In the past, moving to amend the challenged claims during IPR was largely futile. The PTAB denied nearly all motions to amend, and many patent owners that might have benefited from amendment chose not to pursue it. But the rules concerning amendment in IPR are changing, and the number and success rate of motions to amend are ticking up. Patent owners have new reasons to think that amendment might save their patents from IPR.
In September 2018, the Patent Office created the Precedential Opinion Panel (or “POP”) to increase transparency and predictability of proceedings before the PTAB by establishing precedent that would guide all PTAB judges. In March 2019, the POP released its first opinion, which held that the PTAB may, in limited circumstances, join both a petitioner to a proceeding in which it is already a party and join new issues to an existing proceeding.
