Why was inter partes reexamination discontinued?
The discontinuation of inter partes reexamination was part of the broader patent reform implemented by the America Invents Act (AIA). While MPEP 2629 doesn’t provide the specific reasons, the change was made to improve the efficiency and effectiveness of patent review processes. The new inter partes review procedure conducted by the PTAB was designed to be a faster and more streamlined process for challenging patent validity.
