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 identified prior-filed pending applications and issued a descriptiveness refusal. These are serious issues that may not be fixable, and you should contact us to discuss this before hiring us.
