Overview of U.S. Patent 11,273,160
U.S. Patent 11,273,160 pertains to a pharmaceutical compound or formulation, issued on March 8, 2022. Its scope covers a specific chemical entity or class, along with methods of manufacture, use, and potential therapeutic applications.
Scope and Claims Analysis
Broadness of Claims
The patent primarily claims a compound described by a structural formula, with defineable substituents. The core claim likely covers:
- The chemical structure, with specific substituents.
- Variations of the structure, including isomers, salts, and stereoisomers.
- Methods of synthesis to produce the claimed compound.
- Therapeutic methods involving the compound, such as treating specific diseases or conditions.
The claims' broadest scope hinges on the structural formula, which often encapsulates a family of related compounds. Substituent variations and isomer claims extend coverage further.
Key Claim Elements
Structural Formula
The patent's main claim likely centers on a novel chemical structure, with permissible variations restricted by the definitions of R groups (e.g., R1-R4). These define the scope of protected compounds.
Method Claims
Claims may cover:
- Synthesis processes for the compound.
- Methods of administering the compound for therapeutic purposes.
- Methods of manufacturing composition.
Use Claims
Use claims specify methods for treating particular conditions, possibly including specific indications like cancer, neurological disorders, or infectious diseases.
Novelty and Inventive Step
The patent claims a novel compound or class not previously disclosed in prior art. Patentability hinges on:
- Unique structural features distinguished from prior art molecules.
- Unexpected biological activity or efficacy.
- Stable synthesis pathways.
The patent examiner likely cited prior art references, but the application distinguished itself based on specific structural differences or surprising functional data.
