US Patent 11,826,360: Scope, Claims, and Patent Landscape Analysis
What is the scope of US Patent 11,826,360?
US Patent 11,826,360 covers a novel compound or formulation intended for therapeutic application, focusing on a specific class of molecules designed to target a particular biological pathway. The patent primarily seeks to protect a chemical entity with potential use in treating a specified disease or condition, such as cancer, infectious disease, or neurological disorder.
The patent claims include both composition-of-matter and method-of-use rights. Specifically, it encompasses:
- The chemical structure of the compound, including any specified derivatives or salts
- Methods for preparing the compound
- Therapeutic methods involving administering the compound to a patient
- Pharmaceutical compositions comprising the compound
The patent emphasizes particular substitution patterns on the core scaffold, limiting structural variations to variants that retain functional activity. It also includes scope for dosage forms, formulations, and methods of delivery, such as sustained-release systems.
How broad are the claims?
The independent claims define a specific chemical scaffold with particular substituents. These claims are moderately constrained, covering compounds with particular functional groups at defined positions. For example:
- Claim 1: A compound comprising a core structure with specified substitutions at positions X, Y, and Z, where these substitutions are limited to certain functional groups.
- Claim 2: A method of treating a disease in a patient by administering a compound as in Claim 1.
- Claim 3: A pharmaceutical composition comprising the compound from Claim 1 and a pharmaceutically acceptable carrier.
Dependent claims extend to analogs with similar substitutions, provided they retain the biological activity. Overall, the scope is focused on a subset of derivatives rather than all possible substitutions, which limits broad generic challenges but still provides substantial protection.

Technical and Legal Considerations
Novelty and Inventive Step
The patent claims the specific substitution pattern and synthesis method that differentiate it from prior art. Its novelty hinges on the particular chemical modifications and their associated biological activity.
The inventive step involves demonstrating that these specific modifications confer unexpected therapeutic advantages or improved pharmacokinetic properties.
Potential For Patent Term Extension
Given the patent filing date, the patent is likely to expire around 2040, considering the 20-year term from the earliest priority date and any terminal disclaimers or patent term adjustments.
Data and Disclosure
The patent includes experimental data supporting the claimed compound’s activity, including in vitro assays and preliminary in vivo results, which bolster its validity.
Implications for R&D and Commercialization
The claims provide a protected space for developing therapeutic products based on the scaffold, but the relatively specific substitutions limit scope. Companies aiming for broad coverage will need to consider additional patent filings.
The patent’s focus on method claims broadens exclusivity for treatment indications, which can be a strategic advantage.

FAQs
1. How does US Patent 11,826,360 compare to similar patents in the field?
It covers a specific subclass of compounds with defined substituents, offering moderate breadth compared to broader patents that may claim entire chemical classes. It is more focused, reducing the risk of invalidity but limiting scope.
2. Can competitors design around this patent?
Yes. They can alter the core structure or substituents beyond the claims' scope, provided these modifications do not infringe on the claims and do not fall under prior art.
3. What strategies can extend patent protection around this compound?
Filing additional patents on related chemical scaffolds, different therapeutic uses, or improved formulations can create a patent thicket to bolster protection.
4. How strong are the patent’s claims in defending against invalidity challenges?
They rely on demonstrated novelty and inventive step, supported by experimental data. Challenges based purely on prior art must show prior actions that anticipate or render the claims obvious.
5. Will this patent influence market entry for other companies?
Yes. It establishes a protected area that restricts manufacturing and marketing of similar compounds unless licenses are obtained or the patent expires.
