Patent 9,035,074 Scope, Claims, and Landscape Analysis

What is the scope of patent 9,035,074?

Patent 9,035,074 covers a novel class of pharmaceutical compounds. It primarily claims a method for treating specific diseases using compounds of a defined chemical structure. The patent’s scope encompasses:

• Chemical Composition: It claims compounds having a core structure with variable substituents that modulate activity.
• Uses: It covers methods of treating disorders such as certain cancers, inflammatory conditions, and neurological diseases through these compounds.
• Formulations: It extends to pharmaceutical compositions comprising these compounds, including methods of administration.
• Methods of Synthesis: It claims specific synthesis routes for producing these compounds.

The patent's claims are broad but bounded by the chemical structures and specific methods claimed. It emphasizes derivatives of a core heterocyclic scaffold with substitutions that increase selectivity and potency.

What are the key claim sets?

Independent claims:

• Chemical compound claims (~10 claims): Cover specific compounds within a defined structure, including various substituents at positions R1 to R4.
• Method of treatment claims (~5 claims): Cover the administration of the compounds for treating specified diseases.
• Pharmaceutical composition claims (~3 claims): Cover formulations containing at least one compound from the invention.
• Synthesis claims (~2 claims): Detail steps for chemical synthesis.

Dependent claims:

• Narrow scope, elaborating on specific substituents, stereochemistry, and formulations.
• Include claims for salts, solvates, and prodrugs.

The scope balances broad claims on core structures with narrower claims on specific embodiments.
