HP is selling WebOS, acquired in 2011 when it bought Palm for $1.2 billion, to the Koreans.
The WebOS staff, associated web-sites, code and documentation will be transferred to LG but the basic patents remain with HP.
WebOS was designed for mobile devices and HP did launch TouchPad based on the OS but quickly withdrew it.
LG says it will use the OS for TVs.
Yesterday, at MWC, HP announced an Android-based tablet called Slate7.
