The Suno litigation is no longer focused only on training data. Both sides are pursuing evidence about investment due diligence, streaming activity and whether AI music substitutes for conventional recordings.
Universal and Sony are seeking materials from Suno investors, including assessments of legal exposure and projections about Suno’s effect on the music market. Suno, meanwhile, is seeking listening and royalty information from organizations including Apple and the Mechanical Licensing Collective.
Apple has moved to quash a Suno subpoena, while other non-parties have challenged document demands from the labels. These disputes matter because the fourth fair-use factor examines the effect of an allegedly infringing use on the market for protected works.
Do the subpoenas prove either side’s copyright position? No. They are evidence-gathering requests. Their significance depends on what is produced, what the court admits and how the evidence is interpreted.
