The Isley Brothers lawsuit: Ronald Isley accused of cutting brother Rudolph out of group’s profits

The Isley Brothers lawsuit: Ronald Isley accused of removing his older brother, Rudolph Isley, from the legendary musical group’s profits

Rudolph Isley has filed a lawsuit against his younger brother Ronald Isley over the legendary band’s trademarks.

Rudolph, 83, said in legal documents reviewed by TMZ that Ronald, 81, conducted business transactions without his knowledge that potentially cost him money.

In the lawsuit, Rudolph told the court that Ronald successfully filed to trademark The Isley Brothers name last summer and has since collected all the winnings.

Rudolph said in legal documents that he and his younger brother had agreed to equally split the band’s profits since the 1986 death of his brother and bandmate O’Kelly from a heart attack.

Rudolph said in court documents that Ronald violated the agreement they agreed to when he obtained the use of the name for “visual recordings and audiovisual recordings with music and animation” last August after filing an application in November 2021.
