Android devices running Java applications do not infringe on patents belonging to SIM card maker Gemalto, the U.S. Court of Appeals for the Federal Circuit ruled. Gemalto sued Google, Motorola, HTC and Samsung Electronics in 2010 in the U.S. District Court for the Eastern District of Texas, alleging that the companies infringed on three of its patents when running Java applications on their Android phones. Before Gemalto’s invention, personal computers with microprocessors could run Java applications, but these computers required a substantial amount of memory which was located on chips separate from the processor chip, called off-chip memory. Gemalto’s technology enabled devices with less memory to run applications written in high level programming languages such as Java.
