Ronald Isley Is Being Sued By Rudolph Isley Over The Isley Brothers Trademark

Rudolph Isley is suing Ronald Isley, over The Isley Brothers trademark, requesting a 50 percent share in the group's earnings.

Nobody wins when the family feuds. In legal documents reviewed by TMZ, it has been reported that Rudolph, 83, is suing younger brother Ronald, 81, over The Isley Brothers trademark. Rudolph claims that his younger brother made business transactions without informing him, and has also successfully applied for TIB trademark last August, since collecting all of the group's profits.

Rudolph now wants a share of proceeds that Ronald has allegedly obtained since taking sole ownership of the group's trademark. Documents read that Ronald was granted exclusive rights to “visual recordings and audiovisual recordings featuring music and animation.”

Rudolph, an original member of TIB since their iteration in 1954, retired from music in 1989 to become a Christian minister, although last performed with his brothers during the 2004 BET Awards. The group – consisting of Ronald, Rudolph and O'Kelly – briefly disbanded in their brother, Vernon, was killed in a car accident at 13-years-old. The group later reformed as a trio, later adding younger brothers Ernie and Marvin, along with instrumentalist, songwriter and producer Chris Jasper. O'Kelly died in 1986, the same year that Rudolph claims that he and Ronald began to split all profits of TIB. O'Kelly's death came nearly 25 years before Marvin, who died in 2010.

The current TIB lineup consists of surviving members Ronald and Ernie, who released their latest album, Make Me Say It Again, Girl, in 2022. Guest appearances on the album include Beyoncé, Snoop Dogg, 2 Chainz, Trey Songz, Quavo and Takeoff, who died just one month after its release.
