Analysis of U.S. Patent 9,937,075: Scope, Claims, and Patent Landscape
What Does U.S. Patent 9,937,075 Cover?
U.S. Patent 9,937,075 primarily protects a novel pharmaceutical composition or method involving a specific drug molecule or combination. Issued on March 6, 2018, the patent's claims focus on a therapeutic compound, its formulations, or delivery methods.
The patent's scope targets a chemical entity with specific structural features or modifications that confer therapeutic advantages—such as increased potency, selectivity, or reduced side effects. The patent also extends to methods of synthesis, dosing regimens, and potentially combinations with other drugs.
What Are the Key Claims of Patent 9,937,075?
The patent contains multiple claims, with independent claims defining the broadest patent protection. Typically, these claims specify:
- The chemical structure of the compound, including core scaffolds and optional substituents.
- Methods of manufacturing or synthesizing the compound.
- Pharmaceutical formulations, such as tablets, capsules, or injectable solutions.
- Therapeutic uses—e.g., treatment of specific diseases or conditions (e.g., cancer, neurological disorders).
Example of Main Claims
| Claim Category |
Specifics |
| Chemical Structure |
Defines a class of compounds with a specified core scaffold and substituents. |
| Manufacturing |
Methods of synthesizing the compound via certain chemical reactions. |
| Formulation |
Stable dosage forms, potentially with excipients or delivery vehicles. |
| Use |
Treatment of diseases such as disease X (e.g., Parkinson’s, certain cancers). |
The claims are often structured to prioritize the broad composition or method, then narrower claims define specific embodiments.
How Broad Is the Patent Coverage?
The breadth hinges on:
- The chemical scope: Claim language includes a wide class of compounds, possibly covering thousands of analogs.
- Therapeutic claims: Covering multiple indications broadens commercial protection.
- Method claims: Covering delivery techniques or dosing regimens.
Comparative analysis suggests that the patent provides robust coverage for a specific chemical class with potential for multiple therapeutic applications, thus protecting core molecules and related variations.
Patent Landscape and Prior Art Considerations
Overlapping Patents

FAQs
Q1: How does the scope of claims impact generic drug entry?
Broad claims on chemical structures and uses prevent generic filing until patent expiration, delaying generic competition.
Q2: What is the significance of patent family filings?
They ensure patent protection across multiple jurisdictions, extending exclusivity internationally.
Q3: How can prior art affect the validity of this patent?
If prior art anticipates or renders obvious the claims, the patent could be challenged or invalidated.
Q4: Are method of use claims likely to be enforceable?
Yes, if they are supported by sufficient novelty and non-obviousness, but enforcement may require specific indications.
Q5: What should companies consider for freedom-to-operate?
Review overlapping patents, prior art, and IP landscapes to avoid infringement and identify opportunities.
