Patent family and priority data
- Filing date: December 20, 2017
- Publication date: July 1, 2020
- Priority applications: Filed internationally in multiple jurisdictions, including the US and PCT routes.
Patent classification
- International Patent Classification (IPC): A61K 31/00 (medicinal preparations containing organic compounds), A61K 35/76 (antineoplastic or immunomodulating agents), C07D 471/14 (heterocyclic compounds).
Main subject matter
The patent claims focus on:
- A specific chemical compound or class.
- Pharmaceutical compositions containing the compound.
- Methods of treating certain conditions (e.g., cancer, autoimmune diseases) using the compound.
The claims afford protection primarily to the compound's structure and its use in the specified indications. The claims exclude known prior art compounds and specify purity, formulation, or administration mode.
How broad are the claims?
