The game included in its user agreement strong language against such activity, however. It forbade the creation of potentially infringing characters, and NCI had been known to rename or "genericize" such characters. The User Agreement additionally held players accountable to indemnify (reimburse) NCI and its affiliates against third-party infringement claims, and demanded either a granting of sole ownership in player created content, including characters, to NCI, or a warranty that a third party owner of the rights in player created content had made such a grant. It was unclear whether this grant was an exclusive assignment or a non-exclusive license, however.
