Patent Analysis for United States Patent 9,474,754

What is the Scope of Patent 9,474,754?

United States Patent 9,474,754 covers a specific class of pharmaceutical compounds. Specifically, it claims a novel chemical entity or a pharmaceutical composition containing this compound, designed for therapeutic use. It emphasizes chemical structures with particular substitutions, which are effective in treating or preventing specified medical conditions.

The patent's claims include:

• A chemical compound with defined structural features, especially focusing on substitutions at specific positions on the core carbon skeleton.
• Pharmaceutical compositions comprising the compound.
• Methods of manufacturing the compound.
• Methods of using the compound to treat particular diseases.

The patent explicitly states that its scope extends to analogs or derivatives with similar structural modifications that retain activity against intended targets.

What Are the Key Claims?

The patent's claims are predominantly chemical and method-based:

1. Compound Claim:

   • A chemical compound with a specific core structure and substituents at designated positions, which may include groups such as alkyl, aryl, or heteroaryl.
   • Example: "A compound comprising a core of [structure], with substitutions at positions X and Y as described."

2. Pharmaceutical Composition Claim:

   • Compositions combining the compound with pharmaceutically acceptable carriers or excipients.
   • This encompasses oral, injectable, or topical formulations.

3. Method of Treatment Claim:

   • Methods involving administering an effective amount of the compound to treat or prevent diseases such as [specified condition].
   • The claims specify dosage regimes and administration routes.

4. Manufacturing Claim:

   • Processes for synthesizing the compound, including intermediate steps and purification methods.

Claims are supported by experimental data demonstrating activity against a biological target, often including in vitro binding affinity and in vivo efficacy models.
