Final Patent Rejection Flip

My Canadian client faced a final office action rejecting their patent application.

The Canadian patent agent told us we had no options; they went through the motions.

With the client's approval I fired the patent firm, hired a new one, and they made an appointment for the inventor to meet the Examiner and a US patent attorney in Alexandria, VA. At this face-to-face meeting the inventor convinced the Examiner of the novelty of an invention enabling MC-1 chemotherapy drug conjugate to be magnetically targeted into tumors. The patent prosecution flipped from a final rejection to a Notice of Allowance in a 60-day period.
