J. Geils has gone to court against the J. Geils Band. The guitarist is suing the group in U.S. District Court in Boston for "trademark infringement and deceptive business practices" by using the group name for an upcoming tour without him in the band. The group decided to tour without Geils due to a dispute with Francesca Records, which releases Geils' solo albums, and its claim to use the J. Geils Band name. Geils' attorney told reporters that the guitarist owns the trademark to the band name and has "never transferred it to anybody. These guys performed in Mr. Geils' band, but that doesn't give them the right to grab the name." The band's attorney, meanwhile, claims that Geils secretly secured the trademark in 2008, without informing his bandmates. The suit is seeking an injunction preventing the other members -- Peter Wolf, Seth Justman, Magic Dick and Danny Klein -- from using the Geils Band name during a nine-date tour that begins August 25 in Syracuse.
