Detailed Analysis of U.S. Patent 7,910,605: Scope, Claims, and Patent Landscape

What Is the Scope of U.S. Patent 7,910,605?

Patent 7,910,605, issued March 8, 2011, claims an inventive composition and methods related to a compound with specific therapeutic applications. It primarily covers substituted heterocyclic compounds with identity to a core structure described in the application, along with their pharmaceutical compositions and uses.

The patent’s core lies in its chemical composition, with broad claims covering derivatives that share the same core structure but differ by substitutions. The scope extends to methods of synthesis, formulations, and medical uses targeting specific diseases, notably cancer and inflammatory conditions.

Key Features

• Core chemical structure: The patent describes a heterocyclic compound with specific substituent variables.
• Substituent variations: Claims encompass derivatives where various chemical groups are attached at defined sites.
• Methods of synthesis: The patent includes claims on processes to produce the compounds.
• Therapeutic applications: The claims specify use in treating cancer, inflammation, or related diseases via the compounds.

What Are the Main Claims of U.S. Patent 7,910,605?

The patent comprises multiple claims, categorized as independent and dependent. The independent claims define the scope of the invention broadly:

Example of Independent Claims:

• Claim 1: A heterocyclic compound with a specific core structure, where the substituents at certain positions are defined within a range of options.
• Claim 11: A pharmaceutical composition comprising the compound claimed in claim 1, combined with a pharmaceutically acceptable carrier.
• Claim 17: A method of treating cancer or inflammation comprising administering an effective amount of the compound.

Dependent Claims:

• Variations on substituent groups.
• Specific embodiments targeting particular diseases.
• Synthesis methods with detailed steps.

Claim Scope Analysis

The claims are broad but specific enough to cover:

• Variants of the core heterocyclic structure with different substituents.
• Methods for preparation.
• Uses in treating specified diseases.

However, the scope is limited to compounds and methods explicitly described and claimed within the patent.
