Scope and Claims of US Patent 9,180,096

US Patent 9,180,096 pertains to a novel pharmaceutical composition designed for the treatment of specific diseases, with an emphasis on targeted drug delivery systems. The patent claims focus on the composition's structure, formulation, and methods of manufacturing, with broad implications for pharmaceutical innovation.

Key Claims Overview

Independent Claims

• The primary independent claim (Claim 1) describes a pharmaceutical composition comprising a specific active ingredient and a carrier. The active ingredient is characterized by a particular chemical structure, involving a substituted pyrrolidine core. The composition is formulated for oral administration and includes a controlled-release mechanism.

Dependent Claims

• Claims 2 to 15 specify particular embodiments:
  • Variations in the chemical substituents on the core structure.
  • Types of carriers used in the formulation (e.g., polymers, lipids).
  • Specific release profiles (e.g., sustained-release over 24 hours).
  • Methods of manufacturing, including specific steps such as granulation and coating processes.
  • Formulation into dosage forms, such as tablets or capsules.

Scope of Protection

• The claims broadly cover both the chemical compounds with the described core and their formulations with various carriers.
• The patent explicitly claims methods of making the compositions, which could restrict generics from producing similar formulations without licensing.
• The claim language emphasizes "comprising" rather than "consisting of," opening the scope to include additional components not explicitly listed.

Limitations and Exclusions

• The claims exclude certain chemical modifications that significantly alter the structure.
• The patent does not claim specific therapeutic indications but focuses on composition and formulation aspects.
• The scope is limited geographically to the United States, with potential extensions via international filings.
