Welcome to Skilled in the Art. I’m Law.com IP reporter Scott Graham. In this week’s lightning round:

  • Lenovo goes tit-for-tat on standard-essential patents with Nokia.
  • BlackBerry messaging patents are ineligible after all.
  • The IPO window is wide open, and intellectual property suits aren’t going to shut it.
  • Swedish patent owner can’t sue London-based derivative trading optimizer in the Eastern District of Texas.
  • Ballard Spahr and Davis Wright Tremaine add IP laterals.

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