Both firms are involved in legal battles over patents for smartphone technology and Xbox gaming software in the US and Germany.
US based software maker Microsoft has requested a UK judge to cancel Motorola Mobility's European patent protection for the use of technology for synchronising message updates on several devices.
According to Microsoft's lawyers, the software firm sued Motorola Mobility which Google had acquired in May claiming that all its devices powered by Android operating system use its technology.
Microsoft had filed a suit against Motorola Mobility in December 2011 in a preemptive challenge to a 2002 patent saying that it should not have been issued, according to Bloomberg.
Microsoft deputy general counsel David Howard told Bloomberg: "We're grateful for the chance to demonstrate that Motorola's claims based on this patent are unfounded."
Both the firms are involved in legal battles over patents for smartphone technology and Xbox gaming software in the US and Germany.
The software firm is seeking royalties from Motorola Mobility, while Google reveals that it owed royalties for the use of the Wi-Fi and video-compression technology on the Xbox.
The current case is running parallel to Motorola's decision awaiting lawsuit against Microsoft over the same patent in Germany.
Recently, the US District Court Judge has denied Motorola Mobility's request for an injunction on Microsoft's products after the mobile maker claimed that the products breach its H.264 patents.
