Can a patent application be rejected after it has been allowed?

Yes, a patent application can be rejected after it has been allowed. According to MPEP 706.05, rejection after allowance is possible. The section states:

“See MPEP § 1308.01 for a rejection based on a reference after allowance.”

This means that even after an application has been allowed, new information or references may come to light that could lead to a rejection. It’s important for applicants and patent attorneys to be aware that allowance doesn’t guarantee final approval.
