It is time to recognize the elephant in the room. The Patent Trial and Appeal Board (PTAB) is broken. And, if we want to be perfectly fair and reasonable in our assessment of the reasons that the PTAB is failing, the blame must trace all the way back to Congress. The creation of three new ways to invalidate patent rights was at best ill-conceived. The manner in which it was done clearly put the finger of infringers on the scale of justice. The creation of an open-ended second window for patents to endlessly be challenged without title ever quieting and ownership ever settling is making a mockery of patentownership.
My thoughts will be appended later. Patent Attorney client work never ends!
