Considering that the mobile area is quite litigated because of patents, how is Canonical preparing to deal with that when introducing Ubuntu for phones? Notice that Google didn't give it much importance at first and it and its partners have had lots of issues with them.
Google is now catching up by purchasing patent portfolios to have some defence or fire back, but price for thinking on this later rather than sooner is high. I don't want this to happen to Ubuntu phone nor Canonical or its partners.
