I wonder how many patents Microsoft filed on this tree.

  A search in Google Patents for "BW-tree" or "BW tree" turns up nothing (but I don't know how fast their database is updated or how long patents can be hidden or delayed).

    That's very good.

    It's likely that if it is patented, it's filed under an anodyne name like "A system and method for indexing data".

  What makes you think Google, Oracle or any other corporation who funds its research division with couple of billions of dollars wouldn't file a patent?
