This list represents a significant portion of the litigation initiated but may not be exhaustive. The high volume of cases filed in multiple jurisdictions, followed by termination, is characteristic of a widespread patent assertion campaign. It is also worth noting that related patents in this family were subject to reexamination requests filed by the Electronic Frontier Foundation (EFF), which argued that the claimed inventions were not novel.
