The Itagaki opinion has sparked criticism.  Perhaps the most extreme is penned by the author of America’s most popular patent law blog, Eugene Quinn:

“[T]he Administrative Patent Judges that participated in [Itagaki] *** should be suspended or removed from the PTAB altogether, and if that isn’t possible *** they should simply be sidelined indefinitely. At least that way they cannot do any more damage.” [FN*]
