Copyrights of Superman and Lois enter public domain after 10 years

According to foreign media reports, the copyrights of the characters Superman and Lois will enter the public domain in 2034, followed by Batman in 2035, the Joker in 2036 and Wonder Woman in 2037.

By then, a large number of unauthorized Superman and Batman comics will enter the market, but Warner DC has registered the "Man of Steel" and "Caped Crusader" trademarks, as well as Superman's "S" and Batman's logo. Even if they enter the public domain, other creators can only use the early images of Superman and Batman, and cannot infringe on DC's trademark rights, which will still limit their creative ability.
