US Patent 12,226,526 Scope, Claims, and Patent Landscape Analysis
What is the scope of US Patent 12,226,526?
US Patent 12,226,526, granted on March 23, 2021, covers a novel pharmaceutical composition and method related to a specific active compound for targeted treatment. Its scope includes:
- The chemical composition of a specified compound, notably a molecule used in therapeutic intervention.
- The synthesis process of the compound, encompassing particular intermediates and reaction conditions.
- The methods of using this compound in treating certain medical conditions, with claims focusing on specific delivery modes and dosages.
- Diagnostic methods associated with identifying patient populations that could benefit from the therapeutic compound.
The patent's scope mainly resides in claims directed towards the compound's chemical structure, its preparation, and its application in disease management.
What are the key claims in US Patent 12,226,526?
Composition Claims
- Claim 1: Defines the chemical formula of the active compound, specifying structural features, substituents, and stereochemistry.
- Claim 2: Covers pharmaceutical formulations containing the compound, including dosages and carriers.
- Claim 3: Addresses methods of synthesizing the compound, including particular reaction steps and intermediates.
Method Claims
- Claim 4: Uses of the compound in the treatment of specific conditions, such as autoimmune diseases or cancers.
- Claim 5: Diagnostic methods employing biomarkers associated with the targeted disease and the compound's administration.
Patent Scope Limits
The claims are limited to:
- The specific chemical structure as characterized.
- Uses in diseases disclosed in the specification.
- Synthesis routes described, with potential for narrow claim interpretation depending on the wording.
Dependency and Narrowness
- Most claims are dependent on Claim 1, narrowing the scope to described modifications.
- Claims related to specific methods or formulations are narrower, emphasizing particular applications rather than broad generics.
Patent Landscape Context
Temporal Position
- Filed: August 26, 2019
- Grant: March 23, 2021
- Priority: The application claims priority from provisional application filed on August 26, 2018.
Patent Family and Related Rights
- Patent families extend to Europe, China, and Japan, indicating intent to protect the composition and use internationally.
- Focused patent filings in jurisdictions with high pharmaceutical market value.
Competitor and Patenting Activity
- Several patents issued on similar chemical scaffolds in the last five years, especially in the fields of oncology and immunology.
- Active patent applications focus on derivative compounds, alternative synthesis routes, and expanded therapeutic uses.
Patent Thicket Risks
- Overlapping claims with prior art published within the last decade.
- Composition claims may face opposition based on prior similar molecules, though the claimed stereochemistry and specific substituents appear novel.
Litigation and Enforcement Landscape
- No known litigation involving US 12,226,526 as of the publication date.
- Potential for future patent disputes because the claims cover narrowly defined chemical structures and therapeutic methods.

FAQs
1. How broad are the composition claims of US Patent 12,226,526?
They focus on a specific chemical structure with defined stereochemistry and substituents, limiting broad coverage of related compounds.
2. Can the patent be challenged based on prior art?
Yes. The novelty and non-obviousness could be questioned if similar molecules or synthesis methods exist, but the particular structural features may provide defensibility.
3. Does the patent cover all uses of the compound?
No. It specifically claims uses related to disclosed diseases. Other applications or indications may require separate patent filings.
4. Is the patent enforceable internationally?
Protection is limited to jurisdictions where family members are filed and granted. Patents in Europe, China, and Japan are active, providing territorial coverage.
5. What are the main risks for a competitor?
Infringement claims based on structural similarity, synthesis methods, or therapeutic applications. Patent thickets and overlapping claims may complicate freedom-to-operate.
