Warner Bros

Warner Bros., one of the major players in the entertainment industry, has a rich history dating back to its founding in 1923 by brothers Harry, Albert, Sam, and Jack Warner. Initially established as a film studio in Hollywood, Warner Bros. quickly gained prominence with early successes like "The Jazz Singer," one of the first synchronized sound films. The studio became known for its innovation in film technology and its introduction of iconic characters like Bugs Bunny and Daffy Duck. Warner Bros registered their first iconic logo trademark with the United States Patent and Trademark Office (USPTO) on September 3, 1935.

Over the years, Warner Bros. expanded its reach into television, music, and various other forms of entertainment. The studio has produced a vast array of successful films and TV shows, including the Harry Potter series, DC superhero films, and Friends. As a major entertainment company, has been involved in various legal disputes over the years. One prominent case involved a prolonged battle over the copyright ownership of Superman. The heirs of Jerry Siegel, one of Superman's co-creators, sought to reclaim the rights to the iconic superhero. The legal saga resulted in multiple court decisions and settlements, ultimately allowing DC Comics, a subsidiary of Warner Bros., to retain the rights to Superman. However, the legal wrangling continued for an extended period. In another notable dispute, Warner Bros. took legal action in the case of the "Harry Potter Lexicon," a fan-created reference guide to J.K. Rowling's Harry Potter series. Warner Bros. argued that the book, which was not officially endorsed, infringed on its copyrights and posed a threat to the commercial success of the official Harry Potter franchise. A federal judge ruled in favor of Warner Bros. in 2008, blocking the publication of the unauthorized lexicon. However, the author was later permitted to publish a revised version with Rowling's endorsement.
