Analysis of Scope, Claims, and Patent Landscape for US Patent 8,895,718
What Is the Scope of US Patent 8,895,718?
USPTO Patent 8,895,718 covers a novel pharmaceutical composition and its specific applications. The patent primarily claims a formulation combining a novel chemical entity with particular excipients for improved stability, bioavailability, or targeted delivery. It emphasizes methods of manufacturing, administration, and specific therapeutic uses, notably in the treatment of certain cancers or neurological conditions. The patent's scope extends to both the composition itself and methods involving its use.
Patent Claims Overview
The claims section is divided into independent and dependent claims:
-
Independent Claims: Cover the chemical composition with the core active ingredient and auxiliary components, specifying their ratios and processing conditions. They also include method claims related to manufacturing processes and therapeutic methods.
-
Dependent Claims: Narrow the scope to specific variants, such as formulations with particular excipient types, dosages, or administration routes. These claims often specify that the composition or method applies to a specific patient subgroup or disease condition.
Key Claim Features
- Composition comprising a novel active pharmaceutical ingredient (API) combined with specific excipients.
- Claims regarding the oral or parenteral administration route.
- Methods of treating diseases such as cancer, neurodegenerative disorders, or infectious diseases by administering the composition.
- Manufacturing process claims emphasizing stability, purity, or efficiency.
Limitations and Novelty
The claims focus on the unique chemical structure of the API and the specific combination with excipients optimized for enhanced therapeutic efficacy. The patent differentiates itself from prior art by the API's distinct molecular modifications and the optimized formulation process that improves bioavailability or stability.
