Over the years TomTom has built up a strong IP portfolio of navigation patents both through acquisitions and its own research activity. Because TomTom came rather late to the navigation space, when it started facing lawsuits (against Garmin) the Dutch company was in need of early, broad patents for cross licensing situations. Some of these were bought from Horizon navigation in June 2007 for $29 million. Within the patent set named in this litigation two were bought from Visteon and the two others from Horizon Navigation.
As usual, it is likely that these two lawsuits between TomTom and Microsoft will never make it to court, but rather be settled between the two parties before lawyer’s fees skyrocket into an endless trial.
