ITC judge says 3 companies didn’t violate Rambus’ patents

The ITC’s final decision, however, isn’t expected until July

Things aren’t looking good for Rambus Inc. at the moment. The technology licensing giant looks to be losing the early rounds of its patent infringement litigation against a litany of companies.

International Trade Commission (ITC) Judge Theodore Essex said Friday that chipmakers LSI Corp. and MediaTek Inc., and chip design company STMicroelectronics NV, did not violate Rambus’ chip technology patents. Rambus is accusing a number of companies of infringing six of its patents for memory controllers and high-speed, chip-to-chip communications, among other things.
