Pulse Analysis

The rapid expansion of generative‑AI tools has put the use of large, scraped datasets under intense legal scrutiny. Adobe’s recent derivative complaint spotlights this trend: the company’s SlimLM series was allegedly trained on the Books3 corpus, a collection of hundreds of thousands of copyrighted books obtained without permission, and on the publicly available Common Crawl archive, which also contains unlicensed material. Plaintiffs contend that Adobe’s directors knowingly approved the “ask forgiveness, not approval” approach, exposing the firm to a wave of copyright lawsuits that have already driven the stock down more than a quarter and forced CEO Shantanu Narayen to resign.

From a corporate‑governance perspective, the lawsuit translates traditional intellectual‑property risk into a direct D&O exposure. Shareholder derivative actions can allege breaches of fiduciary duties, waste, and securities‑law violations when executives fail to oversee AI data‑sourcing practices. Insurers are now forced to consider whether existing D&O policies cover such AI‑related claims or whether new endorsements are required. Boards must therefore embed robust data‑audit procedures, obtain clear licenses for training material, and document risk‑mitigation steps to satisfy the business‑judgment rule and fend off future derivative suits.

The Adobe case is likely only the first of many where AI‑driven IP disputes cascade into director liability. Similar pathways exist for privacy breaches, bias allegations, and other tort claims that could be leveraged in D&O litigation. Companies should treat AI governance as a material risk factor, integrating it into enterprise risk management frameworks and reporting to shareholders. Proactive measures—such as third‑party data verification, transparent model documentation, and regular board briefings—can reduce the probability of follow‑on lawsuits and help insurers price coverage more accurately in an increasingly AI‑centric market.
