The creator of Spider-Man has been sued for $750 million and is facing legal action from share holders of a company over film and book profits.
Marvel, the company behind The Incredible Hulk and The X-Men, is also accused of violating copyright, which the company says was transferred to it in 1998.
Marvel has said the legal papers, which were filed in New York, are filled with “ridiculous claims”.
In 2005, Lee won a case with Marvel over profits earned on his creations.
The company whose shareholders are taking legal action against Lee is Stan Lee Media Inc, which he founded in the 1990s, but went bankrupt in 2001.
