The PTAB’s decision in Microsoft Corp. v. Proxyconn, Inc., IPR2013-00026, IPR2013-00109, Paper  73, (February 19, 2014) is notable because for the first time a challenged claim (claim 24) survived the IPR Process, although 8 of the 9 claims for which trial was instituted were found invalid.  This makes the “kill” rate for patent claims in the first eight decisions 110/111 or 99.1%.

The other final written decisions so far are: Garmin International, Inc. v. Cuozzo Speed Technologies LLC, IPR2012-00001, Paper 59 (November 13, 2013) all three of the claims for which trial was instituted were found invalid; Idle Free Systems, Inc. v. Bergstrom, Inc., IPR2012-00027, Paper 66 (January 7, 2014), all 23 of the claims were found invalid, 9 by concession by the patent owner, and 14 by decision of the Board; Intellectual Ventures Management, LLC v. XILINX, Inc., IPR2013-00023, Paper 35 (February 11, 2014), all 19 claims were found invalid; Intellectual Ventures Management, LLC v. XILINX, Inc., IPR2013-00020, Paper 34 (February 11, 2014), all 12 of the claims for which trial was instituted were found invalid. Nicia Corp. v. Emcore Corporation, IPR2012-00005, Paper 68, (February 11, 2014), all 17 claims were found invalid; Intellectual Ventures Management, LLC v. XILINX, Inc., IPR2013-00019, Paper 33 (February 10, 2014), all 15 of the claims were found invalid; Intellectual Ventures Management, LLC v.
