The owner of the “Peanuts” music catalog files a copyright infringement lawsuit alleging unauthorized use of its tunes. According to reporting, the case targets the U.S. Interior Department and three companies, with the plaintiff asserting that the defendants use the catalog without permission. The filing asks that the parties stop using the music and addresses claims that the alleged conduct violates the plaintiff’s copyright rights. The dispute centers on licensing and permission, with the plaintiff contending that its cataloged music is being used commercially or otherwise without obtaining the necessary rights. The New York Times and Winnipeg Free Press both describe the lawsuit in similar terms: the “Peanuts” music owner is bringing claims against multiple private firms and a federal agency, arguing that their use of the music is illegal. The coverage does not indicate that the defendants have been found liable, and it presents the matter as ongoing legal action. The complaint reflects an effort by the rights holder to enforce its claimed ownership of the music and to prevent continued use without authorization.
