What information about the nonsigning inventor must be included in the patent application?
When filing a patent application with an unavailable joint inventor, you must include the last known address of the nonsigning inventor. As stated in MPEP 409.03(a):
“The last known address of the nonsigning joint inventor must be stated.”
For more details on providing this information, refer to MPEP 409.03(e). This requirement helps the USPTO in potential future communications and establishes that efforts were made to locate the inventor.
