Berlin Court Rules Google AI Overview as Search Format

The Berlin court has ruled that Google's AI Overviews—the automated summarization feature displayed at the top of search results—constitute merely a "new search format." The court also determined that Google cannot be said to exert "decisive influence" over the displayed content. This lawsuit was filed by a German perfume company against Google and adds a judicial standard to the ongoing discussion regarding legal responsibility in AI search.

The lawsuit stemmed from the content displayed by AI Overviews. According to the perfume company, when its brand name appeared in search results, it was displayed alongside cheaper counterfeit products, and links to websites selling these products were also presented. Concluding that its brand was being treated on equal footing with counterfeit products, resulting in damage to brand image and sales, the company filed a lawsuit holding Google responsible.

The court dismissed the lawsuit and took the position that Google is not directly responsible for the content generated by AI Overviews. According to this logic, since AI automatically collects and summarizes information for display, Google merely provides the "display platform" itself. This approach means that AI-powered search is fundamentally viewed as no different from traditional search engines that list links to existing webpages.

However, contrasting judicial decisions have emerged within Germany. The Munich court ruled in a separate case that Google bears direct responsibility when AI generates erroneous answers. Nevertheless, the Berlin and Munich rulings cannot be simply compared because they involve different factual circumstances. Still, the fact that different interpretations of AI's legal responsibility have been presented within the same country is likely to influence future discussions.

The question of where to assign legal responsibility for AI-generated content is already being raised in various parts of the world. As the use of AI functions that summarize and edit information for presentation expands, it is becoming an issue how much responsibility service providers, information sources, and users should each bear. The Berlin ruling has become at least an example of German judicial interpretation that views AI search as an extension of existing search formats, and it is expected to serve as a reference case for similar lawsuits and regulatory discussions in the future.
