Welcome to Skilled in the Art. I’m Law.com IP reporter Scott Graham. Here’s what’s crossing my desk this week:

  • It’s the Battle of Big Pharma as Amgen, Sanofi and Regeneron return to the Federal Circuit to fight over ground rules for antibody patents, with Bristol-Myers Squibb, Merck, Eli Lilly and Pfizer along as amici.
  • BlackBerry faces the first of two big hurdles to revive its messaging patent suit against Facebook and Snap.
  • Vizzi overcomes Brizzi in the early round of a trademark dispute over hard seltzer drinks.
  • CareDx organ transplant patents still eligible following extra judicial scrutiny.

As always you can email me your feedback and follow me on Twitter.
