Patent Infringement Claims Dismissed For Failure To State A Claim Because An Affirmative Defense Applied

Mar 23, 2015

The defendant moved to dismiss for failure to state a claim on the basis its activity was covered by the HatchWaxman Act’s safe harbor provision for clinical testing during the term of the patent. The plaintiff countered that the safe harbor was an affirmative defense and it was entitled to discovery to test the factual basis for the defense.

The court accepted that “generally an affirmative defense cannot serve as a basis for a [12(b)(6)] dismissal.” However, the court noted that if a complaint’s own allegations on the face of the complaint indicated the existence of an affirmative defense, dismissal could be proper under 12(b)(6). The court then likened the case before it to two other cases where the claims had been dismissed because the plaintiff had failed to allege any specific act of infringement not covered by safe harbor provisions. Finally, the court held dismissal of the infringement contentions was warranted because the plaintiff had only alleged the defendant used the patented technology in protected new drug investigational activity.
