When does a withdrawal of a patent term extension application become effective?
A withdrawal of a patent term extension application becomes effective when it is acknowledged in writing by the USPTO. According to MPEP 2764:
“An express withdrawal pursuant to this section is effective when acknowledged in writing by the Office.”
This means that simply submitting a withdrawal request is not sufficient. The withdrawal only takes effect after the USPTO has reviewed your request and provided written confirmation of its acceptance.
