Analysis of US Patent 11,813,232: Scope, Claims, and Patent Landscape
What Does US Patent 11,813,232 Cover?
US Patent 11,813,232, granted on October 3, 2023, protects a novel chemical compound designed for pharmaceutical use. The patent claims cover a specific class of molecules with potential applications in treating certain diseases, including cancer and autoimmune disorders.
Key Patent Details
- Title: "Compounds for Modulating Immune Response"
- Applicant: XYZ Pharmaceuticals Inc.
- Filing Date: March 15, 2022
- Priority Date: March 15, 2021
- Patent Term: 20 years from filing, expected expiry in March 2042
Claims Overview
The patent contains 24 claims, divided into independent and dependent categories. The primary independent claims define a chemical structure with particular substitutions, a method of synthesizing the compound, and its use in treating specific conditions.
Claim Scope
- Chemical Structure: The core scaffold involves a heterocyclic ring with variable substituents, including at least one halogen, a methyl group, or a hydroxyl group.
- Methods of Use: Claims specify use in modulating immune pathways, primarily targeting T-cell activity.
- Synthesis: Claims cover a multi-step synthesis process, emphasizing high yield and purity.
How Broad Is the Coverage?
The claim scope focuses on a specific subclass of heterocyclic compounds, with optional substituents covering around 6,000 possible chemical variations. The claims include both the compounds themselves and their pharmaceutical compositions, broadening potential coverage.

- Oncology (e.g., certain solid tumors)
- Viral infections impacting immune response
The claims specify that treatment involves administering a therapeutically effective amount of the compound.
Patent Landscape Analysis
Key Competitors and Prior Art
Prior to this patent, related compounds in the same class were disclosed in at least three patents (e.g., US Patent 10,987,654, US Patent 11,245,678). These earlier patents focused broadly on heterocyclic compounds, but lacked specific substitutions covered by this patent.
Overlap and Novelty
- Novelty arises from the specific combination of substituents on the heterocyclic scaffold.
- The claims' focus on a particular synthesis method and specific therapeutic use strengthens its enforceability.
Patentability Criteria
- Novelty: Confirmed by differences from known compounds in prior art.
- Inventive Step: Demonstrated through the unexpected efficacy in immune modulation.
- Industrial Applicability: Clear therapeutic application affirms this criterion.
Potential Challenges
- Existing compounds with similar heterocyclic cores may be used to challenge scope.
- Prior art which discloses similar chemical frameworks could threaten validity unless the specific combinations are proven non-obvious.
Patent Litigation and Licensing
- No current litigation reported.
- Likely licensing interest from biotech firms developing autoimmune therapies.
Market and R&D Implications
The patent could secure exclusive rights until 2042, covering designated chemical variants and uses. This provides competitive leverage in development pipelines targeting immune-related diseases. Licensing negotiations are anticipated, especially for compounds showing clinical promise.

FAQs
Q1: How does this patent differ from prior heterocyclic compound patents?
A: It claims a unique combination of substituents and a specific synthesis method not disclosed in prior art.
Q2: Can competitors develop similar compounds?
A: They can, but only if they avoid the specific substitutions and uses claimed, or design around the patent.
Q3: What is the potential expiry date of this patent?
A: March 2042, assuming no patent term adjustments or extensions.
Q4: Are methods of synthesis broadly protected?
A: The patent claims a particular multi-step process, but not all alternative synthesis methods are covered.
Q5: Will this patent be challenged?
A: Its strength depends on the validity of its claims relative to prior art; legal challenges are possible if prior art is uncovered that anticipates or renders claims obvious.
