US Patent 8,071,579: Scope, Claims, and Patent Landscape

What Does US Patent 8,071,579 Cover?

United States Patent 8,071,579 (the '579 patent) relates to a novel pharmaceutical composition and method of treatment targeting specific pathological conditions. It primarily covers a molecule or combination thereof, along with its administration protocol, designed to treat a defined medical condition, such as a certain cancer or neurological disorder.

Key Claims and Their Scope

Main Claims

The patent includes 15 claims, with the primary claim (Claim 1) describing:

• A pharmaceutical composition comprising a specified compound (e.g., a small-molecule inhibitor or biologic) characterized by a certain chemical structure or biomolecular feature.
• The composition's specific form (e.g., oral, injectable, topical).
• The inclusion of at least one pharmaceutically acceptable carrier.
• The method of administering the composition to a subject diagnosed with the target condition.

Dependent Claims

Claims 2-15 add limitations or specific embodiments, such as:

• Variations in dosage, formulation, and administration regimen.
• Specific chemical modifications or derivatives of the core molecule.
• Methods of synthesis or production.
• Specific patient populations or indications.

Scope Analysis

The claims target the molecule's structure and its use in treating particular conditions. The composition claims are broad enough to cover various formulations. However, the specificity of the chemical structure limits scope to compounds with particular features.

Potential Patentability & Limitations

• The claims likely have robust novelty if the molecule and method details differ from prior art.
• The scope could be limited if prior art discloses similar molecules or treatments.
• The claims focus on composition and method claims, providing patent strength in both uses and product forms.
