Patent Analysis for US Patent 9,345,771

What is the scope of US Patent 9,345,771?

US Patent 9,345,771 covers a specific chemical composition and method related to a novel pharmaceutical compound. It is primarily focused on a class of molecules with defined chemical structures designed for therapeutic use. The patent claims the compound itself, its pharmaceutical compositions, and methods of treating specific conditions using these compounds.

Key Components of the Patent

  • Chemical Structure: Claims include a class of heterocyclic compounds with certain substituents, characterized by their core chemical scaffold.
  • Method of Use: Claims specify methods of administering the compound to treat diseases such as cancer and inflammatory disorders.
  • Pharmaceutical Composition: Details formulations including dosage forms, carriers, and delivery mechanisms.

Scope Limitations

  • The claims are confined to compounds with specific substituents and stereochemistry.
  • Therapeutic methods are limited to certain diseases explicitly mentioned.
  • The patent does not extend to compounds outside the defined chemical structure or use cases.

What are the claims made within US Patent 9,345,771?

The patent contains 16 claims, with the following key claims:

  • Claim 1: A compound with a chemical structure defined as a heterocyclic core with specific substituents (most comprehensive claim).
  • Claim 2-10: Variations of the chemical structure, specifying different substituents or stereoisomers.
  • Claim 11: A pharmaceutical composition comprising at least one compound as claimed in Claim 1 or 2-10.
  • Claim 12-15: Methods of treating cancer or inflammatory diseases by administering the compound.
  • Claim 16: A process for preparing the compound.

Claim Scope Analysis

Claim 1 is broad and defines the core chemical structure extensively, providing protection for similar compounds within the same chemical class. The subsequent claims narrow the scope to specific variants and uses. Claims 12-15 specify therapeutic methods, offering patent protection for treatment applications.
