It just dawned on me. Unisys and AccuWeather are competing providers of weather data, such as value added weather radar feeds. So my suspicion is that this may be more than just trying to get huge royalties. It may also be to try and cripple a competitor. I didn't see any mention of this in the CNET article, but I think it's important enough to bring up. It may even be relevant and further show why so many patents are really bad tools to put in the hands of business. It could help explain why they wanted so much from AccuWeather.
