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.
