No, it's not about IP ownership, it's about whether those contributing the IP have waived patent rights. All contributors to a UEFI spec must be members - it's not acceptable for a member to contribute material on behalf of a non-member.

Almost everything in drivers/platform/x86, the ACPI support code under drivers/gpu, the PCC code for HP servers, some of the USB-ACPI glue (defined by a Microsoft spec), some of the ACPI/TPM integration (defined by TCG), some hwmon code, probably a few other bits and pieces.
