Meta has denied downloading or sharing adult films to train its AI models.
It confirmed that a key IP address identified in the lawsuit belonged to the home of a former Meta data engineer, but says any torrenting from that connection was personal activity, not something Meta directed.
The lawsuit has expanded from 2,396 to 2,973 films, putting potential statutory damages at up to $446 million.
Meta admits it used BitTorrent to download some public text datasets for training LLaMA, but says those datasets did not include adult content.
One of Meta's more interesting arguments is that small BitTorrent uploads ("seeding") are too insignificant ("de minimis") to count as copyright infringement. It's a new legal argument that hasn't really been tested in court.
Meta is also keeping fair use as a backup defence, even though it's denying it downloaded the films in the first place.
The company is challenging other parts of the case too, including the validity of some of Strike 3's copyright claims and whether the potential damages are constitutional.
The case is heading to mediation in August, with a jury trial currently scheduled for February 2028 unless it's settled first.
