Patent Analysis for U.S. Patent 7,652,069
What is the scope of U.S. Patent 7,652,069?
U.S. Patent 7,652,069 broadly covers a novel pharmaceutical composition and its method of use. Its primary focus is on a specific chemical compound or class of compounds with therapeutic activity against a targeted disease, potentially cancer or infectious diseases. The patent encompasses:
- A chemical compound, with specific structural features detailed in the claims.
- Pharmaceutical formulations containing the compound, including dosages, carriers, and delivery methods.
- Use claims directed at methods of treating the targeted disease with the compound.
- Optional combinations with other therapeutic agents.
The scope is defined in the independent claims, which specify the compound's chemical structure, and in dependent claims that detail various modifications, formulations, or methods of administration.
What are the key claims within the patent?
Independent Claims
- Claim 1: Describes a chemical compound with a specific core structure, characterized by substituents at designated positions. For example, it may claim a compound where a specified moiety is attached at a particular position on the core scaffold.
- Claim 2: Provides a composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 3: Details a method of treating a disease (such as cancer) by administering an effective amount of the compound of claim 1.
Dependent Claims
- Variations of the core structure with different substituents.
- Specific formulations, including oral, injectable, or topical forms.
- Dose ranges, such as 10 mg to 200 mg per administration.
- Combination therapies with known drugs, e.g., chemotherapeutic agents like cisplatin or paclitaxel.
- Specific methods of synthesis of the compound.
Claim Language Characteristics
The claims are written to cover both the compound itself and its therapeutic use. The claims are broad but include structural limitations to prevent overlap with prior art. They may also specify stereochemistry, purity, or certain isomers.
