 In the late 1960s, Steinway brought countersuit against "Grotrian-Steinweg" to stop them from using the name "Steinweg" on their pianos.Steinway won the case on appeal in 1975, forcing their competitor to use only the name "Grotrian" in the United States.The case set a precedent and established the concept of Initial Interest Confusion, in which consumers might be initially attracted to a similarly named but lesser-known brand because of the stronger brand's good reputation.
