After the novel was bought out, the signature would usually be the original author, but the specific ownership might vary according to the terms of the contract. In some cases, the buyer may have the right to use the copyright first, meaning that the novel cannot be adapted into other forms of work without authorization. But under normal circumstances, the original author still had the right to enjoy the copyright and use it for commercial purposes, including adapting it into movies, TV series, games, or other forms of work. If the novel was bought out and used for commercial purposes, the original author could still ask for compensation.
