The America Invents Act (AIA) created new US post-grant patent challenge proceedings—including inter partes review (IPR). Conducted in the United States Patent and Trademark Office (USPTO), post-grant challenges are adjudicated by administrative patent judges (APJs) of the Patent Trial and Appeal Board (PTAB). Post-grant challenges have proved popular with patent challengers because: they are faster and cheaper than traditional district court litigation;1 the standard to invalidate a patent is lower than that employed by district courts;2 claim interpretation is broader—potentially opening up claims to a wider prior art pool;3 the ability to amend claims is practically nonexistent;4 and APJs are perceived as being more technologically savvy than judges and juries sitting in federal district courts.5
