French search company 1plusV has stepped up its battle with Google over how its algorithms rank sites, filing suit against the search engine giant in the French Commercial Court. It is seeking $423 million in damages from business it claims it lost due to alleged antitrust practices by Google. At $423 million, it is the largest claim filed against Google in Europe to date. This is not, however, the only accusation of anticompetitive behavior lodged against the search engine in Europe. Google has been the target of a handful of accusations, including prior complaints lodged by 1plusV.
