Meta is facing a lawsuit for allegedly using libraries of pirated books to train AI models, with a fair use defense being asserted.
Motions for summary judgment have been submitted by both Meta and the rightsholders, focusing on the copyright infringement claims and fair use arguments.
The lawsuit involves accusations of Meta downloading millions of books from pirate libraries and uploading data via BitTorrent.
Meta argues that its use of contested books for AI model training qualifies as fair use and did not cause harm or competition for original works.
Experts provided technical insights on BitTorrent operations, with differing opinions on the probability of copyrighted data sharing by Meta.
Meta's expert revealed that the company uploaded around 30% of what it downloaded, potentially impacting the case's copyright infringement arguments.
The imbalance in data upload and download suggests Meta shared substantial data but questions remain regarding sharing copyrighted works.
BitTorrent specifics, including data blocks, were analyzed to determine evidence of copyright infringement in the case.
The case's technical complexities suggest it may not be a straightforward copyright infringement matter and could involve a trial to resolve disputes.
Both Meta and the rightsholders aim to sway the court in their favor with the presented evidence, anticipating a decision on the motions for summary judgment.
