You don't actually understand how this works.
1. In the Federal court system, all patent appeals go to the Court of Appeals for the Federal Circuit. This is true regardless of what district you are in.
Blame congress for this one.
2. Allowing folks who are admitted to any state bar is good. The entire state bar system is a disaster. In any other country, you are either allowed to practice in that country, or not. Here, we've further divided it into 50 states, and require lawyers to take 50 8-10 hour tests and fulfill 50 different sets of conflicting obligations (for example, continuing legal education requirements, pro bono hour requirements, etc) in order to be able to practice law in every state. It's not even possible. Any argument one could make that having to do this means you are more aware of the laws of that state or better able to practice in that state are ridiculous on their face to anyone who has actually had to study for and take a bar exam. If you practiced law the same way the various bar exams wants you to, you'd be disbarred.
So in short: Just because you read an article on wikipedia doesn't mean you know what you are talking about.
