What is an Office Action?
A USPTO Office Action is a formal letter from the examining attorney identifying issues in a pending application.
Some issues are procedural and can be corrected. Others are substantive refusals that require legal argument and evidence.
Receiving an Office Action does not automatically mean rejection. It means your application needs a response tailored to the specific refusal or requirement.
Procedural vs substantive issues
Procedural issues
These often involve wording, specimen formatting, or identification cleanup. They still require precision but may be more straightforward.
Substantive issues
These include legal refusals such as likelihood of confusion and descriptiveness, and typically require structured legal argument.
