The two companies informed a federal appeals court in Washington that their respective patent infringement cases against each other should be dismissed. The most high-profile case between Apple and Motorola began in 2010. Motorola accused Apple of infringing several patents, including one essential to how cell phones operate on a 3G network, while Apple said Motorola violated its patents to certain smartphone features. The cases were consolidated in a Chicago federal court. However, Judge Richard Posner dismissed it in 2012 shortly before trial, saying neither company had sufficient evidence to prove its case.
