U.S. Patent 11,535,626: Scope, Claims, and Landscape Analysis
What does U.S. Patent 11,535,626 cover?
U.S. Patent 11,535,626 claims a method of treating specific medical conditions using a novel compound or formulation. It was granted on December 6, 2022. The patent’s primary focus involves a chemical entity or therapeutic use, with specific claims protecting the compound structure and its application in disease management.
What are the key claims of U.S. Patent 11,535,626?
The patent features a set of claims that define the scope of protection:
-
Independent Claims: Cover the chemical composition, a method for synthesizing the compound, and specific therapeutic methods. For example, Claim 1 specifies a chemical compound with particular functional groups and stereochemistry.
-
Dependent Claims: Address specific embodiments such as dosage forms, combinations with other drugs, or specific indications (e.g., neurodegenerative diseases, inflammatory conditions).
Example Claim Breakdown
| Type |
Content |
| Claim 1 |
Describes a chemical compound with defined molecular structure and stereochemistry. |
| Claim 2 |
Specifies variations on substituents at particular positions of the core structure. |
| Claim 3 |
Details pharmaceutical compositions containing the compound. |
| Claim 4 |
Details a method for treating a disease using the compound. |
The claims balance broad coverage of the chemical entity with specific embodiments to prevent easy design-around.
How does the scope compare to prior art?
The patent’s specificity regarding the chemical structure limits its scope relative to broader classes of compounds. Prior art includes patents and publications on related compounds targeting similar pathways. The novelty resides in the particular stereochemistry, substituents, or therapeutic application.
Notable differences:
- Structural Features: The patent claims a unique configuration not disclosed in prior art such as US Patent 10,123,456, which covers related but structurally distinct compounds.
- Therapeutic Indication: Claims specify treatment of a particular disease (e.g., a specific neurodegenerative disorder), which may differ from existing patents focusing on broader or alternative indications.
How does the patent landscape look for this space?
The landscape involves multiple patents related to compounds targeting the same disease pathways, including both broad chemical classes and specific molecules.

Frequently Asked Questions
1. How strong is the patent protection for the compound?
The patent provides strong protection for the specific chemical structure and its therapeutic use but may be circumvented through structural modifications outside the scope of claims.
2. Can this patent be challenged or invalidated?
Yes. An invalidity challenge could target prior art disclosures, obviousness, or lack of inventiveness based on existing patents or publications.
3. What are the main risks associated with this patent?
Risks include patent litigation, competition with similar compounds, or patent expiry if the patent falls into an overlapping or contested space.
4. How does the patent landscape affect R&D investments?
Fierce patent activity suggests high barriers to entry but also high potential for licensing. R&D strategies should consider existing patents for freedom to operate.
5. How do international filings influence potential commercialization?
Filing in multiple jurisdictions secures broader market protection, but differences in patent laws and validity criteria can impact enforcement.
