This isn't the first time they've tried this: another bad application (http://computerworld.co.nz/news.nsf/news/F68C4D35A4AE5DD5CC257038000F4A24) was submitted to NZ's patent office although it had been disallowed in other jurisdictions (including US) due to prior art. NZOSS representatives challenged the application and were able to force MS to change the wording to the point where it was no longer seen as a threat to developers.
Whenever Microsoft claims support for "improved quality patents" realise that what they mean is "other people's patents". Feel free to highlight their hypocrisy."
