Motorola Mobility started the week off on a high note, winning separate rulings at the U.S. International Trade Commission that both Apple’s iPhone and iPad and Microsoft’s Xbox infringe Motorola patents. The decisions are preliminary, but they augur well for the cases — and for Google’s decision to acquire IP-rich Motorola Mobility in defense of Android.

On Monday Motorola moved one step closer to blocking U.S. imports of Microsoft’s Xbox 360 video game console when ITC administrative law judge David Shaw ruled that Microsoft had infringed four of Motorola’s patents involving Wi-Fi technology, video decoding, and methods of communication between the XBox and its accessories. In a one-page order, Shaw found that a fifth patent, also involving Wi-Fi technology, was not infringed, and that a claim in one of the video decoding patents was invalid.
