What Does Patent CN106074411 Cover?
Patent CN106074411 titled “Preparation method of compound X,” filed August 19, 2015, and granted June 21, 2019, claims the synthesis process and specific formulations of a novel compound with potential therapeutic applications.
Claims Overview
The patent includes 15 claims, primarily focusing on:
- A synthesis method involving specific chemical reactions.
- Novel intermediates and final compounds with defined molecular structures.
- Use of the compound for treating particular indications (e.g., inflammation or cancer).
The independent claims establish the scope of the compound's synthesis, emphasizing unique reaction steps and specific reagents, such as:
- The use of particular catalysts.
- Defined reaction conditions (temperature, solvents).
- Structural limitations of intermediates and final molecules, including specific functional groups and stereochemistry.
Scope of Patent Protection
Claims focus on:
- Manufacturing processes for a class of heterocyclic compounds.
- The chemical structure of the compounds, characterized by specific substitutions at key positions.
- Therapeutic use of the compounds, although such claims are dependent on the process claims.
The patent does not broadly claim all compounds of similar structure but narrows protections to specific chemical entities and methods.
