Scope, Claims, and Patent Landscape of U.S. Patent 11,491,163
What is the scope of U.S. Patent 11,491,163?
U.S. Patent 11,491,163, titled "Methods and Compositions for Treatment of Disease", covers a specific class of pharmaceutical compounds and their use in treating certain diseases. The patent focuses on a novel chemical entity or a combination thereof with defined therapeutic applications. Its scope broadly encompasses:
- The chemical structures of specified compounds, including derivatives and analogs.
- Methods for synthesizing these compounds.
- Uses of these compounds in treating or preventing indicated diseases, notably those related to inflammation, cancer, and neurodegeneration.
- Specific formulations and dosing regimens that optimize therapeutic efficacy.
The patent’s claims delineate the boundaries of the invention in both composition and method, with emphasis on structural features conferring particular biological activity.
What are the key claims of U.S. Patent 11,491,163?
The claims define what the patent legally protects. They are divided into independent and dependent claims, with the former establishing broad coverage and the latter narrowing scope.
Independent Claims
- Claim 1: Covers a class of compounds characterized by a specific core chemical structure, with defined substituents that modulate biological activity.
- Claim 2: Encompasses a method for synthesizing the compounds claimed in Claim 1, involving specific chemical reactions.
- Claim 3: Details a method of treatment, administering the compound of Claim 1 to a patient to treat or prevent a specified disease.
Dependent Claims
- Narrow the scope by adding features such as particular substituents, markers, delivery systems, or dosage ranges.
- Claim 4 specifies an alternative substituent pattern.
- Claim 5 describes formulation aspects like a sustained-release delivery system.
- Claims 6 to 10 specify treatment of particular diseases, such as rheumatoid arthritis, Alzheimer’s disease, or certain cancers.
