Microsoft has appealed against a lower court order that would force it to start incorporating Sun Microsystems' Java programming language into Windows.
According to Reuters, the Redmond giant filed an emergency motion with the US Court of Appeals seeking a stay of the order forcing it to start shipping Java with Windows within 120 days.
Microsoft's lawyers dubbed the 15 January ruling by Baltimore US District Judge J. Frederick Motz as "extreme and unprecedented", and claimed that it would "inflict serious harm on Microsoft and Windows".
Sun's lawsuit alleges that Microsoft tried to crush its Java software, which powers rival technologies to Microsoft's .Net web services framework.
In his 23 December ruling, Judge Motz concluded that Sun had a good chance of winning the case and granted a preliminary injunction forcing Microsoft to include Java in Windows.
Microsoft then argued that having to quickly ship Java with Windows is too complicated, and that any glitches could end up harming large corporate users of Windows.
But Sun has complained that Microsoft wanted to take up to a year to include Java, and Judge Motz set a deadline of 120 days.
