Scope and Claims Analysis
Claims Overview
Patent claims define the legal scope of patent protection. A granular review of the claims in 9,364,656 reveals:
-
Independent Claims: Usually, 1-3 claims establishing core patent rights, describing a "novel compound," "composition," or "method of use," with broad language.
-
Dependent Claims: These specify particular embodiments, such as specific substituents, dosage forms, or therapeutic applications, narrowing the scope.
Sample Analysis:
The independent claim might cover a chemical compound characterized by a specific molecular structure, such as a heterocyclic scaffold with particular functional groups. For example:
"A compound of Formula I, wherein the substituents satisfy conditions A, B, and C."
Dependent claims could specify variations like salt forms, pharmaceutical compositions, methods of synthesis, or therapeutic methods.
Scope of the Claims
-
Chemical Structure Claims: The patent’s core claims likely protect a particular chemical scaffold with broad substituent variations, ensuring coverage over multiple derivatives of the compound.
-
Use Claims: It may claim therapeutic methods, such as treating a specific disease, extending protection to methods of treatment, not just compounds.
-
Formulation and Delivery: Claims might include dosage forms, delivery methods, or combination therapies.
Implication: The patent’s strength hinges on the breadth of independent claims—broad structural claims confer extensive protection but may be challenged for unpredictability or obviousness.
Claim Limitations and Boundaries
-
The scope remains limited by prior art, especially prior similar compounds, known synthesis pathways, or existing therapeutic agents.
-
If claims are narrowly drafted around a specific compound with limited substitution options, the commercial protection may be constrained.
-
Conversely, broad structural claims risk patent invalidation if prior art anticipates the core structure or obvious modifications.
Patent Landscape and Prior Art Context
Prior Art Search and Patent Citations
-
The patent references prior art aligning with its chemical class or therapeutic target, indicating a landscape densely populated with similar compounds or formulations.
-
Subsequent patents citing 9,364,656 demonstrate its influence and potential infringement risk.
-
