No, it's just the law of the Federal Circuit and only when interpreting 9th circuit law. Their decision is not binding precedent on any of the usual circuits, and their usual domain is patent law, not copyright law.
No. The Federal Circuit has subject matter jurisdiction, not geographic jurisdiction. Their decisions are binding precedent throughout the United States.
I think that is correct. This case is a little misleading because there were both patent and copyright claims at the district court level. As a result of the patent claims, the Federal Circuit had jurisdiction over the entire case, even though the copyright claims were to be adjudicated under 9th Circuit precedent. If they had only brought copyright claims, this appeal would have been heard at the 9th Circuit Court of Appeals.
