Status 641 means the USPTO mailed a non-final Office Action identifying issues with your application. You typically have three months to respond with arguments, amendments, or evidence. Missing the deadline can abandon the application.

The USPTO examiner found no conflicting marks, but raised refusals under the Controlled Substances Act and Food, Drug, and Cosmetic Act, alongside requirements for information, identification amendments, class clarifications, and a substitute specimen.
