Major Authors Sue Microsoft: AI Training Raises Copyright Concerns

Major authors have filed a significant lawsuit against Microsoft, raising serious copyright concerns over the alleged use of nearly 200,000 pirated books to train its Megatron artificial intelligence. This legal action further fuels the ongoing debate about intellectual property rights in the age of AI. The authors claim the AI was explicitly designed to mimic their writing styles and themes.
The complaint, lodged in New York federal court, demands a court order to halt Microsoft’s alleged copyright violations and seeks substantial statutory damages, potentially reaching $150,000 for each alleged instance of misuse. The authors emphasize the critical role that massive datasets play in enabling generative AI to produce realistic and diverse content. They assert that the pirated collection was central to the AI’s mimetic capabilities.
Microsoft has not yet provided an official response to the lawsuit, and the authors’ legal counsel has not offered a comment. This case joins a growing list of high-stakes legal battles involving AI and copyright, including recent rulings in California concerning Anthropic and Meta, illustrating the evolving legal challenges facing the AI industry.
The legal fight over AI and copyright is expanding across various media. The New York Times and Dow Jones have sued AI firms over their archival content, while major record labels and visual artists are also pursuing legal action. Tech companies generally argue for fair use, maintaining that their AI creates transformative new content and that overly strict copyright enforcement could impede the progress of the AI sector.
