In a stunning development that shakes the AI industry, Scale AI has launched a major lawsuit against former employee Eugene Ling and competitor Mercor, alleging one of the most significant corporate espionage cases in recent tech history involving over 100 stolen confidential documents.
Scale AI’s Corporate Espionage Allegations
Scale AI filed the lawsuit on September 3, 2025, in the US District Court for the Northern District of California. The company accuses Eugene Ling, former head of engagement management, of systematic corporate espionage. According to court documents, Ling allegedly downloaded confidential files containing proprietary customer strategies. Many documents were taken immediately after Ling met with Mercor’s CEO. This timing suggests deliberate data transfer to a competitor. The lawsuit claims Ling accessed sensitive business information worth millions in potential revenue.
The Corporate Espionage Timeline
The alleged corporate espionage unfolded through several key events. First, Ling reportedly met with Mercor’s leadership while employed at Scale. Subsequently, he downloaded over 100 confidential documents. Then, he attempted to recruit Scale’s major clients to Mercor. Finally, he approached multiple Scale employees about joining the competitor. Court documents reveal Ling told “Customer A” he was “really excited about this new company.” This communication occurred while Ling still worked at Scale. The messages explicitly promoted Mercor’s services to Scale’s clients.
Mercor’s Response to Corporate Espionage Claims
Mercor co-founder Surya Midha denies the corporate espionage allegations. He acknowledges Ling possessed some documents but claims they remained in personal storage. Specifically, Midha states files were stored in Ling’s Google Drive. Mercor insists it never accessed or used Scale’s data. The company offered to have Ling destroy the files before the lawsuit. However, Scale argues Mercor refused to provide a complete file inventory. Scale also claims Mercor continued allowing Ling to engage with Customer A.
Industry Impact of Corporate Espionage Cases
The corporate espionage lawsuit highlights growing concerns in the AI industry. Major players like OpenAI, Anthropic, and Google face intense competition. Consequently, intellectual property protection becomes increasingly critical. This case follows similar disputes, including xAI’s lawsuit against former employee Xuechen Li. The pattern suggests systemic issues with data security in AI development. Companies now face heightened risks from employee mobility and trade secret theft.
Legal Implications of Corporate Espionage
Scale seeks substantial remedies for the alleged corporate espionage. The company demands monetary damages for lost revenue and reputational harm. Additionally, it requests an injunction preventing Mercor from using stolen data. Scale also wants all confidential documents returned immediately. The lawsuit seeks to block Ling from working with Customer A entirely. This case could set important precedents for trade secret protection in AI. Future corporate strategies may emphasize stronger data security measures.
Broader Business Consequences
The corporate espionage allegations complicate Scale’s recent business developments. Meta acquired a 49% stake in Scale for $14.3 billion in June 2025. This partnership aimed to enhance Meta’s AI capabilities significantly. However, some major clients have reportedly distanced themselves since the investment. The ongoing legal battle may further affect client confidence. Data quality and reliability perceptions could impact future partnerships. The case underscores how corporate espionage risks can influence major business relationships.
