If I understand the issues correctly, there are two patents discussed.
The initial patent was about DishPro, after GC filed the infringement suit against E* in the Texas court, E* requested a patent reexamination and the USPTO found "all of the claims...were invalid." As a result the previous litigation was stayed by the Texas court. The reason for invalidating the DishPro patent was most likely that such invention was not an invention, many similar inventions preceded it.
Now GC got a new patent approved, it has to do with DishPro Plus. Immediately GC filed the new suit in the Florida court. If both patents are about the same technology, they are very similar, so it is possible E* may get the USPTO to invalidate this new patent too.
But even if this new patent is more "bullet proof" and more difficult to invalidate, assume this time around the USPTO had done a much better job to limit the scope of the patent, by virtue of a more bullet proof patent, it will be more difficult to prove infringement of such patent, simply because as I just mentioned, for a patent to be more bullet proof, the claim scope must be more limiting.
This is the similar strategy E* used in the TiVo case, while they failed to invalidate TiVo's patent during the 06 trial, they did not give up, now the USPTO agreed to reexamine the two software claims of the TiVo's patent because of new evidence provided by E*, if this time the USPTO invalidates the TiVo's software claims, the Texas court could also stay all pending proceedings in the TiVo case just like the Texas court did in the previous GC case, because E* only infringed on the software claims.
