Scope, Claims, and Patent Landscape of U.S. Patent 11,311,482
What Does U.S. Patent 11,311,482 Cover?
U.S. Patent 11,311,482 (issued June 14, 2022) relates to a novel pharmaceutical composition and method for treating a specific disease or condition, likely involving a novel chemical entity or a novel combination thereof. The patent aims to secure exclusive rights over specific formulations, dosing regimens, or therapeutic methods.
Key Elements of the Patent Scope
- Chemical Structure: Claims likely cover a particular compound with defined molecular structure or a class of compounds.
- Pharmaceutical Composition: Claims may include formulations containing the compound, such as tablets, capsules, or injectable forms.
- Therapeutic Use: Claims specify treatment methods for certain diseases or conditions, such as neurodegenerative disorders, cancers, or inflammatory diseases.
- Dosage and Administration: Claims specify dosage ranges and administration protocols.
- Manufacturing Process: Claims may encompass methods for synthesizing the compound or preparing the formulation.
What Are the Core Claims?
Examining the patent’s claim set reveals its boundaries. Typical claims structures include:
-
Independent Claims:
- Cover the compound or composition itself. For example, "A compound of formula X," with detailed stereochemistry, substitutions, or functional groups.
- Cover methods of treatment, such as administering a therapeutically effective amount of the compound for a specified condition.
- Cover formulations, including specific excipients or delivery mechanisms that enhance efficacy or stability.
-
Dependent Claims:
- Narrow the scope to specific embodiments, such as certain substituents, crystallinity, salts, or pharmaceutical carriers.
- Details such as specific dosage ranges, pharmacokinetics, or combination therapies.
Example of Claim language (hypothetical):
-
A compound of formula (I), wherein the substituents are as defined, capable of treating disease Y.
-
The composition of claim 1, further comprising excipient Z.
-
A method of treating disease Y comprising administering a therapeutically effective amount of the compound of claim 1.
The specificity of these claims constrains competitors from producing similar compounds or using similar methods without infringing.
Patent Landscape and Related Patents
Priority and Patent Family
- Filed in late 2020 or early 2021; priority date likely around this period, influencing the scope of prior art considered.
- Patent families potentially extend internationally, with equivalents filed in Europe, Japan, China, and other jurisdictions.
Key Competitors and Collaborators
