If you believe that Dish "stole" anything from TiVo, you are severely misguided about the US' patent system. TiVo patented a "process". Dish accomplished the same process using different methods. TiVo's patent is like this: They patent the summing of numbers that equals "4". In their patent example, they show "2 + 2 = 4". Dish comes along and writes code that has to sum numbers to equal "4" also, but they do it with "1 + 1 + 2 = 4". TiVo sues them because they added up to .... "4".
Unless Dish got a hold of TiVo's programming source code, they didn't steal anything. This kind of process -- and many, many companies have ridiculous patents -- simply shouldn't be patentable.
The thing is they did.
