The New York Times has filed a copyright infringement lawsuit against Perplexity, an AI search start-up whose user base and influence have expanded rapidly over the past year.
This is the second major legal action the Times has taken against a generative AI company, underscoring growing conflict between news publishers and AI firms over licensing, compensation, and the control of journalistic content.
At its core, the lawsuit raises fundamental questions: Who gets paid when AI models summarize or repackage journalism? And who is responsible when those systems generate false information?
This article breaks down the case, the arguments from both sides, and why the outcome could shape global AI policy.
Why The New York Times Sued Perplexity
1. Copyright infringement allegations
The Times says Perplexity used its journalism without permission and reproduced:
- Verbatim excerpts
- Near-verbatim summaries
- Abridged versions of Times articles
The lawsuit argues that Perplexity offers commercial products that substitute for reading the Times’ reporting, undermining its subscription-based business model.
2. Concerns over RAG-based outputs
Perplexity relies on retrieval-augmented generation (RAG), which pulls information from websites and databases before generating answers.
According to the lawsuit, this process frequently results in visible reuse of Times reporting, sometimes extremely close to the original text. The Times says this is not transformative use and therefore not protected as fair use.
Perplexity’s Defense
Perplexity argues that legal battles between publishers and new technology companies have happened for a century and rarely succeed.
Their partnership strategy with publishers
Before the lawsuit, Perplexity introduced a Publishers Program that offers:
- A share of advertising revenue
- Comet Plus, where 80 percent of subscription fees go to participating outlets
- A multi-year licensing partnership with Getty Images
However, The New York Times declined to join and instead escalated to legal action.
Previous cease-and-desist
Perplexity acknowledges that the Times sent a cease-and-desist letter last year asking it to stop using its content for summaries and AI outputs.
NYT’s Additional Concerns: Accuracy and Brand Damage
1. Alleged misinformation
The lawsuit claims Perplexity’s system has produced false information and attributed it to the Times. The publisher argues this harms its reputation and undermines reader trust.
2. Loss of traffic and revenue
By answering user queries directly, Perplexity may prevent readers from visiting the Times’ website. The Times argues that this causes measurable financial damage by bypassing paywalls, licensing, and subscription revenue.
How This Case Fits Into Larger Battles Over AI and Journalism
NYT vs OpenAI and Microsoft
The Times is already suing OpenAI and Microsoft for training AI systems on millions of Times articles without permission or payment.
OpenAI maintains that using publicly available data for training qualifies as fair use. The Times argues the opposite: that training models on their journalism without compensation violates copyright law and steals economic value from original reporting.
A wider industry effort
Other publishers, including those involved in a separate lawsuit against Anthropic, are watching these cases closely. The outcomes could set legal standards for:
- What counts as fair use
- Whether AI companies must license training data
- How responsibility is assigned when AI-generated content contains errors
What This Means for the Future of AI
1. A precedent for AI training and licensing
If the Times wins, generative AI companies may have to:
- License news content
- Share revenue through partnership programs
- Implement stronger attribution and citation standards
This could reshape the economics of AI development globally.
2. Clarifying the boundaries of fair use
Courts may need to decide whether summarizing, paraphrasing, or restyling news content is transformative enough to qualify as fair use, especially when the output competes with the original source.
3. Establishing rules for misinformation liability
If AI platforms are found responsible for misattributed or fabricated content, this case could influence future regulations on AI transparency and reliability.
TL;DR
- The New York Times has sued Perplexity for copyright infringement and brand damage.
- The Times says Perplexity reproduces its journalism without permission and replaces its services.
- Perplexity argues such lawsuits historically fail and points to its publisher compensation programs.
- NYT is also suing OpenAI and Microsoft on similar grounds.
- The case could redefine fair use, licensing requirements, and liability in the AI era.
