A Modest Query Regarding 'Viviz' and the Precise Nature of Their Intellectual Property Transfer

Given that Big Planet Made Entertainment and The Sixtieth's collaboration with VIVIZ has concluded, and the members have recently signed with Uncore, I find myself curious about the legal standing of the group's name. The reports indicate a condition regarding the use of "VIVIZ" is under dispute, which suggests the term may be trademarked or otherwise controlled by a previous entity. Does the general public have access to any official filing or registration data on this, or is the negotiation entirely behind closed doors? ㅎㅎ It would be rather neat to see the exact phrasing of the claim.
