Core Viewpoint - Google is facing lawsuits from dozens of comparison websites in Europe, with claims totaling at least €12 billion (approximately ¥96 billion), accusing the company of "stealing their customers" [1] Group 1: Legal Context - The lawsuits are a result of a 2017 European Commission ruling that fined Google €2.4 billion for abusing its dominant position in search engines and favoring its own shopping services [1] - Following a ruling by the European Court last year confirming Google's violation of antitrust laws, plaintiffs no longer need to prove this in court, leading to a surge in lawsuits [1][2] - Currently, there are 12 civil lawsuits against Google in seven European countries, with nine of these cases collectively exceeding €12 billion in claims [1] Group 2: Ongoing and Upcoming Lawsuits - Several cases are set to go to trial soon, including a £1 billion (approximately $1.6 billion) claim from UK websites Kelkoo and the now-defunct Foundem, and a lawsuit from Compare Group in Amsterdam [3] - New claims continue to emerge, such as a €900 million lawsuit filed by LitFin in Amsterdam and a €2.97 billion claim from Italy's Moltiply Group SA [3] Group 3: Claims and Responses - Some plaintiffs have increased their claims significantly, with Idealo's co-founder raising their demand from €500 million to €3.3 billion, emphasizing the need for effective penalties against abuse of dominance [4] - Google has denied the allegations, asserting that its advertising features for comparison websites are functioning well and that it does not discriminate against competitors [4] Group 4: Challenges in Litigation - Despite the support from the European Commission's ruling, plaintiffs face challenges in proving that Google's actions directly caused their profit declines, which complicates the lawsuits [5] - Enforcement of any potential judgments may also be problematic, as plaintiffs might need to seek intervention from U.S. courts if Google refuses to comply with any awarded damages [6]
