Washingtonpost has an insightful article about the absurdity of the Blackberry patent lawsuit. In that case, Blackberry is selling a proprietary service on which people become higly dependent (it is often nicknamed crackberry) generating a huge revenue stream for them, both in their country, Canada, and in the U.S. But NTP is suing them for patent infringment and what will happen is the service shutdown, unless Blackberry modify the software to not infringe the patent.

Note that Canada is no impacted by this due to patent law.
