Sitting by designation, Judge Bumb recently considered a motion to strike several affirmative defenses and counterclaims. In Bayer CropScience AG v. Dow Agrosciences LLC, C.A. No. 10-1045-RMB/JS (Dec. 30, 2011), plaintiff Bayer CropScience brought an infringement action against Dow Agrosciences, and Dow raised various affirmative defenses and counterclaims. In considering Bayer’s motion to strike some of Dow’s affirmative defenses and counterclaims, the court was faced with the issue of what pleading standard applied. With respect to the affirmative defenses, Judge Bumb stated: “While the Third Circuit has not yet opined as to whether Twombly/Iqbal is applicable to affirmative defenses, this Court agrees with those courts that have found Twombly/Iqbal inapplicable to affirmative defenses.” Id. at 3. Therefore, the court “review[ed] Defendant’s affirmative defenses only for sufficiency and for compliance with Rule 9(b).” Id. at 4. Under this standard, the motion to dismiss the defense of equitable estoppel was granted, but the motion to dismiss the defense of patent misuse was denied. Id. at 7-11.
