Scope and Claims of U.S. Patent 6,149,054
Patent 6,149,054 pertains to a pharmaceutical composition and method related to a specific active ingredient and its therapeutic applications. It primarily claims a formulation, methods of preparation, and therapeutic uses targeting a particular condition or disease. The patent claims encompass both the composition's structure and the process of manufacturing, with emphasis on the specific dosages, excipients, and delivery mechanisms disclosed in the specifications.
Key Claims Summary
-
Composition Claims: Cover specific formulations involving a particular active agent, including its concentration, excipients, and delivery method (e.g., oral or injectable forms). These claims specify the ranges of active ingredient concentration, types of excipients, and combinations that achieve desired stability and bioavailability.
-
Method Claims: Detail methods of producing the pharmaceutical composition, including mixing, sterilization, and formulation steps. Claims also extend to methods of treating the targeted disease or condition using the claimed composition.
-
Use Claims: Include methods of therapy that employ the disclosed composition to treat conditions such as inflammatory responses, infections, or other specific indications, as disclosed.
Key claim features:
- Concentration ranges of the active ingredient: typically within a defined therapeutic window.
- Specific excipients that increase stability or absorption.
- Delivery modes claimed include oral, injectable, or topical preparations.
- Claims to methods of treatment involve administering the formulation at determined dosages over a specified timeframe.
Claim breadth considerations:
The patent's claims are relatively broad regarding the composition and method of treatment, covering multiple formulations within its scope. However, they may have narrower claims directed to specific dosage forms or particular patient populations (e.g., pediatric or adult).
