He has played the guitar since the age of nine and names The Cure, U2, and Stone Temple Pilots as primary musical influences, specifically the inventive use of technology and flood sounds used by those artistsU2's The Edge. His actor brother, Robert Patrick, was often seen wearing NIN shirts and pins while Richard was a member, as evidenced by his headshots from the time. This can also be seen on the behind-the-scenes footage for ''Terminator 2: Judgment Day''.
According to the biography on the official Filter website, Patrick was nicknamed "[[Piggy#Meaning|Piggy]]" during his time with Nine Inch Nails.
