They probably mean Motorola's extremely aggressive behaviour; the two high-profile Motorola suits aren't defensive, in that Motorola sued first. The Apple one was initiated long before the Google acquisition, and is thus nothing much to do with Google (though Google have said they'll continue to look for the frankly insane terms Motorola wants); however, the Microsoft one was initiated during the acquisition process; it'd be normal for Google to have some control over litigation at this point.
