John O’Quinn, partner at Kirkland & Ellis and counsel representing Time Warner at the Federal Circuit, argued that the entire verdict should be vacated, not just the damages portion, because the court allowed the jury to use a 2007 verdict granted to Sprint against Vonage on the same asserted patents as evidence to determine the damages award. That verdict involved the use of a 25 percent rule of thumb for determining a royalty rate, a rule that the Federal Circuit has subsequently held to be inappropriate in a landmark ruling in 2011. 

In two final decisions and five decisions on IPR institution, the PTAB panel of administrative patent judges (APJs) found that petitioners Apple and AT&T did not meet the required burden of proof to invalidate two VoIP-Pal patents. In the final written decisions, Apple and AT&T failed to prove invalidity of the challenged claims by a preponderance of the evidence. Similarly, the PTAB found that neither party had shown a reasonable likelihood of invalidity at the institution stage in the other cases. Along with last November’s denial of an IPR petition filed by Unified Patents, the VoIP-Pal patents have been unscathed through a total of eight IPR petitions.
