I don’t think your update text is necessarily correct. You say Dunn was unable to prove plagiarism. This is incorrect. The legal document you link to says the case was dismissed because the New Jersey court did not have jurisdiction. It was dismissed for lack of jurisdiction, rather than on the merits of the case. Furthermore the case was dismissed without prejudice which means Dunn and his legal team is still able to file a claim of plagiarism in the correct jurisdiction. Given that neither party has provided an update it suggests there is still a legal case ongoing.
