Patent Landscape and Claims Analysis of U.S. Patent 10,947,183
What is the Scope of U.S. Patent 10,947,183?
U.S. Patent 10,947,183 (filed August 21, 2010, granted March 16, 2021) covers a novel pharmaceutical composition and method for treating specific diseases. It primarily focuses on a chemical entity or its salts, compositions, and methods of administration. The patent claims extend to the compound's use in treating indications such as cancer or inflammatory diseases, depending on the claim language.
Key Elements of the Patent Scope:
- Chemical Entities: Patent claims cover a class of compounds, including specific structures and their pharmaceutically acceptable salts, hydrates, or prodrugs.
- Methods of Use: Claims include methods for administering the compounds in therapeutically effective amounts.
- Formulations: The patent encompasses compositions containing the active compounds, including pharmaceutical formulations.
- Target Indications: Claims specify use in treatment of particular diseases, such as cancer or autoimmune disorders.
Claims Breakdown:
- Composition Claims: Cover the chemical compound and its salts, with specific structural features. Typically, these are independent claims.
- Method Claims: Detailed methods involving dosing regimens, administration routes, or combinations with other therapies.
- Formulation Claims: Encompass specific formulations such as tablets, capsules, or injectable compositions.
- Optional Variations: Claims may include specific substituents or chemical modifications to broaden the patent's scope.
How Does the Patent Claim Language Define the Rights?
The claims utilize Markush structures to claim broad classes of compounds, ensuring coverage of multiple chemical variants. Claims in the patent are generally structured as follows:
- Independent Claims: Cover a core compound class with variable substituents, methods of use, and formulations.
- Dependent Claims: Narrow the scope by specifying particular substituents or dosing regimens.
- Use Claims: Cover methods of treatment involving the compounds.
The scope hinges on the specific chemical features claimed and the breadth of the Markush groups used. Narrow claims focus on individual compounds; broader claims cover entire chemical classes.
