What Are the Scope and Key Claims of US Patent 8,106,183?
Scope of the Patent
US Patent 8,106,183 claims a novel formulation or method involved in drug delivery or composition, possibly within the fields of pharmaceuticals such as biologics, small molecules, or combination therapies. The patent emphasizes specific features that distinguish it from prior art, including chemical structures, dosage forms, or production processes.
Main Claims Breakdown:
- Claim 1: Usually the broadest, defining the core inventive concept—likely a pharmaceutical composition comprising specific active and excipient components arranged in a particular manner.
- Dependent Claims: Clarify details like concentrations, molecular structures, methods of synthesis, or specific therapeutic applications.
- Method Claims: Cover processes of making or using the formulation, potentially involving administration techniques or dosing regimens.
Representative Claim Elements (Hypothetical):
- Use of a unique excipient or carrier that enhances drug stability or bioavailability.
- Specific chemical modifications of an active compound to improve efficacy.
- A formulation that reduces side effects or increases patient compliance.
Claims Scope Limitations
- Patent scope remains limited to the described embodiments. Claims outside these definitions are not protected.
- Narrower dependent claims limit the scope relative to the broad independent claims but add defensibility.
