the right to evaluate the sound storage medium. Moreover, all were transferred: from "[...] interests [of Arthur's children] in all German audio recordings, bound books, pocketbooks, theatrical performances and electronic film recordings of theatrical performances to all existing derived products in Sony BMG". EUROPA developed a new audio book named "" based on it. Indeed, EUROPA avoided the use of the name "Die Drei ???" and also the name created by Kosmos because of the protection of the brand. Instead of that only characters and names which were based on Arthur's ideas were used (characters’ original names). The Kosmos publishing house continued its series of books under well-known titles and with famous character's names. The society filed a lawsuit against the Kosmos publishing house because Sony BMG itself saw its exploitation rights violated. A provisional disposal was obtained against the sale of two novels “Spuk im Netz” and “Der Fluch des Drachen” (both German only).

They found that the University of Michigan rightfully inherited the works of Robert Arthur and his characters, meaning that his heirs could not have transferred the rights to Sony BMG. A due date was set for the complainant of Sony BMG to submit the new chain-of-title as well as the new contracts as they were available to her. Eventually, Kosmos and Sony BMG negotiated again to come to an extrajudicial agreement, causing the delivery of Episode 7 of "DiE DR3i" to be delayed. The final release date of Episodes 7 and 8 was 30 November 2007. Outcome In February 2008, Sony BMG and Kosmos came to an agreement. The rights to the books as well as the brand name, which were the foundation for the audio dramas remained with Kosmos as well as all other publishing products, including calendars, non-fiction literature, mobile and computer games, science kits and board games. The rights to use audio material with the inclusion of the entire catalog as well as stage shows, plays and the commercialization of merchandise remain with the record label Europa. Since 4 April 2008, new German editions under the name “Die Drei ???” have been published, based on the
