The patent in question, US11097007B2, pertains to an injectable preparation comprising a composition that includes a poorly soluble drug, a dispersion medium, and specific additives to enhance the formulation's stability and efficacy[4].
Scope of the Patent
Definition of Scope
The scope of a patent is defined by its claims, which outline the boundaries of what is protected by the patent. The scope is a critical aspect in determining the patent's validity, enforceability, and potential for litigation[3].
Key Components of the Patent Scope
- Poorly Soluble Drug: The patent focuses on formulations that incorporate drugs with poor solubility, which is a common challenge in pharmaceutical development.
- Dispersion Medium: The use of a specific dispersion medium is essential to ensure the drug's stability and bioavailability.
- Additives: The patent specifies certain additives that are crucial for maintaining the formulation's viscosity, particle diameter, and concentration, all of which are vital for the injectable preparation's effectiveness[4].
Claims Analysis
Independent and Dependent Claims
The patent includes both independent and dependent claims. Independent claims stand alone and define the invention, while dependent claims build upon the independent claims and provide additional details or limitations.
- Independent Claims: These claims define the core invention, such as the composition of the injectable preparation and its key components.
- Dependent Claims: These claims specify additional features or limitations, such as the concentration of the drug, the type of dispersion medium, and the properties of the additives[4].
Claim Language and Scope
