"John Geils, founder of the J. Geils Band, has filed a lawsuit against the other members of the group over use of the name in an upcoming tour that doesn't feature the guitarist." You can read the full Rolling Stone article HERE.
This reminded me of how Wally Amos lost the rights to use the name "Famous Amos" in the 1980s after financial troubles forced him to sell the pioneering cookie company he founded in 1975, the "Famous Amos Company," which held the trademark to his nickname "Famous Amos." (In 1994, Wally Amos instead launched "Uncle Noname Gourmet Muffins," to considerably less fanfare.)
Today the "Famous Amos" cookie brand is owned by Kelloggs. But the ownership chain of the brand is really pretty amazing, as it turns out. Kellogs acquired the brand when it bought Keebler in 2001. Keebler came to own the brand when it purchased the President Baking Company in 1998. In 1992, President Baking Company bought the brand from The Shansby Group. And there were apparently four other owners of the well-travelled "Famous Amos" brand between 1985 and 1989.
