On September 18, 1957, Blank, Grinich, Kleiner, Last, Moore, Noyce, Roberts, and Hoerni resigned from Shockley Labs.[28] They became known as the "traitorous eight", though it is not known who coined the term.[21][66] Shockley could never understand the reasons for this defection.[67] After that time, he never talked to Noyce again,[63] but continued to follow the work of "The Eight".[68] He also combed through all records left by The Eight, basing patents, held as Shockley Labs' intellectual property, on any important ideas.[68] (Technically, in accordance with U.S. law, those patents were issued to the respective inventing employees.)
