This collaboration has two possible consequences: either it will turn POI into the greatest patent laundry of all time, or it will help Microsoft to launch a patent ambush on the project. Feel free to decide which one is more likely.

Since POI is being licensed under the Apache License, version 2.0, contributors are required to grant a patent license, which Microsoft has so far refused to do for OOXML. I think there are two possible outcomes: either we get a patent license through POI, or Microsoft may even introduce more patented code into the project (aka "patent ambush").
