"Remember, Judge Grewal's prior interpretation found no disclaimer by the patentee that would affect this issue, and the language found in the patent prosecution history, on which he now relies, has been around since the patent was issued. Judge Grewal now says that the patentee disclaimed any kind of control signal, whether on-chip or not. Why so now, but not back then?"
I continue to believe this is the crux of the matter as it currently stands, but then again, I'm not a patent lawyer. So, as always, we shall see.
