In general, whether or not to register a copyright is a private decision. Copyright law does not require the registration of copyright works, as they are automatically copyrighted upon their completion. It is not necessary to register a copyright in Hong Kong, but in China . However, we encourage owners of copyright works to file applications for certificates of registration to facilitate future processing of following issues such as infringement, copyright transfer, change, cancellation and licensing. Services of copyright registration in Mainland China or the United States are provided by IPAS.
