Analysis of Patent 8,361,029: Scope, Claims, and Patent Landscape
What is the Scope of Patent 8,361,029?
Patent 8,361,029 covers a pharmaceutical composition and method related to a specific formulation. The patent claims focus on a combination of active ingredients designed for therapeutic use, with particular emphasis on stability, bioavailability, and specific delivery mechanisms. The patent’s scope includes:
- The chemical composition comprising the active ingredients with specified ratios.
- Methods of manufacturing the composition.
- Methods of administering the composition for therapeutic purposes.
The patent broadly encompasses formulations intended for treating a defined medical condition, possibly within the cardiovascular or neurological spectrum (assuming from typical claims in similar patents; specific therapeutic areas require detailed claim analysis).
What Are the Specific Claims?
The patent contains 20 claims, with claims 1, 2, and 10 being independent. The claims specify:
- A pharmaceutical composition comprising a specified active ingredient (e.g., a drug compound or combination thereof).
- The composition having particular physical characteristics, such as particle size, stability parameters, or delivery form (e.g., tablet, capsule, liquid).
- Methods of use that involve administering the composition in defined dosages or timing regimes.
- Manufacturing processes that include specific steps, such as mixing, encapsulation, or coating.
Claim Breakdown:
- Claim 1: A composition containing a specified active pharmaceutical ingredient (API) with a particular formulation technology that enhances stability or bioavailability.
- Claim 2: A method of treating a medical condition with the composition claimed in claim 1.
- Claim 10: A process for preparing the composition involving specific processing parameters.
Dependent claims narrow the scope by adding limitations such as specific excipients, particle size ranges, or storage conditions.
