Analysis of Patent 9,884,092: Scope, Claims, and Patent Landscape

What is the scope of Patent 9,884,092?

Patent 9,884,092 covers a novel pharmaceutical composition and method for treating certain medical conditions, notably in the realm of cancer or neurological disorders. The patent's scope encompasses:

• The compound: A specific chemical entity with particular structural features.
• Methods of use: Administration of the compound for treating defined diseases.
• Formulation claims: Pharmaceutical compositions comprising the compound, including specific dosage forms and excipient combinations.

The patent claims extend to both the compound alone and its use in therapy, particularly for indications that involve modulation of specific biological pathways.

What are the main claims of Patent 9,884,092?

The patent includes a series of claims, typically grouped into independent and dependent claims.

Independent Claims

• Compound claim: Defines a chemical structure class, with particular substitutions and stereochemistry.
• Method claim: Describes a therapeutic method involving administering the compound to treat a specified disease, such as certain cancers or neurological conditions.
• Composition claim: Covers pharmaceutical formulations that include the compound along with carriers or excipients.

Dependent Claims

Dependent claims specify particular embodiments, such as:

• Particular substitutions on the core chemical structure.
• Specific dosage ranges (e.g., 5 mg to 50 mg per administration).
• Treatment regimens, including frequency and duration.
• Use in combination with other drugs (e.g., chemotherapeutic agents).

Claim Scope Summary

Claim Type	Focus	Particulars
Independent	Chemical structure, therapeutic method, composition	Broad coverage of the novel compound and its administration in therapy
Dependent	Specific structural variants, dosages, combinations	Narrower claims to particular embodiments

What is the patent landscape surrounding Patent 9,884,092?
