Patent rights to karaoke

edit

Del Rosario held the patent to the Sing-along System, a type of karaoke he developed in 1975, and was consequently recognized as the sole patent holder of the karaoke system worldwide.[1] He filed a patent infringement case against a Chinese company before the Philippine Supreme Court [citation needed]. In 1996, the court ruled that the Chinese company violated his patent rights. [citation needed] Despite this, a book entitled Karaoke Idols: Popular Music and the Performance of Identity[2] credits Daisuke Inoue, a Japanese man, as having invented karaoke earlier in 1971.
