Advanced Audio’s petition for writ of certiorari notes, all five patents were filed with the U.S. Patent and Trademark Office prior to the enactment of the America Invents Act (AIA), which established the PTAB. Prior to Congressional passage of the AIA, Advanced Audioe didn’t need much litigation of its patent rights to license its patents and achieve most of its revenue. After the AIA passed, Advanced Audio began having to again file suits against those who were practicing its patented technology without a license. The patents invalidated by the PTAB were asserted by Advanced Audio in cases against Amazon, HTC and Pantech Wireless all filed in the Northern District of Illinois. Those cases are stayed in district court pending the resolution of this case, which has created significant costs through attorney fees and significant loss of royalty revenue.
