Lex Machina initially began in 2006 as a public interest project at Stanford University by Professor Mark Lemley and co-founders George Gregory and Joshua Walker.[5] The project was developed within the university's law school and computer science department under the IP Litigation Clearinghouse (IPLC) project.[4] Lex Machina was incorporated in 2008 and launched the following year.[6][7] The name "Lex Machina" is a Latin phrase meaning "law machine" that Walker had used in a research paper he wrote in 2004. Walker was named the CEO of the company until venture capitalist Josh Becker took over in 2011.[2] In 2015 the company was acquired by LexisNexis.[1] Former CTO Karl Harris became CEO of Lex Machina in 2018.[8]
