Welcome to Skilled in the Art. I'm Law.com IP reporter Scott Graham. Here's what's cracking this week:

• The PTO is moving fast and trying not to break things as it implements formal director review of Patent Trial and Appeal Board decisions, as required by the Supreme Court's Arthrex decision.

• The Federal Circuit is back in the live oral argument business, for one day at least next week. Morgan Chu and Josh Rosenkranz will kick things off with an appeal from a $1.2 billion judgment.
