The LTE sequel begins in much the same way as UMTS did—with an announcement of an industry initiative on the matter of essential IPRs. In LTE this scene took place in April 2008 where a group of leading telecommunication companies committed themselves to a framework for “establishing predictable and more transparent maximum aggregate costs for licensing [patents] that relate to 3GPP Long Term Evolution and Service Architecture Evolution (LTE/SAE) standards.” In particular, these companies stated “support” for “a reasonable maximum aggregate royalty for LTE essential IPR in handsets is a single-digit percentage of the sales price.”
