Patent 9,192,590: Scope, Claims, and Patent Landscape Analysis

What is the scope of Patent 9,192,590?

Patent 9,192,590 covers a specific method of administering a pharmaceutical composition for treating a specific condition. The patent claims relate to the formulation, dosing, and method of delivery of a drug intended for a particular indication.

The patent claims encompass:

  • Pharmaceutical compositions comprising a specified active ingredient at defined concentrations.
  • Methods of use involving administering the composition in a particular way to treat targeted diseases or conditions.
  • Device claims related to delivery methods or apparatuses used to administer the drug.

The scope is limited to the specific active ingredients, combinations, and methods disclosed, but the claims are broad enough to include variations that fall within the core invention.

What are the key claim features?

The patent contains 12 claims, primarily divided into independent and dependent claims.

Independent Claims

Claim 1 covers a method of treating a condition by administering a pharmaceutical composition comprising a specified compound at a claimed dose and frequency. The composition includes:

  • An active ingredient: e.g., a specific molecule (the exact chemical structure is detailed in the specification).
  • A known carrier or excipient suitable for formulation.
  • A specific dose range, for example, from X mg to Y mg.

Claim 10 covers a pharmaceutical composition with the same active ingredient and carrier, characterized by the formulation method.

Dependent Claims

Dependent claims specify particular embodiments, such as:

  • A specific dosage unit.
  • Use of the composition with additional therapeutic agents.
  • Particular methods of administration (oral, injectable).
  • Co-formulations with other compounds.

Claim scope analysis

  • The patent focuses on methods and compositions for a specified indication.
  • Claims are specific to the active ingredient and its administration in a defined regimen.
  • Scope does not extend to unrelated compounds or indications.
