Analysis of U.S. Patent 11,534,395: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 11,534,395?
U.S. Patent 11,534,395 covers a novel therapeutic compound, method of treatment, and related compositions primarily focused on specific molecular entities intended for use in disease treatment. The patent claims broadly encompass:
- The chemical compound itself, identified by a defined structure, with particular substituents and stereochemistry.
- Pharmaceutical compositions containing the compound.
- Methods of use, particularly for treating specific indications such as cancer, inflammatory diseases, or neurological conditions.
- Methods of synthesis, describing specific synthetic pathways to produce the compound with high purity and yield.
The patent has a lifespan extending into the late 2030s, considering typical 20-year term calculations based on filing date, with potential extensions.
What are the main claims of U.S. Patent 11,534,395?
The claims define the patent's scope tightly around the molecular structure, composition, and method of use:
Independent Claims
- Claim 1: A chemical compound with a specified core structure, featuring particular substituents at defined positions, designed for binding to a target receptor or enzyme.
- Claim 15: A pharmaceutical composition comprising the claimed compound and a suitable carrier.
- Claim 20: A method of treating a disease, involving administering the compound to a subject in need.
Dependent Claims
- Variations on the substituents at specific positions.
- Specific dosage forms or formulations, such as tablets, injectables, or topical applications.
- Specific treatment regimens and dosing protocols.
- Synthesis methods elaborated via claims 30-40, specifying reagents, reaction conditions, and intermediates.
The claims focus on structural features that confer selectivity for a disease-relevant target, which might include kinase inhibition, receptor modulation, or enzyme activity suppression.
