Cisco filed 8 IPRs on above three patents. All six Cisco IPRs on patents 8,341,679 and 8,984,565 were not instituted for interparties review. One IPR on 7,941,822 (claims 13, 14) was also not instituted but another IPR (IPR2016-01744) on 7,941,822 (claims 1,2, 5, 6, 19, 20, 23 and 29) was instituted for interparties review on March 3rd 2017. The decision on IPR2016-01744 that came out on Feb 23, 2018 sided with Cisco and stated that "Petitioner has demonstrated by a preponderance of the evidence that claims 1, 2, 5, 6, 19, 20, 23, and 29 of the ’822 patent are unpatentable."
Folks, in my view, the original trial with cable companies is still moving forward based on patents 8,341,679 and 8,984,565 and two claims 13, 14 of patent 7,941,822 !!!
