The Loongson family was developed at the Institute of Computing Technology in China. It's based on the MIPS design but the original processors were missing 4 instructions covered by MIPS Technologies patents. ICT now licence the MIPS architectures directly from MIPS Technologies, so there's nothing stolen about it.
