I feel that The SCO Group's role in the evolution of the System V ABI seems to have been more of a curator/editor than an innovator, inheriting the System V ABI from previous entities. Given that the Tool Interface Standard (TIS) Committee has essentially released the ELF-related chapters into the public domain, and others have made changes, it's unclear what specific rights The SCO Group (and now Xinuos) could claim to reserve. (That said, their maintenance work needs to be remembered.)
