Activision Blizzard is one of a number of firms to oppose Motorola Mobility's request to ban the importation of Xbox 360s to the US and cease sales of the console.
Along with companies including Cisco and IBM, which develops and manufactures components for Xbox 360, Activision argues it would "suffer commercial harm" in the event of an import ban, Foss Patents reports.
Motorola, which was recently acquired by Google, claims Xbox 360 infringes on five of the telecommunications company's patents related to "secure wireless communication and transmission of video content between controller devices and game consoles".
Activision said in a submission to the US International Trade Commission that, as "one of the United States' largest video game publishers", it "has expended and continues to expend significant resources to develop video games and accessories specially adapted to operate on Microsoft's Xbox gaming console".
The ICT is set to review all court rulings and issue a final judgement on US Xbox 360 imports on August 23.
