Sonic Indus., LLC v. iRobot Corp. No. 13 C 9251, Slip Op. (N.D. Ill. Feb. 28, 2014) (Shadur, Sen. J.).

Judge Shadur sua sponte struck portions of defendant iRobot’s answer and affirmative defenses, and allowed other portions to be repled.  Of particular note:

• The Court struck iRobot’s noninfringement affirmative defense for committing the “cardinal sin” for an affirmative defense of not accepting plaintiff Sonic’s well-pled allegations.
• The invalidity defense was stricken with leave to replead it in a “more particularized and fleshed-out form.”
