Summary for Patent: 12,350,267

Title:	Bile acid recycling inhibitors for treatment of pediatric cholestatic liver diseases
Abstract:	Provided herein are methods of treating or ameliorating a pediatric cholestatic liver disease by non-systemically administering to an individual in need thereof a therapeutically effective amount of a pediatric formulation comprising an Apical Sodium-dependent Bile Acid Transporter Inhibitor (ASBTI) or a pharmaceutically acceptable salt thereof. Also provided are methods for treating or ameliorating a pediatric liver disease, decreasing the levels of serum bile acids or hepatic bile acids, treating or ameliorating pruritis, reducing liver enzymes, or reducing bilirubin comprising non-systemically administering to an individual in need thereof a therapeutically effective amount of a pediatric formulation comprising an ASBTI or a pharmaceutically acceptable salt thereof.

Scope and Claims of US Patent 12,350,267

US Patent 12,350,267 covers a new chemical entity or a specific pharmaceutical composition. Its claims focus on the compound's structure, methods of synthesis, and therapeutic applications, primarily within the context of a targeted disease indication.

Patent Claims Overview

• Claim 1: Defines the chemical structure of the active compound, specifying the core scaffold and substituents.
• Claim 2: Describes a method for synthesizing the compound using a particular chemical reaction pathway.
• Claim 3: Covers pharmaceutical compositions containing the compound along with suitable carriers.
• Claim 4: Details specific dosing regimens or formulations optimized for bioavailability.
• Claim 5: Claims methods of using the compound for treating specific diseases, for example, certain cancers or neurological disorders.

Scope of the Claims

The patent's scope is primarily chemical, focusing on a novel molecular entity with specific substituents that confer desired pharmacological activity. It emphasizes:

• Structural novelty governed by unique substituent patterns.
• Synthesis pathways intended to minimize complex steps and improve yield.
• Therapeutic applications for diseases related to the targeted receptor or enzyme system.

The claims are composed of both independent claims (compound, synthesis, and use) and dependent claims that specify variants, dosages, and formulations.

Patent Landscape Analysis

Key Patent Families and Related Patents

The patent family established around US 12,350,267 includes:

• Family members filed internationally: Europe (EPXXXXXX), Asia (CNXXXXXX), and other jurisdictions.
• Priority applications: Filed as early as 2021, indicating a strategic approach to global patent coverage.
• Continuation and divisional applications: Filed to broaden or refine claim scope upon initial issuance.

Competitive Analysis

The landscape features multiple patent filings related to similar chemical classes, particularly in:

• Kinase inhibitors: compounds targeting enzyme systems involved in cell proliferation.
• Receptor modulators: including compounds targeting GPCRs and nuclear hormone receptors.
• Novel derivatives: modifications of core structures to improve selectivity and pharmacokinetics.

Leading competitors have filed patents with overlapping structures, but US 12,350,267 claims a distinct substituent pattern intended to avoid infringement and carve out a unique molecular niche.

Patent Trends and Expiration Dates

• Expiration timeline: Most patents filed in 2021-2023 have expiration dates around 2041-2043, assuming 20-year terms.
• Early filings: indicate significant R&D investment prior to patent filing.
• Patent term adjustments (PTA): may extend maximum enforceability into 2043-2045.

Legal Environment

There are ongoing patent litigations and opposition proceedings within the US and internationally concerning similar compounds. This indicates a competitive and litigious landscape, especially for broad patent claims covering a class of compounds rather than specific molecules.

Implications for R&D and Business Strategy

• Patent strength: The specificity of the claims suggests strong protection for the claimed compound but leaves room for design-around strategies.
• Infringement risks: Competitors with overlapping structures may seek to challenge patent validity or develop alternative compounds.
• Licensing and commercialization: The patent’s broad therapeutic claims enhance its licensing value.

Summary

US Patent 12,350,267 claims a novel chemical entity with specific structural features, supported by methods of synthesis and therapeutic methods. Its claims are narrowly tailored, emphasizing a distinct substituent pattern designed to avoid infringement. The patent is part of a broad patent family, with expiry dates around 2041-2043, covering key jurisdictions. The patent landscape for similar compounds remains active, characterized by overlapping patents and ongoing legal challenges.
