Most of those 62 lawsuits were thrown out on procedural grounds, such as lack of standing (which I think was a bad reason: if the losing candidate doesn't have standing to challenge an allegedly fraudulent voting system, then who does?). But that means they never reached the fact-finding stage, so citing those cases as meaning "there was no fraud" is not supported by the evidence. The cases thrown out on procedural grounds only mean "no conclusion was reached on whether the facts alleged in the complaint were true".
