With statuary damages up to $150,000 per infringed work, the piracy lawsuit could impose billions of dollars in liability on Anthropic—the trial on this issue is scheduled for December
🌐 5. Precedent for AI Industry
Legal experts say this sets a critical precedent for other AI developers (OpenAI, Meta, Microsoft), affirming that using copyrighted materials for model training can be lawful under fair use entrepreneur
🥳 6. Industry Excitement & Cautious Optimism
Fair use advocates called it a major victory, highlighting the “purpose of copyright” being to foster creativity. But analysts warn that the piracy component still leaves legal exposure for anthropic
🔮 7. What’s Next
