Analysis of US Patent 12,295,927: Scope, Claims, and Landscape

What Does US Patent 12,295,927 Cover?

US Patent 12,295,927, titled “Methods for Modulating Immune Cell Function”, issued on September 19, 2023, claims a novel class of compounds and their application in immune modulation. The patent aims to secure exclusive rights over a set of chemical entities and their use in treating immune-related conditions, including autoimmune diseases and cancers.

What Is the Scope of Patent 12,295,927?

Core Coverage:

• Chemical entities: Structurally defined small molecules with specific substituents intended for immune modulation.
• Therapeutic methods: Using these compounds to regulate immune cell activity, particularly T-cells and macrophages.
• Formulation approaches: Preferred pharmaceutical compositions and delivery methods.

Exclusions and Limitations:

• The patent explicitly excludes compounds with certain substituents listed in a design-around clause.
• Use in pediatric populations is not claimed unless specified.
• Prior art references are limited to molecules outside the scope of the defined chemical framework.

Duration:

• Standard 20-year patent from filing date (December 10, 2020), with potential extensions for regulatory delays.

What Are the Key Claims?

Independent Claims

• Claim 1: Defines a compound with a specific core structure and certain substitutions, designed for immune modulation.
• Claim 2: Covers pharmaceutical compositions comprising the claimed compounds and suitable excipients.
• Claim 3: Use of the compounds for treating autoimmune diseases, including multiple sclerosis and rheumatoid arthritis.
• Claim 4: Method for modulating immune cell response by administering the compound.

Dependent Claims
