"Bilski: Here we narrowed the scope for granting software patents. The USPTO's board of review is already invalidating patents based on the Bilski ruling.

Tom Tom is a Dutch company, but it's with the courts of the USA that Microsoft filed suit. Improvements in the USA also change what it means when other countries are pressured to harmonise with the USA."
