This patent is part of a larger family that has been subject to numerous post-grant proceedings before the Patent Trial and Appeal Board (PTAB), including Covered Business Method (CBM) reviews and Inter Partes Reviews (IPRs) on related patents. This history of administrative challenges suggests that the validity and scope of the patent claims have been scrutinized previously, which may be a factor in the ongoing district court cases. The litigation campaign by Authentixx LLC appears to be ongoing, with new cases filed as recently as April 2026.
