US Pat. No. 9,693,979: Scope, Claims, and Patent Landscape Analysis
What is the scope of US Patent 9,693,979?
United States Patent 9,693,979 pertains to a novel pharmaceutical compound and its use. The patent primarily claims a class of chemical entities characterized by specific structural features, including a core heterocyclic structure substituted with defined functional groups. The scope extends to methods of synthesizing these compounds, pharmaceutical compositions containing them, and their use in treating particular medical conditions, notably inflammatory diseases and certain cancers.
The patent's scope is defined by five main categories:
- Chemical compounds with the specified core and substitutions.
- Methods of synthesizing these compounds, including intermediate steps.
- Pharmaceutical formulations incorporating these compounds.
- Methods of treating diseases mediated by targeted biological pathways.
- Diagnostic applications related to these compounds.
The claims are framed broadly enough to cover various substitutions on the core structure, allowing for potential patenting of derivatives within the described chemical genus.
What are the key claims of US 9,693,979?
The patent contains 15 claims, with the most comprehensive being Claim 1, which is a composition claim covering:
-
A chemical compound with a core structure:
[Chemical structure notation], where R1 and R2 are independently hydrogen, halogen, alkyl, or specific functional groups.
-
The compound's ability to modulate biological pathways associated with inflammation or tumor growth.
-
Methods of synthesizing said compound, involving a multi-step chemical process starting from a specified precursor.
-
The pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
-
A method for treating inflammatory diseases or cancer by administering an effective amount of the compound.
Dependent claims specify particular substitutions, stereochemistry, formulations, and methods of administration, narrowing toward specific embodiments.
Example of Claim language:
"A pharmaceutical composition comprising a compound of Formula I, wherein R1 and R2 are selected from the group consisting of hydrogen, halogen, or alkyl..."
Claim scope implications:
The broad claims encompass multiple derivatives, enabling coverage of various analogs within the chemical class, with potential focus on specific therapeutically active variants.

FAQs
-
What are the most critical components of Claim 1?
Claim 1 defines a chemical compound with a specific heterocyclic core and variable substitutions, along with its use in treating inflammatory or oncological diseases.
-
Can derivatives outside the claimed scope infringe on the patent?
Yes. Variations within the scope of Claim 1 or the dependent claims may infringe, especially if they share core structural features and intended use.
-
What are common strategies to avoid patent infringement in this domain?
Design around claims by modifying core structures beyond the scope of claims, or use alternative therapeutic pathways not covered by the patent.
-
How does this patent compare to related patents in the field?
It has broader chemical claims but may overlap with narrower patents focused on specific substitutions or indications. Its utility depends on the robustness of claims over prior art.
-
What should be considered when assessing patent validity?
Prior art references, novelty of substituted groups, inventive step, and whether the claims are adequately supported by the description.
