(Updated at 2:34pm on 1/8/10) "Federal Circuit Judge Alvin Schall moved to senior status in early October 2009. Judge Schall gave notice of his intent to take senior status in August 2009, and insiders knew much earlier. This delay leads me to question: Where is the next nominee? Chief Judge Michell has announced his intention to retire in the coming months and at least one additional slot will probably open in 2010. At some-point soon this backlog may begin to resemble the PTO...
The patent law community is ripe with attorneys who are smart, clear thinking, and experienced. My point is that the administration should move forward soon with a nomination."
