Google, the subsidiary of Alphabet Inc., has announced plans to appeal a portion of a recent court decision in the ongoing US Department of Justice (DOJ) monopoly case against the tech giant, Reuters reports.

The case centers around allegations that Google holds an unlawful monopoly in the online advertising market.

On Thursday, US District Judge Leonie Brinkema ruled that Google was “willfully acquiring and maintaining monopoly power” in markets related to publisher ad servers and ad exchanges. Publisher ad servers, which are used by websites to manage and sell digital advertising inventory, are a critical component in how news publishers and content providers generate revenue through ads. Ad exchanges, which facilitate the buying and selling of digital ads, are similarly integral to the online advertising ecosystem.

In her ruling, Judge Brinkema determined that Google’s dominance in these two specific areas of online advertising technology was unlawful, finding that the company had engaged in anticompetitive practices by excluding rivals. However, the judge also delivered a mixed decision. She ruled that the DOJ had not proven that Google’s advertiser tools or its acquisitions of companies like DoubleClick and AdMeld were anticompetitive.

The DOJ had argued that Google’s conduct in the online advertising space was so monopolistic that the company should be required to sell off its Google Ad Manager, a platform that includes both the publisher ad server and the ad exchange components. Google’s appeal will likely focus on contesting the part of the ruling related to its publisher tools, arguing that they did not violate antitrust laws.

This legal battle is part of a broader effort by regulators to scrutinize and challenge the market power of major tech companies. Google has faced increasing antitrust scrutiny in various regions, with the US case representing one of the most significant challenges to its business practices. As the appeal process unfolds, it could have wide-ranging implications for Google’s operations and the broader online advertising industry.
