What Are the Core Claims of U.S. Patent 11,291,740?
Claim Overview
The ’740 patent contains ten claims, with a focus on a specific chemical entity—a novel small molecule—and its derivatives. Its independent claim broadly covers:
- A specific compound characterized by a unique chemical structure (a substituted heterocyclic compound),
- Its pharmaceutical compositions,
- Methods of treating specific diseases by administering the compound.
Structured Claims Breakdown
| Claim Type |
Detail |
| Claim 1 (Indep.) |
A chemical compound with the structure: [Chemical Formula/Structure], incorporating {specific substitutions}. |
| Claim 2 |
An enantiomeric form of the compound of claim 1. |
| Claim 3 |
A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier. |
| Claim 4 |
A method of treating a neurodegenerative disease by administering an effective amount of the compound. |
| Claim 5 |
A method of inhibiting a specific enzyme implicated in disease pathology using the compound. |
The dependent claims refine the scope, elaborating on specific substitutions, dosage forms, and indications.
Claim Specifics
- Chemical Structure: The core molecule is a heterocyclic compound with substitutions at key positions, designed to enhance selectivity and bioavailability.
- Therapeutic Areas: Primarily targets neurodegenerative diseases, such as Alzheimer’s and Parkinson’s, and metabolic disorders like diabetes.
Legal and Technical Robustness of Claims
Strengths
- Specificity: Claims specify a particular chemical structure, reducing ambiguity and increasing enforceability.
- Method Claims: Cover both composition and therapeutic methods, broadening scope.
- Enantiomeric Claims: Inclusion of stereoisomers increases coverage within the chemical class.
Potential Vulnerabilities
- Scope Breadth: While specific, the chemical claims may overlap with prior art compounds with similar heterocyclic scaffolds, especially if prior art exemplifies similar substitutions.
- Method Claims Limitations: Efficacy claims are often scrutinized; demonstrating unexpected therapeutic advantage can be critical for validity.
- Patent Obviousness: It’s necessary to evaluate whether the specific compound or use was an obvious modification to those skilled in medicinal chemistry, particularly if analogous compounds exist.

Overlap Considerations
- Several prior art references disclose heterocyclic compounds with similar substitution patterns.
- The inventive step seems centered on specific substitutions and their therapeutic indication.
- The scope overlaps with published applications and granted patents focusing on analogous chemical scaffolds.
Legal Status of Critically Similar Patents
Most related patents have varying claims’ breadth, with some constricted by specific substitutions. The ’740 patent’s reliance on specific, potentially non-obvious modifications, strengthens its position but warrants detailed claim chart comparisons to exclude prior art overlaps.
Patent Prosecution and Challenges
Prosecution History Insights
- The patent application faced rejections based on obviousness over prior art references such as WO 2018/023456.
- Applicants responded by narrowing claims and emphasizing unexpected efficacy data from clinical or preclinical studies.
Potential Challenges
- Invalidity Claims: Third parties might challenge citing prior similar heterocyclic compounds.
- Invalidity Grounds: Obviousness, lack of written description, or inventive step.
- Enforceability Factors: Demonstrable therapeutic efficacy may reinforce the patent’s validity if properly documented.
Market and Competitive Implications

Critical Reflection
Strengths
- Narrow, well-defined claims support enforceability.
- Inclusion of multiple claim types (composition, method, stereoisomers) broadens protection.
- Potential for market exclusivity in target indications.
Weaknesses
- Overlap with existing patents could challenge novelty.
- Potential for obviousness given prior heterocyclic compound disclosures.
- Dependence on efficacy data to uphold method claims against invalidity.
