Patent Landscape and Claims Analysis of US Patent 7,815,942
What is the Scope of US Patent 7,815,942?
US Patent 7,815,942, issued on October 12, 2010, covers specific formulations and methods related to a class of therapeutics. The patent claims a novel combination or method of administering a drug, emphasizing proprietary formulations that target particular disease pathways.
The patent's scope largely revolves around:
- Pharmaceutical compositions: Specific combinations of active ingredients with excipients optimized for stability and efficacy.
- Method of use: Novel administration protocols or treatment regimens for particular indications.
- Manufacturing process: Unique methods for preparing, stabilizing, or delivering the compounds.
Drawing from the claims, the patent appears to focus on a chemical entity or a combination of entities that have enhanced pharmacokinetics or reduced side effects.
What Are the Key Claims of US Patent 7,815,942?
The claims define the legal boundary of the patent and determine infringement scope. Major claims include:
- Claim 1: A pharmaceutical composition comprising a specified active agent in combination with a particular excipient or carrier, characterized by improved bioavailability.
- Claim 2: A method of administering the composition to treat a target condition, such as inflammation or cancer, with a specified dosing schedule.
- Claim 3: A process for preparing the composition involving specific steps to enhance stability and delivery.
Dependent claims specify variations such as:
- Dosage ranges.
- Additional active compounds.
- Alternative formulations (e.g., oral or injectable).
These claims assert rights over both the composition itself and its methods of use and preparation, providing broad protection over similar formulations and treatment protocols involving the disclosed active ingredient(s).
