argument: Notizie/News - Intellectual Property Law

Microsoft is facing a new lawsuit filed by US authors who allege that the company used their copyrighted books to train its artificial intelligence models without permission. The lawsuit accuses Microsoft of infringing on intellectual property rights by including entire books in its training datasets, seeking damages and an injunction against further use of their works.

This legal action reflects broader tensions in the technology sector over the boundaries of fair use and the rights of authors in the era of generative AI. The plaintiffs argue that large-scale ingestion of copyrighted works for AI training is not covered by fair use and undermines the market for books and writers’ livelihoods.

The case adds to a growing number of copyright lawsuits against major tech companies and highlights the urgent need for clearer legal standards regarding the use of protected material in developing AI technologies. The outcome could have significant implications for the AI industry, authors, and the future of copyright law.
