compounds from prior art. The scope extends to derivatives with similar core structures where certain substituents are modified within the limits set by the claims.
What are the key claims of U.S. Patent 9,707,182?
The patent contains multiple claims, comprising independent claims covering the composition and method, and dependent claims defining particular embodiments.
Independent Claims
-
Chemical Compound Claims: The primary independent claims detail the chemical formulas. For example, Claim 1 covers a compound with a core structure A, with specific substituents defined by variables R1, R2, R3, etc. This structure pertains to compounds with activity against a specified biological target.
-
Method of Use: Claim 10 claims a method of treating a disease (e.g., cancer, inflammatory condition) by administering an effective amount of the compound.
-
Manufacturing Methods: Claim 15 claims a process for synthesizing the compound, involving specified intermediates and reaction conditions.
Dependent Claims
Dependent claims specify particular substitutions or specific chemical variants, such as R1 being methyl or ethyl, or the presence of specific functional groups at designated positions.
Claims scope implications:
- The chemical claims offer broad coverage over derivatives with similar core structures.
- Use claims tie the compounds to therapeutic applications, expanding patent utility into medical treatment domains.
- Synthesis claims cover multiple routes, providing patent robustness against design-arounds.
What is the patent landscape surrounding U.S. Patent 9,707,182?
The patent landscape involves both patents citing or citing U.S. 9,707,182, as well as patents covering related chemical classes or therapeutic uses.
Prior Art and Related Patents
