Microsoft has accused rival Google of pushing Android handset makers to use its applications such as YouTube and Maps.
Along with Oracle, Nokia and 14 other tech firms, Microsoft has filed a complaint with the European Commission.
The group, known as FairSearch, argues that Google is abusing its dominance of the mobile market.
In response to the filing, Google said: "We continue to work co-operatively with the European Commission."Microsoft and Others Back FairSearch Complaint In Europe Over Google Android Apps [bbc.co.uk]
"We are asking the commission to move quickly and decisively to protect competition and innovation in this critical market," said Thomas Vinje, Brussels-based counsel for FairSearch.
"Failure to act will only embolden Google to repeat its desktop abuses of dominance as consumers increasingly turn to a mobile platform dominated by Google's Android operating system," he added.
